[00:01:24]Let me tell you again what to do.

[00:01:26]Neither did I want to say that Yesterday we saw what chemical equations and I had talked about reaction on this so I will tell you What is a chemical reaction called?

[00:01:41]Let me tell you that chemical reaction who say When a substance is used alone or in combination with another substance reacts or combines with a substance If it is there or coincides with it, then whatever happens from it What happens is that you get a chemical equation is prepared and we can say that chemical The reaction takes place. Let us bring you again Let us tell you that here we will talk further.

[00:02:07]Yes, see yesterday we told you about chemicals What was the reaction described?

[00:02:19]Let's all start fast.

[00:02:21]Go and tell you a little about yesterday.

[00:02:24]Let me tell you. Yesterday we told you about chemicals.

[00:02:27]Reaction.

[00:02:29]Chemical reaction.

[00:02:31]Let us understand the matter.

[00:02:34]What is a chemical reaction? when two substance or a substance any one alone Substance Ok? or two substances combined or two substances together Okay, what does it do here? You're reacting.

[00:03:00]creates a new substance by New substances What will happen to the substance that creates it here?

[00:03:09]But it could be one, it could be two, it could be one Understand when it will happen and when it will happen To you any two substances combined to form a new substance Make. Ok? Will make one. Like we give you You told me what H2 + O2 together make.

[00:03:25]Makes it? Creates H2O. what makes?

[00:03:27]So look here two substances participated.

[00:03:30]Two substances participated. But here at What is happening sir? There are two substances here combine to form a new substance Is. What's happening to a new substance here?

[00:03:40]But? Arrival is taking place. Ok? New substances What is happening to you here? are you ready Have been. Ok?

[00:03:48]Are you understanding the matter? Here comes a new substance Have been. Ok? So this is our Chemical reaction. Did you understand? so all Press man and share today. You are your group Share it among your friends So that more and more children can join. Who The students of class 10th are with us To get the best marks here I can try and prepare. Ok? And We are very important to you people.

[00:04:10]thinking for you in ways how The child should score maximum marks and for that We are working. Ok? Let's talk Let's proceed further. So this was our chemical Reaction. Ok? And when we chemically describe the reaction by chemical formula This is what happens to me when I use it What? It is a chemical equation. chemical Equation.

[00:04:30]What happens? Equation. So we will discuss this topic We talked about this also yesterday. Ok? which if If you haven't seen it then go and see tomorrow's one Our last lecture is Day First.

[00:05:47]ok on topic Look Babu, yesterday we had studied the first topic.

[00:05:52]What did we study about chemical reactions?

[00:05:55]chemical reaction okay let's be careful Look, we will do it in a good way.

[00:06:01]are going to tell Let us tell you yesterday about chemical Reaction. Ok? Let's take the page.

[00:06:08]Okay, right? So that there is no problem in explaining it to you.

[00:06:11]No, no.

[00:06:26]Let go Let's talk about chemical reactions.

[00:06:31]Let's talk.

[00:06:40]Yesterday my first topic was Chemistry.

[00:06:43]Reaction. Ok? We are about this We are going to see the chemical reaction.

[00:06:47]Those. Ok?

[00:06:50]Yes sir my name is Ashutosh ji, remain Ashutosh, okay, let's go.

[00:06:56]Stay tuned everyone is fine and let's talk What is yesterday's topic that you did not understand?

[00:07:01]Today once again for revision Let us show it to those who understood it a lot.

[00:07:05]Good for those who don't understand it You will understand, I had said that Babu in this Look at the two substances that combine to form a new substance what will happen here, what will happen in this Any single substance is also a single substance ok or two substances combined into two substances together Creates a new substance.

[00:07:39]Creates a new substance. all We will talk about the topic, Babu. Building of; construction of Does.

[00:07:50]Does. Okay, right? Let us understand the matter. Here It was said that if we had a single substance Did you tell me what we did to CaCO3 yesterday?

[00:07:58]Had reacted. It was heated. what did you do Was it Babu? Had heated it. It is understandable To the point? what we did? It was heated.

[00:08:04]Ok? What to do during heating It happens? This breaks Babu. i.e. in CaO Calcium Oxide Plus Here's what you need Will be done? Yes, here in the form of CaO and O2 I will break it to you here. Ok? No Ca CO2 will be released here. Ok? CO2 It will come out. Ok? Let me tell you first. Let go Let me tell you. What happened here was that when We heated it. What did you do? Heated.

[00:08:33]So look, right now this is the only substance. Here Now just understand what I am saying? This is Tell me what the substance is. No one here alone It is a substance, Babu. What's here? someone alone There is substance. Ok? What does it do? Here But what to do? Let's heat it.

[00:08:47]Let's get the reaction done here. what do you do Are you brother? Get a reaction done. So what is this It happens? Look at this one here Calcium oxide has broken into pieces. What is it Is it done for you? Calcium oxide was formed. And What happened second? carbon dioxide becomes Went. To understand this, understand everything. here What is? Haven't even balanced it yet. Now some Have not done it. Just to explain to you What is a substance doing brother? to heat But when it is reacted, it It breaks. In how many parts? Look here One and one. In how many parts? In two. So What will be its multiplication factor? what about the aspect Will be done? It will be different. Ok? So this We call this a chemical reaction.

[00:09:22]This was it, what do you call aunt? A Bookish Definition What does bookish mean?

[00:09:28]Knowledge. Now let's bring our language.

[00:09:30]In. Ok? In my own style. Okay, right?

[00:09:32]Let go. If everyone lives in the house, village, then you You would know one thing if you lived anywhere.

[00:09:37]would know. Have you heard the name of curd and milk?

[00:09:39]I have heard the name. What do we say until milk is in I will not add any sour substance to it.

[00:09:45]So that curd cannot be formed.

[00:09:47]Are you understanding the matter or not? So there is a Was there any milk? Milk and plus another hum What did you give in it? Any sour substance, even lemon What will happen if you put it in? that yogurt bun Will go. Okay, right? Look here sour What happens here after mixing the substances?

[00:10:02]Is? There is a reaction. After the reaction What happens? A new substance is found here produces what we call curd Are. What do you say brother? It is called curd.

[00:10:11]Okay, right?

[00:10:13]Do you understand now? Did you understand this or not?

[00:10:16]Tell. So then we have a method that I will try to tell you. tell me please Brother in fast. Good Morning. Good Morning Suraj Yadav.

[00:10:30]Come on, everyone stay strong. Ok?

[00:10:33]Tell me, did you understand this? until the milk We mix the sour substance until Curd will not be formed until you mix it. Now look What are these two doing together here?

[00:10:42]Brother? is reacting. Reaction here doing. Okay, right? reacting like If it is there then what happens here? a new Matter is created. whose quality Tell me what is happening from that side? There is a difference.

