[00:01:15]Miss has come as Miss Livia is the name of the Miss.

[00:01:18]The subject being taken is Chemistry.

[00:01:20]Okay, so first in chemistry.

[00:01:24]Chapter Chemical Reaction And the equation is already started at school.

[00:01:29]It must have been done. So in that chapter Isn't it an important topic?

[00:01:33]Balancing. An unbalancing There won't even be a question paper.

[00:01:37]Isn't it? For some children A difficult topic This will be balancing. So today How to balance live?

[00:01:45]Or what is a chemical reaction?

[00:01:47]Everything related to it We will discuss things. Ready Isn't everyone the same as a book and a pen?

[00:01:52]You should get it and be ready. Because We are balancing today.

[00:01:55]Going. Okay, let's get started. Then Before going into the video Look here, some friends.

[00:02:01]You can see all the photos too.

[00:03:05]I just learned it really well.

[00:03:07]Let's go, okay, then we'll have nothing.

[00:03:10]Coming soon to our topic today.

[00:03:12]Are you ready to go?

[00:03:15]Let's start with S.

[00:03:17]So we said Chapter One.

[00:03:20]Chapter One Chemical in Chemistry Say Reactions and Equations.

[00:03:24]We are discussing the chapter.

[00:03:25]The most important of them all We are the balancing act today.

[00:03:29]Let's see what you're looking at.

[00:03:31]So there are a lot of changes around you.

[00:03:34]Can you see what?

[00:03:36]Now, let's melt some ice for a change.

[00:03:38]It's water, isn't it? That's a change.

[00:03:41]Similarly, burning paper is also a Change is so many changes.

[00:03:45]You can see around you.

[00:03:46]Okay, let's make some changes.

[00:03:48]Look, you have to say something here.

[00:03:51]What are the changes here in each photo?

[00:03:53]What can I give you? Hurry up.

[00:03:55]Please comment. So what's the first thing?

[00:03:57]What is the photo? The first photo is milk.

[00:04:01]Milk is turning into a cadet, isn't it?

[00:04:03]What if I leave it open for a while?

[00:04:04]It will happen and it will become a cadet.

[00:04:07]What is the second photo, Ice Melt?

[00:04:10]Ice melts and becomes water.

[00:04:13]It is a photo that turns into water.

[00:04:14]What is given there next?

[00:04:16]Rusting of iron Iron rusting Or in the iron atmosphere Oxygen and water vapor React and rust.

[00:04:26]Let's look at the fourth photo.

[00:04:28]Wine is something everyone likes, isn't it?

[00:04:30]What if we come to Christmas?

[00:04:32]We will make wine.

[00:04:34]Champaka wine will be made in the same way What grapes make wine?

[00:04:37]A winemaker or winemaker We can see the photo there.

[00:04:41]A story about how grapes become wine.

[00:04:43]Change is the next thing people give.

[00:04:44]Look at that woodcut.

[00:04:48]A photo that turns wood into pieces You can see the same thing in Last Nuke.

[00:04:51]Isn't food something everyone likes?

[00:04:53]Here is a photo of the making.

[00:04:55]Okay, so this is what you can see, right?

[00:04:58]All the changes are of different types.

[00:05:01]Isn't it changes, all these changes?

[00:05:04]I have two classifications.

[00:05:06]It can be done in two.

[00:05:08]You can classify.

[00:05:09]You've studied, just say yes.

[00:05:12]Chemical Change and Physical Change Who is Rekha Biju? ​​Yes, Very Good Chemical.

[00:05:18]There are changes, there are physical changes too.

[00:05:20]So let's just have one.

[00:05:21]Remember, what is a chemical change?

[00:05:24]What is the physical stage up first?

[00:05:25]What can you see?

[00:05:27]Given is the physical state.

[00:05:29]What is the physical change in their physical A change is coming in the state, isn't it?

[00:05:34]Or what can I say, reversible?

[00:05:37]For example, ice melt will be It's done, it's water, now what?

[00:05:42]I can do this with water.

[00:05:43]It can also be turned into ice.

[00:05:45]A reversible change, then.

[00:05:47]It's a physical change, Nuke.

[00:05:48]Let's consider what's new.

[00:05:51]Substance RFO is a new There's no substance, right?

[00:05:55]After the water melts Ice melts and becomes water.

[00:06:00]Basically, it's frozen and then turned into ice.

[00:06:02]What is water?

[00:06:04]Physically, their new substance is nothing.

[00:06:07]There is no such thing as substance.

[00:06:11]Chemical Properties Beginning The properties of the substance and then Property of the incoming substance The chemical will be the same.

[00:06:18]No property changes.

[00:06:20]This is the physical change, what now?

[00:06:22]Chemical Chemical changes are not reversible.

[00:06:27]Burn the paper like a burnt ember.

[00:06:29]Is it possible to reverse it or not?

[00:06:31]So that's an unrecognizable change.

[00:06:33]Chemical change is next.

[00:06:35]Nokkikevon Omon Oh, there's some new substance there, or something.

[00:06:41]There will be, so go back.

[00:06:43]To come to the old state Can't wait.

[00:06:48]diff from regionalism first occurred And then there's the property of the person.

[00:06:53]Between the person who caused the accident and the property It will be completely different, right?