[00:10:52]Okay, right? So that's why we define it I told you yesterday.

[00:10:56]sour substance in milk If you make it, the milk will curdle. Babu, you are not If you have seen it then let me tell you when milk What do I say about adding the name of the curd?

[00:11:16]What is produced when one gives curd?

[00:11:18]Babu Dahi, do you know what curd is?

[00:12:13]So let's talk, shall we? We people Who are we talking about? Do you understand now? When I will not mix curd in milk till then.

[00:12:21]It is always sour, Babu. As long as sour If you don't mix the substance, it won't be formed.

[00:12:24]Ok? Grandma, please go and ask mom here.

[00:12:27]They'll tell you what she says when They used to put lemon in milk, they used to put pickle in it Babu was there. Okay, right? Even then it becomes curd.

[00:12:35]Was. You don't know this experiment.

[00:12:37]will be. This is not even scientific. These are our Whatever grandmother has done is already done. So you You can do these things. Ok? So this The thing is that to make curd, it takes till it is cooked.

[00:12:46]Not until you add sour ingredients will form. You understood that No? Tell me. If you understand, then again Tell me yes or no. We will give you another way I will try to tell you. Tell me fast.

[00:13:25]Will it happen sir? Now understand aunty. to say two substances This means that there is someone like me here.

[00:13:30]But look at hydrogen and what's here brother When oxygen makes it react, What becomes here is the formation of water.

[00:13:38]If it happens then look here brother, give it here There is substance here, how much substance is there brother?

[00:13:43]The substance is fine, I understood it, put it here.

[00:13:46]It is a substance, what did we do with it brother?

[00:13:49]If we get the reaction done here, then a substance will be formed here.

[00:13:51]Look, it came here in the form of a substance.

[00:13:53]Did it come or not, tell me what is another substance?

[00:13:55]Tell me it is completely different from the previous one. First What should I tell the person? It is completely different. So This is our chemical reaction. This is ours What? Chemical reaction. Ok? watch now I told you this yesterday also. The Chinese told you You should remember this. Mixing sugar and water What happens? Tell. making of sherbet It happens. This is also a reaction, Babu.

[00:14:21]Ok? What is this even like? of a sherbet Construction takes place. So, this also gives you a There is a reaction. Ok?

[00:14:26]Yes sir. Let us move ahead. So we grow We are ahead. Today's topic is this, we What do you do? Let's talk and then We will move forward. Come, today we bring you chemical reactions between people Type. What have you brought? chemical Types of reactions. What we told you yesterday I told you about chemical reactions and Chemical equations were explained. Today we are We will study the types of chemical reactions.

[00:14:48]Types of chemical reactions include combination, dissociation, displacement, double displacement, exothermic, endothermic, neutralization and What do you say? All these topics that What do you say? You are going to come Under whom? This is a chemical reaction There are many more under which we will tell you What are you going to do? Topic here for you I am going to tell you. You guys stay put, stay strong Stay tuned and share your friends here.

[00:15:07]Keep sharing whatever you have. He came here and worked Can take less profit than. Ok? Let's talk Are.

[00:15:40]Look here, he's telling you guys here.

[00:15:42]Combination reaction. What are you saying brother?

[00:15:44]Combination reaction. So the combination reaction Who is called that? Understand. your language first Let me tell you. Bookish language will come again In. Ok? Because writing in the exam You don't have to write your language. Okay, right? They Do not write in rustic language. Okay, right?

[00:15:58]Come on, we are Biharis and you know that What do we do? the way in which one He wants to understand what we do with him.

[00:16:04]Are? Trying to explain it in the same way Are. Now look here Babu is saying What? That's what the combination is saying here.

[00:16:11]Combination means Babu, two men To combine to form a new substance.

[00:16:17]What to do? two new substances combined to form two substances combine to form a new substance Is. Okay, right? Well, tell us one thing.

[00:16:25]What to do? It was just mentioned here that H2 and + O2 Tell me Babu, there are many cow substances in it.

[00:16:32]Tell me what was said here? How much Is it a substance? Tell me here Tell me how much substance is there?

[00:16:41]Poonam Padar ji, tell me how much material is there here Now a substance is involved in it.

[00:16:45]How many substances are visible in the reactants?

[00:16:47]To you? Tell me Tell me, tell me fast.

[00:16:54]How many substances do you see? So we Two substances are visible here. There is one What is hydrogen and one, Babu? Oxygen.

[00:17:01]two substances combined to form a new substance What is he building? and the same substance Will build. The meaning of the combination is When two or more things combine to form a new If we create matter, we will What will you say? It is called a combination reaction.

[00:17:17]Ok? Now understand that one of our villagers and us I have prepared it for you. See There is a boy.

[00:17:28]Ok? And what is one? She is a girl. When their Marriage happens, wedding happens, so what is it?

What do you call that?

[00:18:15]Combination. This was our desi style. Correct Is? Let's come, what do we say?

[00:18:21]A little bit on bookish language. Ok? Because We also have to write. Look here, Babu.

[00:18:26]What is happening? C+O2 What are you saying? C+O2 combines to form CO2 What do you make brother? CO2 is the substance of the present Tell me what is reacting. how much substance Are you reacting? Tell me everything in fast Man.

[00:18:41]Yes, there are two substances. Now you will see two things.

[00:18:44]Tell me whether it is happening or not? What is coming to be made?

[00:18:46]Tell. I am just talking about the definition of a substance.

[00:18:48]I am not doing it. Just to explain to you I am talking about. So now two substances Two substances combine to form a new substance creating matter. What? a new Brother, who is creating the substance, this is it.

[00:19:01]You need to combine this what you need to combine Okay, now it has come to my mind, Mahi, it's okay.

[00:19:11]Okay, okay, okay, okay, now tell me brother here.

[00:19:16]But how much substance will be formed by mixing two substances?

[00:19:18]building a substance If he is doing this then this is what we call What to do when two substances undergo a combination reaction?

[00:19:27]What can be done when combined to form a new substance?

[00:19:29]What is it brother? Build it. So this is what we It is called combination. Ok? Let's come now A little bit of definition first. Correct Is? Then we will move forward. Okay, right? Let go Look here brother, it is saying combination reaction.

[00:19:40]Is. What are you saying? Combination reaction. Say that such a chemical reaction chemical reaction in which two or more a new substance formed by combining more substances What should we do? Build it. So that's what we What do you say? So that's what we call it Who to you? Combination reaction. But those whose What will be the root of the product? properties from the previous one It will be completely different. Like look here right now He immediately said that together with C++O2 they What did you do? made a reaction and the reaction What did I make? CO2 created. What did you make?

[00:20:08]CO2. Now here we know this is carbon and There is oxygen here. Isn't it? So this carbon And what did the oxygen combine to make? One Carbon dioxide was formed. As, you You know this is a gas. what would this be tell me is it? There is gas. Ok? here Look, you will get it in solid form.

[00:20:24]In whose form will I meet you? Solid. and this In the form of gas. Okay, right? So now understand here But what happened? When we react to both If done, a new substance will be formed in the form of gas.

[00:20:32]Did you get the total or not? Tell me what new substance is made.

[00:20:35]So this is what we call chemical.

[00:20:37]Which one in the reaction? Combination reaction.

[00:20:40]Ok? When two substances combine to form a new substance When two substances combine to form a new substance There can be more than two substances. Not one It is possible two or more things Used to be. How much are we talking about here?

[00:20:53]Of two or more. Ok? Career Board Good morning sir. Good Morning. Good Morning. So let's understand this combination.

[00:21:02]What is called reaction brother? When two or combining two or more substances to form a new substance If we build it then what will we do with it?

[00:21:09]What do you say brother? It is called combination reaction.

[00:21:12]What do you say? called combination reaction Are. Ok? Let us talk now Ahead. When we move forward in this matter, Look here brother, what is given here?

[00:21:21]Eko diya hai 2mg kya diya hai? 2mg + O2 What does it make together? Makes 2mg.

[00:21:29]2mgo now understand here it is done now E one Brother, you are looking at the substance, this has become a substance.

[00:21:36]And this is happening here with the addition of a substance.

[00:21:39]They are coming together, what are they making together?

[00:21:42]Brother? One is creating a substance. So this is it Your combination reaction. Do you understand now?

[00:21:48]What is a combination reaction called? All Write the man who did not understand Now tell me, do you understand, yes or no?

[00:21:55]I will tell you again when it comes Yes, please tell me Whoever did not understand, write in fast Then we will move ahead, till then see here But we fl what is there here is s so look here What is being formed, only Fe is being formed, isn't it?

[00:22:20]This is also a reaction. Here Fe What is Alag and S Alag combined to make?

[00:22:25]forming FeS. Okay, right? So this is also a There is a reaction. Look here, CO2 is here.

[00:22:30]that carbon monoxide and plus Oxygen is being combined and formed here What? creating CO2. Carbon here dioxide is forming. Okay, right? So this Babu, also see what is happening here.

[00:22:40]Is? Reaction is taking place. two men together What's a new guy doing? here A new man is being created. Okay, right?

[00:22:49]Please write it correctly, I am not able to understand.

[00:22:55]Okay, let's understand now.

[00:23:11]Let us understand it better.

[00:23:16]Look, Babu is saying only this here.

[00:23:19]Understand whether two substances will participate or more than two more than two Okay, let's take the first two here.

[00:23:34]Let us show. One he said is H2. Let's go here I will not tell you anything again and again It doesn't feel good to show it. Okay, right?

[00:23:42]Look here what is Baba saying? C+O2 Is. Ok? Now tell me what is in it Is? Tell me this fast and write in the comments.

[00:23:52]All men. This carbon is a different substance and What is oxygen? It is a different substance. So How many substances were there? That's two, right? We said two Or more than two. This is reacting.

[00:24:04]What did you create by reacting? Understand this. These CO2 Made. What did you make? CO2. So how now Don't see if you reacted. You react by See what you have created, just now if you We'll start to see how C reacts with O.

[00:24:19]How did we react to this thing?

[00:24:21]We will keep you well informed about the next chapter.

[00:24:23]I will explain it in detail, see what happens here.

[00:24:26]What, the carbon and oxygen in it One echo is negative and the other is positive It happens, like see here sodium Na+ What happens and what is Cl minus tell me It can lose an electron and it's taking an electron from somebody Will have to complete the octave. then this Reacts to form NaCl. what makes Is it Babu? Forms NaCl. Ok? So here But NaCl was formed. Don't know how it was made yet See. If you start looking at this now, Then you will not understand. I understood the matter To? So right now you just have to understand this.

[00:24:58]But that a man has come here. E Tell me. So this is one man and who is the other man?

[00:25:04]tell me is it? This is it. So how many people work together?

[00:25:07]Tell me what are you doing? two men two men together What did you make? Become a man, sir. Became a man.

[00:25:14]Do you understand now? When two men come together If you do the work of a man or become a man, then that Tell me what do we call it? Combination It is called reaction. Do you understand now?

[00:25:24]Tell me yes or no?

[00:25:27]Good. OK sir. I understood, sir.

[00:25:32]Let's move ahead now. Now let's move ahead. See Babu, this was our combination reaction. it What was ours? Combination reaction. Ok No? Now I have given you all these reactions.

[00:25:42]Are. You guys should see this. It contains Is it a substance? How many substances are in it? In this How many substances are there? And how many of these Is it a substance? How much material comes together first?

[00:25:52]What happened? creating a new substance Is he doing it or not? Look here creating a new substance that Is not doing it. Here too, each substance Is he building it or not? here too What are you doing? Tell me about each substance Is he building it or not? So that's what you're saying How many people can two people make together?

[00:26:06]Two men work together to develop a new substance We call it combination. Now So you must have understood yes or no.

[00:26:13]Please write. Ok? Let go Ok, I understood it very well. Let's go very Excellent. We also hope that you must have understood and by then you people Ask questions until you understand.

[00:26:25]Did not come. Okay, right? We are working for you Yes brother. We have no other work. Correct No? We are working for you, so your If we assume development in a good way If it didn't happen then what could we do, we couldn't do anything Now come, we are going to read the opposite of this.

[00:26:38]Brother, what are you going to study about dissociation reaction?

[00:26:40]Now here's the decomposition reaction, see All the men are looking at what a good thing Tell me four, if we tell you one thing, we ask you I ask you one thing, the opposite of something is correct.

[00:26:56]It is the opposite of one, like if we say one Om Now what will be the opposite of this? from one More Om will be created. Nor did the opposite happen. You Understand, we said We are thinking of such an example for you that Which will heat your brain directly.

[00:27:13]Ok? so that there is no need to rebuild it Fell. Ok?

[00:27:19]Let's go here we were talking. Yes, when a Will break the thing. Ok? like a thing If you break it, look here and accept it.

[00:27:26]Will slice. If you slice it here What will happen? into two or more parts Tell me whether you will have a son or not. two or more I will son Two or from whom? will bet that in more than two No? Tell me whether it will remain in one or the other Will it be less than? Please tell me this. Brother, please Tell. When they cut it into pieces, these two What do you call it in the part? two or There will be more than two that there will be just one Will it be less than this? Tell us this.

[00:27:55]Suppose we have Rs 10. This Have to distribute. What to do brother? Have to distribute.

[00:28:01]So tell me it will be less than 10. Piece will be. Isn't it? Be it a piece of ₹5, ₹2, ₹3 will be. But more piece by piece Tell me whether it will happen or not? There are 10 here right now.