[00:06:56]So what kind of chemical change is this?

[00:06:58]I understand what a physical change is.

[00:07:00]I understand what a chemical change is.

[00:07:02]So, the children said, "Here."

[00:07:04]The photos provided are physical.

[00:07:06]Is it a change or a chemical change?

[00:07:08]You're the first to comment quickly.

[00:07:10]That physical change that turns milk into curd Is it a change or a chemical change?

[00:07:16]It's a milkshake, isn't it? What is that?

[00:07:20]It's an unrecognizable change, so let's What can I say, it's a chemical change.

[00:07:26]Can you say that next is next?

[00:07:28]Look, the ice has melted and turned into water.

[00:07:32]I have this ice melting and turning into water.

[00:07:34]If you freeze water, don't you get ice?

[00:07:36]So what is that? It's a physical change.

[00:07:39]Okay, now let's see what happens next.

[00:07:43]Rusting of Iron Rusting of Iron What is a chemical change or a physical one?

[00:07:47]What is Rusting of Iron?

[00:07:50]S It's a chemical change, right?

[00:07:53]That is, the oxygen in the iron atmosphere Reacting like water vapor It's oxidized after doing so. Ferric oxide Be. Then a new substance It is a chemical change because it occurs.

[00:08:05]Is. Next or What does that grace become? As wine Changing. You are the name of this process.

[00:08:12]Remember. Fermentation.

[00:08:15]You have studied fermentation.

[00:08:19]What is fermentation?

[00:08:21]Glucose sugar molecules etc. Break down and then drink alcohol.

[00:08:25]What do we mean by that process that occurs?

[00:08:27]Call it fermentation.

[00:08:30]Okay, so it's fermentation.

[00:08:32]Fermentation is a chemical change.

[00:08:37]Okay, look at this. I'll cut some wood.

[00:08:40]Okay, it's a chemical.

[00:08:42]Is a wood a change or a physical change?

[00:08:45]Cut it into pieces and comment yes.

[00:08:48]What kind of change has been made?

[00:08:50]That's a physical change, that cut.

[00:08:52]Even after that, what is it, Wood?

[00:08:55]That's right, it's a physical change.

[00:08:57]The last one to arrive is the Six One S.

[00:09:00]It's a chemical change, food cooks.

[00:09:03]There is a chemical change when So we have physical change.

[00:09:07]Look at the chemical change, look at this chemical.

[00:09:09]If change has taken place, we What can I say, there's a chemical there.

[00:09:14]To say that a reaction has taken place That's probably where this chapter ends.

[00:09:16]Relevance: There is a chemical change there.

[00:09:19]If it has happened, let's say a There has been a chemical reaction.

[00:09:23]That's how physical change is chemical.

[00:09:25]What does change relate to?

[00:09:27]Related to chemical reactions What we do is physical.

[00:09:31]Some of the terms change and chemical change Please look at the questions and answer them.

[00:09:35]Everyone is a witch of the following.

[00:09:37]Chemical Change Very Simple Question Chemical change in the given Find out which one quickly.

[00:09:44]Is it melting of ice after commenting?

[00:09:47]Does boiling water cause rusting of iron?

[00:09:50]Is it possible to dissolve sugar in water?

[00:09:53]Let's take a look at Melting Off one by one.

[00:09:56]What is the meaning of "melting of ice"?

[00:10:00]Ice from solid form to liquid A physical change occurs when the foam changes.

[00:10:04]There is only physical existence, right?

[00:10:05]There was a change in the state.

[00:10:06]There is only S, so this is a physical What is the boiling of water?

[00:10:11]What happens is the liquid turns into what?

[00:10:13]It turns into a gas, isn't it physical?

[00:10:16]A change in state This is also a physical change because it occurs.

[00:10:19]Is the third one S some people comment Rustim of Iron has done it.

[00:10:24]We know what rusting of iron is.

[00:10:26]They said it was a chemical change.

[00:10:28]So you got the answer, which one?

[00:10:30]Answer Rusting of Iron Last Option Look at dissolving sugar in water.

[00:10:35]Take some sugar and water.

[00:10:37]Is this a physical change after mixing?

[00:10:39]Is it a chemical change, that is, the sugar Same properties as water Is that being retained?

[00:10:46]This is also a physical Is a simple question?

[00:10:49]Well, if that's the case, then next Look at the question.

[00:10:54]EV of the following chemical Reaction A question asked in the board exam The question is which chemical is given?

[00:11:05]If the reaction does not occur or What hasn't happened is what has.

[00:11:08]The question is, what does this actually mean to us?

[00:11:10]Just ask what the physical change is.

[00:11:12]But we deliberately try to mislead You might ask, "So what are we?"

[00:11:15]You have to do the quest correctly.

[00:11:17]Read and give the correct answer.

[00:11:19]Isn't that a chemical reaction?

[00:11:22]No chemical reaction occurs or What is the physical change?

[00:11:27]To find out is to Look at what you're saying, Milk.

[00:11:30]Left open room temperature during summer What happened when the milk was opened?

[00:11:35]It turns out to be a cadet, doesn't it?

[00:11:37]What is this, a chemical change?

[00:11:40]I realized that option A is not big.

[00:11:43]Get Fermented