[00:28:13]Can it be divided into 10 parts or not?

[00:28:15]Tell? So this means that it has more We can divide it into pieces. like here But look, there is something, we will break it.

[00:28:21]What to do? We will break it. So 100% sir Either there will be two or there will be more than two.

[00:28:27]Ok? Do you see this pen? These Can you see the pen? If you break this Tell me what will be received? either two pieces It will be possible to cut it into smaller pieces or even bigger pieces.

[00:28:35]Are. Can you do it or not? Tell me? So this is it Its opposite. a substance that was in combination Which is two together to make one. now saying Sir, the opposite of this is one which breaks into two.

[00:28:47]It will be made. What will happen brother? by breaking down What will happen? Two will be made. Ok?

[00:28:55]Okay, that's great. Now here we are, you I am going to tell people. All the best ways Look at it Babu. what is it saying here Please understand the question. Look at the questions first.

[00:29:05]saying that such a chemical reaction in which a substance is breaking down and saying in which a substance breaking into two or more parts What are you doing? Get divided. It is saying here that by breaking or disintegrating, that is, by disintegrating If it means something then it will break. what would have happened What does this mean? Breakage. through two or more It breaks down into more molecules. So What do we call that, brother? So the same What do we call this? We say Dissociation reaction. What do you call this?

[00:29:33]Dissociation reaction. Did you understand?

[00:29:36]Who understood it? Please explain the matter.

[00:29:38]Tell us. Write yes or no fast.

[00:29:41]Tell me who understood it? And who doesn't?

[00:29:43]Came?

[00:29:45]Yes If you are a new student, you should attend at least one class.

[00:29:54]Stay tuned. 100% direct to you Every question that bothers me today To. Ok? And if you read it like this You will go directly to the exam hall and write.

[00:30:04]There is no need to cram too much. to memorize here There is no need. Understand brother, go with your mind.

[00:30:09]Make a definition. No one's definition I have to write. No definition of a teacher I have to write. Ok? Prepare your definition Do it and go there and write it. remains written that the actual candidates should write in their own languages.

[00:30:20]What to do? Answer in your own language Please make it. Ok? Let me tell you, I understand Or not?

[00:30:27]Come on, let's talk, Babu. Look now Look at what you guys are doing a little bit.

[00:30:32]No? You people are so connected. Now!

[00:30:35]Till now likes are not increasing. What is the matter?

[00:30:36]Baboo? Like all the men first. Ok?

[00:30:39]Let's talk. said that such reaction A chemical reaction in which A substance breaks down or decomposes into two splits into two or more molecules or breaks down into two or more substances If it goes then what do we call it?

[00:30:51]Tell? What do we call that? same is called a decomposition reaction. what do you say Are you brother? Dissociation. Let's talk. Here But look brother C03 Is. Ok? We heated it. warm Did. What did you do brother? Heated. Like Heat So look here at calcium oxide.

[00:31:11]Plus look here CO2 is produced Is. What is it made of? This becomes CO2 gas.

[00:31:17]What happens? fades away. Please understand To the point. What is this happening? fly as gas Used to be. Okay, now let's give you an example.

[00:31:26]Let me tell you. I was telling you yesterday and you too Let me tell you.

[00:31:31]Look here, this is what the heat makers said.

[00:31:34]I had told the same thing. When we heat someone So it gets fragmented or broken.

[00:31:40]What happens? It breaks. such as values Let's just heat the pen here.

[00:31:45]Suppose we will heat it in the middle point.

[00:31:47]Please understand it with an example. heat it If we do this, will it break or not?

[00:31:51]Tell. Will it break? That means it will be divided into two parts Or not? Tell. This is what it is called. When the heat If you do it, it will be divided into two or more parts.

[00:31:57]What will happen? It will be divided. So look here Is it a substance right now or a substance of? These I have to tell you. Just tell me this much for now. One There is substance here, tell me brother, here is one Is it a substance or not? When I When heated, see here a substance is formed.

[00:32:13]This calcium oxide became a substance.

[00:32:16]What else happened here, tell me the second one.

[00:32:19]What happened to me, what happened to you here If you understand carbon dioxide CO2, then this Tell me what is happening in the two parts.

[00:32:28]Tell me if it is or not Tell me whether it is divided into two parts When divided into two parts, you can understand here When a substance breaks down alone, What should I say when a substance breaks down or to be broken or fragmented or to be in pieces You can see what Ke Do is saying here.

[00:32:50]form two or more substances So what do we call that?

[00:32:59]It is called decomposition reaction and comes Suppose in your language what one would say Are? family is. Ok? In the family you You know that if you say two brothers, three brothers, There are four brothers, so all of them are living together right now.

[00:33:11]Ok? As the days passed by So you see that all the brothers have their own separate Food, living, everything separates that No? So this is the breakdown. What is this?

[00:33:22]Breaking up, separation. to break up and part What do we say? dissociation reaction They say. What do you call that? Dissociation It is called reaction. Now you understand Must have gone. Ok? What did you understand that Don't tell me? We will move forward again. So brother Tell me if you don't understand, then we I will tell you. If we understand then we will rise again. Said here that calcium What is carbonate? when heated So here calcium oxide and carbon What happens when it becomes dioxide? This to you fades away. So here when a substance breaks down If it was there then tell me what happened to the two substances?

[00:33:52]Construction took place. So this is what we call it Dissociation reaction. What do you say brother?

[00:33:55]This is called decomposition reaction. Let's understand Did I come?

[00:34:03]No problem Babu, it is less now, then later It will be too much and if you are there then we Tell me what is the tension, you have come Share a little in the group and spread it.

[00:34:14]Try to do as much as the student will.

[00:34:16]You will enjoy reading it and so will we.

[00:34:18]We will tell you questions at every level.

[00:34:21]I'll try it, okay, no problem.

[00:34:24]Let's go, we'll take you along Next was my separation, what separation do you understand?

[00:34:29]Did you understand or not, tell me, my brother.

[00:34:33]And till then you guys take screenshots also.

[00:34:36]Tell me if you understood it fast or not.

[00:34:38]Tell me fast At least this many people are watching then at least At least write this much, just write two letters or So you have to write either yes or no, understand.

[00:34:50]If I came then write yes sir and if I did not come then write no.

[00:34:52]So say no sir, what is there in it, tell me and write it.

[00:34:55]In fast Let go Ok sir, I understood what Sintu Maurya said.

[00:35:07]It's a matter, how are Maniram ji, tell me fast.

[00:35:12]I understand that all men keep writing No, ok sir, yes sir, Chintu Ok Yes sir, I understand, let's talk.

[00:35:23]Babu, now move ahead from combination to dissociation If we move ahead, then let us look at one or two points in this.

[00:35:28]I have written it for you. what to say here Listen to what is happening. What is he saying here?

[00:35:40]Let's see what comes up here.

[00:35:43]Understand. What is it saying that dissociation The reaction is also called decomposition reaction.

[00:35:48]Is. This comes in the questions, aunty. Sometimes What does he do? No direct questions He asks indirect questions after asking. Correct Isn't it? Because the examiner also knows that Brother, the same question is coming. Okay, right?

[00:35:58]What will happen to the child if you give him the same thing again and again?

[00:36:00]It will seem that the same thing is coming, so who will Need to read? Let's go direct Whatever question comes, read it. Okay, right?

[00:36:05]So look here, now what has been said here?

[00:36:07]that this is another name for decomposition reaction Gave it. Tell what? Decomposition. And we tell Wherever decomposition or decomposed is written If so, you have to understand that There is something about to break down there. what are you Are you doing it brother? It's about to break. So This was very important for you. That's why We tried to write this point for you.

[00:36:26]You guys can also write this point like this Will take. Okay, right? What is he saying here?

[00:36:30]Decomposition reaction is also called decomposition reaction It is said. So it's not like I would ever say that Write the decomposition reaction then brain now I am feeling that brother, you have taught me.

[00:36:39]It was not known which decomposition reaction They say? So decomposition means separation.

[00:36:43]It happens. Decomposition also means breaking down.

[00:36:45]And what does separation even mean, brother?

[00:36:47]Breakage. So did you understand? Let's move ahead.

[00:36:50]It says here that combination reaction is a reaction of decomposition.

[00:36:52]The reaction is exactly the opposite. Brother right now So tell me that only. The exact opposite happens here Is. Now what was there? H2O H2 + O2 It was being made together, right? Look here for H2O Bun Had been. What was being made here? H2O One The substance was being formed. But what happens here Had been? one substance breaks down into two substances Construction is going on. How many are there bro?

[00:37:11]Tell me, matter is being created? Here But two substances are being formed. Correct No? So here two were coming together to make one.

[00:37:17]That is why this combination is called what is it called Tell me the combination but just reverse it here A person is falling apart and falling apart It is being divided here, so this is what it is called What is this called separation, brother, separation?

[00:37:31]ok so what happens to conjunction disjunction Tell me brother, it is exactly the opposite.

[00:37:35]It is okay, how are you feeling Sintu ji Tell me Sintu Maurya ji, how are you liking the class?

[00:37:39]Tell me all the men, tell me how is it fasting?

[00:37:41]It seems Tell me quickly, Sintu, how many people have come?

[00:37:45]Maurya ji, you guys did not like it, did you suppress it?

[00:37:47]Like all the men Like all the men Pressing and how it feels session definitely.

[00:37:52]You'll tell me, okay, let's talk.

[00:37:54]In the future, we hope that you You must have understood conjunction and disjunction.

[00:37:59]ok no, what do you do with it until then Take a screenshot so you can see it again If you don't have any problem writing, take a screenshot.

[00:38:10]Now let's talk about it here, Babu.

[00:38:13]Whose we will talk about next now An exothermic reaction. What is this Baboo? Exothermic reaction. into what It happens? See. Okay, now you know about tomorrow.

[00:38:24]Let me tell you. The one who gave you an example yesterday Were. Today let us give an example of the same thing.

[00:38:29]Okay, tell me one thing, have you ever whitewashed your house?

[00:38:32]yes? Are you making lime from lime? If If there are colors then this thing will be very good here.

[00:38:38]You will understand the way. Okay, right? Good You will see when we buy Chuna from the market and put it in water Look, here also two substances were found, Babu, one There was lime and what was the other one, tell me one was water What did I do when I put it in water?

[00:38:54]what happens is it starts reacting Babu does what both of them do begins to react like If it starts reacting, you will see that The temperature of the bucket in which You will put it in the vessel, what is that vessel?

[00:39:08]Babu, the vessel will become hot.

[00:39:11]What happens? warm. So, that's it.

[00:39:13]Reaction. Tell me what is this? Reaction.

[00:39:16]Have you guys ever done this? Tell me.

[00:39:21]Look here Babu, you will also get PDF, all You will also get notes. Second thing you need to know about the panel Whatever PDF is there, you will get everything.

[00:39:27]Recorded video will also be available. You all You will get the thing here. Okay, right? Just your job Have to stay here. What is the plan To you? Have to remain. Did you understand or not? when you If you stay here, all your things will be here.

[00:39:38]But it is going to be found. Ok? Let's talk We are ahead. Panel can be PDF or recorded Be it classes or PDFs, you will get everything.

[00:39:45]It was told here. Look, I'll show you Here's what we promise you I'm trying to give you all those things do. Check out our features Is? These are the features that we will tell you all here.

[00:39:56]Which is after live classes you will get recorded Arrangements have also been made for the classes.

[00:40:01]All Notes Panel PDF followed by Test You will find everything about the series here.

[00:40:05]Is. So you guys will try it here.

[00:40:07]Stay tuned. You have everything you You will get it here. as you see That every class is becoming regular for you. So What do you have to do too? Regular here Have to stay. Everything is good for you Will be explained. Okay, right? Let's talk Baboo. Ok. Let Radhika Kumari give you Did you understand what I said? So we were carrying What? I understood combination and separation. Now we What should people read? exothermic and Endothermic reaction. Look at this Bua exam I come a lot. Okay, right? So this It is also very important for you to understand the questions.

[00:40:37]Is. This is what you need to know about exothermic and endothermic reactions.

[00:40:41]Both reactions are sometimes endothermic If he asks, it is sometimes exothermic. Correct Isn't it? Okay, tell me one thing right now.

[00:40:48]Babu was giving an example that First came endothermic. Let's be exothermic.

[00:40:54]what will happen first will be exothermic Yes, it is good for you to understand that when Sir, did we put lime in water?

[00:41:05]When they were put in water, what happened here?

[00:41:07]Sir, what do you say here, it is hot and What if a gas keeps escaping when heated?

[00:41:14]Babu goes and a gas keeps flying.

[00:41:16]Please listen to what I say. So, what will happen here?

[00:41:19]Now understand this thing. Leave this thing also. Who You have to understand the thing, understand this. when here heat is generated here when they react It happens. What happens after mixing with water?

[00:41:30]Does it happen Babu? Heat is generated. What It happens? Heat. That is, we can say that Heat starts to escape. Sir, what are you?

[00:41:37]Tell me where it goes? heat starts to escape Is. So this is called Babu exothermic Reaction. What do you call this?

[00:41:44]Exothermic reaction. exothermic What would you call a reaction? when the heat is released begins or begins to emit So tell me what do we call that?

[00:41:54]What do you say? exothermic reaction They say. Did you understand? exothermic When will it happen? when after reacting What starts coming out after the reaction Should I go, Babu? When the heat starts to escape Tell me what do we call that?

[00:42:09]It is called exothermic reaction. What They say tell me? exothermic reaction They say.

[00:42:18]Let go Did Babul ji come and did you not like it?

[00:42:22]First of all, whoever is here, like it.

[00:42:24]Everyone please press like and share Let me tell you first of all, did you understand this?

[00:42:29]First tell me whether you have come or not, then proceed further.

[00:42:32]If we move forward, it will take just a second brother, yes or Write no, write yes or no, yes or yes Otherwise, whatever happens, we will talk to you later.

[00:42:41]I will tell you fast, yes or no, I understand.

[00:42:44]Did you come or not, tell me brother, tell me fast Radhika Kumari is saying yes sir I understand I came and told anyone whether they understood it or not.

[00:42:53]So many people are watching you guys Did you understand or not, tell me fast.

[00:42:56]Brother, tell me, tell me Yes sir, I understand, that's great.

[00:43:05]Manik Ram very good stay with us Today we are going to give you complete enjoyment.

[00:43:10]with the question so now you understand whether this Which reaction was ours? This was mine.

[00:43:15]heat AP when heat starts to escape. here See what's up Heat? this is It is being made. what comes out with it tell me is it? The heat is coming out, Babu. what to become Is it ours? Heat is coming out. Okay, right?

[00:43:28]Look here at carbon plus oxygen when If you burn it, CO2 will definitely be produced. and in the What will happen? Heat will be emitted. what are you Will you go brother? Heat will be emitted. Correct No? So this is what we call it It is called exothermic reaction. What They say tell him? exothermic Reaction.

[00:43:45]Babul, no sir, tell me what you did not understand Well, if you don't understand then you can do one thing now.

[00:43:51]Go somewhere in the house, there will be a mistress, even if He may become a food eater or what do you care?

[00:43:57]They say what they say, don't drink at home.

[00:44:00]What do we say at home?

[00:44:01]Let's do the whitewashing, okay, what should I do?

[00:44:03]Keep lime in water, it will be fine Well, not the best example for you guys.

[00:44:08]It will happen because there are many things which you will get in the lab I will find out by experimenting but that thing It could happen in our house. like lime If you put it in water, what will happen there?

[00:44:17]will be? What is Chu Chuna? hot there The vessel in which you will keep the water will be full.

[00:44:21]What happened? It will become hot. Why did it heat up?

[00:44:23]What is happening there? of heat Emissions are taking place. heat release This means that the reaction is exothermic It is happening. which reaction is taking place Tell? An exothermic reaction is taking place.

[00:44:33]Do you understand now? Tell me.

[00:44:38]Didn't you understand sir? Tell me what you don't understand I came? Babul ji, tell me fast.

[00:44:43]Only if you tell us will we move forward. Let's go if Until you tell us, we'll move on.

[00:44:48]Are. Ok? Let's see that now Endothermic. Okay, tell me one thing now.

[00:44:55]Telling about people's own experiences Yes Babu. See what happens sometimes Isn't it true that some people are unable to breathe?

[00:45:03]Breathing stops. Okay, right? so what about him It is said that oxygen comes from here due to pressure.

[00:45:08]What do you give him after applying it, brother? from here We are giving him oxygen.

[00:45:12]Or don't you tell me the time you should have left?

[00:45:15]If time is not passing then what are we doing here?

[00:45:17]brother, I am giving it to him, I am giving it to him what happened is that when chemical heat is required for the reaction or He needs warmth, what does he need, Babu?

[00:45:27]If we need heat, that's what we call it.

[00:45:29]Which reaction is called endothermic?

[00:45:32]It is called an endothermic reaction here.

[00:45:35]But look brother, the heat was coming out just then.

[00:45:38]giving it heat separately in the reaction itself Brother, this is what we call it What is an endothermic reaction called?

[00:45:44]tell me what you say tell me what you say Exothermic reactions are called fast reactions.

[00:45:50]Write in, did you understand this?

[00:45:53]The practical thing in your life is that thing I try to tell you so that you I want to understand what I said here, that when You will see someone start to gasp.

[00:46:05]What if he can't breathe?

[00:46:07]Oxygen is supplied from here Is. That means it needs to maintain its body.

[00:46:11]Tell me whether it is given for this or not. same You can see the heat sometimes. Good One thing to look at is rice.

[00:46:21]We were saying that rice should be mixed with water.

[00:46:25]Will rice be cooked by adding it to water?

[00:46:28]Babu, what happened? Rice will be prepared. We the people this We speak in our rural language. Tell me Will it be made or not? Tell. tell me my brother If it is not going to be made then to make it happen What should I do brother when I need heat?

[00:46:47]Till what do you call it, you won't give it heat By then he will become what he will not become.

[00:46:54]I can't react, okay, so that's it.

[00:46:56]Babu, this is what you call a reaction.

[00:46:59]Endothermic reaction was done by rice What else did you give him after that? You gave him water.

[00:47:06]After that what did you give plus from here you can make her hot I am doing it Babu. What are you doing? warm Are doing. This is what heating is all about Baboo? You are giving him heat. what to give Are you? He needs heat.

[00:47:18]So the heat that is needed is What do we say? endothermic It is called reaction. What do you say?

[00:47:24]Brother, I am calling it an endothermic reaction.

[00:47:32]Ok. Come on, if anyone has a problem Tell me brother. If someone does not understand Let us know and we will try to tell you.

[00:47:40]Ok. The reaction shown here is H2.

[00:47:42]And I2 is used here to make the reaction happen.

[00:47:46]What is happening to the heat, brother? if needed Used to be. So this is being made only after that.

[00:47:51]Okay, right? Look at N2 and O2 here It needs heat to make the reaction happen I am in need brother. So what is happening here Are you going there? Only then does it become NO.

[00:48:00]Is. Like now I'll tell you this in your language.

[00:48:03]that adding water to rice does not make it rice Gets made. Heat is needed to make it Does matter. what do we call that Brother? That's what we call endothermic That means it needs heat. Correct Is. Shall we move on? ok sir i understand Came. Okay, thank you very much. Stay tuned and You guys keep sharing the link fast.

[00:48:26]So many people are watching, brother, they don't like it.

[00:48:28]Yes, it hurts a lot. If from a query If you tell people that it is wrong then how sad it will be You guys will tell me brother when we are with you If you are working so hard for a little What will happen if you tip it from above?

[00:48:38]Tell me, if you are my brother then think about this a little.

[00:48:41]Brother, when we are working for you, then you Do something for me too brother, I am hungry and thirsty.

[00:48:45]People work for you, right? Let's do it now.

[00:48:49]Electrolysis reaction, understand this brother, if If you understand this thing then it will come in the exam.

[00:48:56]This is a question that has come many times, Aunty, okay.

[00:48:58]Yes, this question has started from 2018.

[00:49:02]What does he do in almost every session? Or So he asks in the first sing or second asks in Sing. But Babu, every session I ask. So what do you do?

[00:49:10]Understand the questions well Is. Okay, right? If you don't understand, repeat it 10 times Write. Sir, I did not understand, please write it 20 times.

[00:49:16]You will not understand until you understand I will try to explain it to you till then. Okay, right?

[00:49:21]I have full power to make you understand. Correct Is? Let go.

[00:49:27]Good. Let us understand it very well Sir. Very nice, very nice. Thank you.

[00:49:32]keep at it. If you remain, you will definitely understand Babu will come. Look, let's give an example that Somehow it is connected to our lives.

[00:49:38]It happens. So that's something on your mind.

[00:49:40]It will definitely hit. And when it becomes a hit, Babu.

[00:49:43]So once you study here, then you will not need to study anywhere else.

[00:49:45]There will be no need. In this way you Trying to teach. Ok? When If you study here then you will have to memorize the questions.

[00:49:52]Not required. Now tell me one thing Do we teach by looking at any definition?

[00:49:57]It is just written. What are we telling you Are? Endothermic. when heat is needed to him and when the heat is released It is called exothermic. say no Tell? You should know that when two men are brothers If we come together and build a man, he Composition Two friends come together to form an organization Tell me whether it is there or not? So this is the combination.

[00:50:16]Now separation means when there is a fight in friendship If it happens, they break up and start living separately.

[00:50:21]Yes or no, tell me? This is what dissociation is. His Later we studied exothermic and endothermic reactions.

[00:50:26]Don't read this only, tell me if there is anything else as good as this.

[00:50:29]Sir, I try to tell you that I come every day.

[00:50:32]Do you come to class every day? Yes, classes are held every day.

[00:50:36]Yes brother, classes are held every day, right? It's just yours.

[00:50:39]You are not present every day now, right?

[00:50:41]Let's talk about electrolysis here.

[00:50:43]What is a reaction called? Look here.

[00:50:46]What happens when an electric current flows What is done with this, it is broken Look here brother saying that such a chemical reaction in which by passing an electric current through a compound It is fragmented. what is done tell me is it? is fragmented. Like Heat What did I just tell you about heating it?

[00:51:06]Was doing. So instead of heating here, here But what should we do now? chemical method Have to do it from. So to do it chemically What will you do now instead of heat? Heat K We will pass electric current in this place.

[00:51:18]What will you do brother? electric current flowing Will do it and get it working. What to do?

[00:51:22]Will take the job. So look here brother NaCl What is happening here in NaCl brother?

[00:51:28]What are we doing in NaCl? Electricity The current is flowing. What are you doing?

[00:51:32]Are we here? by passing electric current Have been. Are you understanding what I am saying?

[00:51:37]Let electric current flow. and like If electric current is passed then these two breaks down into ions. Na+ and here Look brother, it breaks into Cl-. like you You know it has a plus and it Tell me what happens nearby? Minus. So this plus And what happens when you add minus? by joining Forms NaCl. what makes? Only then you It was told that Na has a plus sign and Cl has Tell me what you have? There is a minus. This is useless to him So this one will say take it and this one will say take it as you wish So its octave will be completed. So what is this Made it? This will become a friendship. NaCl It became a friendship. So this is what we give you Will teach. In the classification of elements that we Before teaching you all these topics, you Will teach. Okay, right? So you should pay attention to this I will keep it. Okay, right? So what happens here Are you doing it brother? to pass electric current Whatever happens after that is a reaction. Heat What are you going to do in place of this now? Electricity Let the current flow. Ok? then go What do we call what we become?

[00:52:31]Are? Then we call it electricity.

[00:52:33]It is called decomposition reaction. what do you say Him Babu? electrolysis reaction is called Are. Look here he is saying that such chemical reaction in which a compound Heat released when electric current is passed What to give if given? Now heat when heat is given Don't have to give. What do we have to give now?

[00:52:49]To conduct electricity. electric current To flow into it. Okay, right? like see Take a conductor wire. This is the wire, brother. Correct Is? And what should one do here? the magnet which What do you say? its direction needle It happens. Ok? Put it here. These Keep you. And I told you this in physics.

[00:53:06]It must have occurred that when current flows through a conducting wire If it flows then it has magnetism The quality is obtained. So what is here will be? As current flows through it, If its needle was from here to there, then this What will happen later, it will be like this This means that this stream from here what does it mean it is flowing The current is flowing through here, right?

[00:53:28]So you understand that this is about magnetism.

[00:53:32]When will the quality come when current flows in it Then you understand the matter as long as the current flows If not, it will remain neutral like a needle.

[00:53:39]It will be good, I have seen a car or a bike See, if you have seen bikes, you must have seen them.

[00:53:45]It takes one meter. Ok? He What is a meter? Tell me the name of that meter.

[00:53:52]Please give it to me brother. Ok? He comes in the exam.

[00:53:55]Name the meter. The meter on the bike Tell me his name. The meter on the bike Brother, tell me his name. Ok? it He comes in the exam. Okay, right? After that Come. So the meter that is installed in it when See when the car is not running Here it remains neutral, it remains at zero.

[00:54:14]Okay, what about driving a car?

[00:54:16]The meter slowly starts increasing What happens brother, the meter increases.

[00:54:20]It is this meter that starts increasing If it starts, it means that as electric current flowed through the vehicle What happened? Let me tell you what happened.

[00:54:30]It has started to get disturbed, it is like this now It was there, then later it will happen, so this It is said that it is okay to be disturbed, let's talk.

[00:54:36]Let's proceed further. So now we have to understand that where the heat What was being talked about there, what should I understand?

[00:54:42]Is? Just understand that electricity If the current is passed through it then it is divided into two parts.

[00:54:46]Tell me what happened? broke down. So this is what it is called When electric current flows, We get a reaction to it What do you say? We call it electricity Decomposition reaction.

[00:54:58]What are you teaching sir? Perhaps we think that you just did. You can also tell me after seeing It can be said that electrolysis reaction By observing the reaction one can say that Reaction is taking place. So right now this means You are currently studying chemistry.

[00:55:11]Baboo. Okay, right? Let us talk to you Here electrolysis reaction is understood.

[00:55:18]Came? when electric current is passed through What will happen to what we get by going there?

[00:55:22]They say? electrolysis reaction Will say. Babu, what will you say to this? This It will be called electrolysis reaction. Correct Isn't it? We will call this electricity Decomposition reaction.

[00:55:42]Ok? Now look what Babu is saying here.

[00:55:45]that electrolysis reaction is used What do we do as people? Its We will also read about it. Okay, right?

[00:55:52]The use of electrolysis reaction is We will read this. our daily lives There are many things that need electricity It is broken by passing current.

[00:55:59]Okay, right? So what do we even do about it do? Will flow. Now this is one thing I had read about the properties of magnetism. Good electric well see electric well If current is passed through it also The property of magnetism is acquired. Ok?

[00:56:11]As the property of magnetism is acquired, What happens? The bell goes and rings ton ton remains. Okay, right? So that too is an experiment for you.

[00:56:18]I will come. Okay, right? electric current It breaks when flowed. Okay, right?

[00:56:22]Let us consider the metal in electrolysis reaction.

[00:56:25]and oxygen at the cathode Oxygen or chlorine, which is a gas Where does it become free? It is saying this on the anode that when electrolysis reaction takes place So, it is the cathode of the metal i.e. positive.

[00:56:38]Babu, which point? positive At the point. You know, there are two batteries.

[00:56:43]There is a pole, Babu. Who would be the two poles?

[00:56:46]Is? One is negative to you and the other Tell me what happens? Positive. where at One is negative and one is positive.

[00:56:52]What are the names of negative and positive?

[00:56:54]It happens? Tell me fast.

[00:56:57]Brother, tell me the names of negative and positive.

[00:57:04]Tell me, it has two poles. So there is one One is negative and the other is positive. Whom Which one will be called anode and which one will be called cathode?

[00:57:10]Speak fast. Write all the men. something you People don't work. Some work for you guys They also leave it. You guys are so lazy We do. Ok? Let's go to electrolysis What does the metal say at the cathode in the reaction?

[00:57:22]and then oxygen or chlorine which This is a non-metal, Babu, and where is this non-metal?

[00:57:27]It gets deposited at the anode okay it goes to the anode and is released okay No, let's move ahead, till then you People tell me what do we call positive?

[00:57:36]and what do you call negative Some people call it anode and some call it cathode.

[00:57:40]I will say you have to tell me, okay, let's go.

[00:57:43]Let's talk about this, our photochemical reaction, this is what you get from photochemical reaction which is seen in many places Is. Okay, right? The trees and plants that you plant are ours He who reacts prepares food.

[00:57:57]So tell me how does it work? Photosynthesis He does it through this, right? That's what we are now There are readers. what happens here when That a photochemical reaction occurs. So You know that when photochemical If the reaction takes place, glucose will be Construction takes place. Tell me whether it happens or not?

[00:58:12]So that is also a reaction, Babu. what is that too Is? If there is a reaction, what kind of reaction is it?

[00:58:17]So that's a photochemical reaction you get.

[00:58:20]Is. photochemically, i.e., when exposed to light the reaction that starts the reaction What do we call that?

[00:58:27]It is called photochemical reaction. Correct Is? Let's talk about it here. Say that a chemical reaction that thrives in the presence of sunlight If so, what do we call it?

[00:58:37]It is called photochemical reaction. Baboo What do you call that? Photochemical It is called a reaction. Okay, right? Understanding Am I getting to the point? what do they say For him? photochemical reaction is called Are. Okay, right? Let's talk. We a little Let's go ahead. Look here, sir, here But there is carbon dioxide. what here Can you see it? carbon dioxide and water until the sun shines He will not cook food until then. Ok? So that The feast must have looked good because of this or You might have heard it in your village or somewhere else.

[00:59:08]Find out from someone who has knowledge of farming.

[00:59:11]Consider that the session in which there is no sunlight So what happens to the plant there, slowly He says what does it say and starts to fade away.

[00:59:20]Is it there or what happens in the plant?

[00:59:22]Why does the rotting quality come and go?

[00:59:24]Because he cannot eat his food.

[00:59:27]Cannot cook food, due to which The plant slowly begins to break down One starts to demeritize. Okay, right? So you this You can also understand. The second thing is to understand What did he want brother? to eat I needed something or the other. So the sun to him There was no light at all. while he gets water And the minerals were being obtained from the ground.

[00:59:49]I was taking it to the root. But What is there here? He doesn't get any light Due to this he is not able to cook his food.

[00:59:57]What causes this to happen? own Cannot undergo chemical reaction.

[01:00:01]Cannot undergo photochemical reactions Is. What happens because of this? that plant It either dries up or gradually It withers away. Did you understand the matter? So let's talk Babu, let's say here that when carbon dioxide reacts with water And what did he want in the first place? Light I needed sunlight and chlorophyll.

[01:00:20]Was. Okay, right? Chlorophyll means the leaf which It happens, it happens to be green. This was due to Is. Okay, right? So when in its presence What do we do? React brother So what is this? Look at this glucose He gets it constructed. who builds Is? of glucose. And this creates oxygen Does. That is why we have these trees and plants.

[01:00:39]It gives oxygen, right? As long as they accept Oxygen is not produced. oxygen Doesn't leave. It releases it. These What does it do? Babu will release it. So We will hold our breath until he releases it.

[01:00:51]I am unable to take it or not. So that's why It is said that when a photochemical reaction If not, what will our daily lives be like?

[01:00:58]will be? It will become chaotic. Okay, right?

[01:01:01]This is called photochemical Reaction. Ok? Let's say that such chemical reaction that occurs due to sunlight in my presence not in my presence In whose presence? of sunlight Fine in appearance. of sunlight in the presence Is. The reaction which is caused by sunlight What happens in attendance? It ends Or if he is poor then we will take him for granted.

[01:01:24]It is called a photochemical reaction.

[01:01:26]Ok? Look at the sunlight here.

[01:01:28]What is happening in the presence? have a reaction Used to be. Okay, right? The sun is here too Reaction taking place in the presence of light Is. So if this does not happen then that light It will not be called a chemical reaction. So the rest How do you guys like today's session?

[01:01:40]How did you like today's session? First, write fast.

[01:01:43]Then we will move forward. Write in fast How is today's session looking? Very beautiful.

[01:01:48]Very good sir. very nice. tell me how It seems?

[01:01:53]Vivek Kumar Aarohi should write what should he write about it Tell me what does it mean, Jai Hind, let's go Very good, tell me how are you feeling in fasting.

[01:02:03]How is today's session looking like? How many men?

[01:02:05]You guys are watching You guys are watching I am not writing, write fast about today.

[01:02:09]How is the session looking?

[01:02:13]Well, you are in 12th, in 12th, so you Everyone must have understood it very well.

[01:02:17]If I read the topic and you, I would be able to see you.

[01:02:20]It must be fun too, okay, let's go.

[01:02:23]Come on, tell me how you liked today's session in fast.

[01:02:27]If you guys like it, let's do it today.

[01:02:29]We take it from here today, The End then See you in the next session.

[01:02:35]If they come, the reactions that have
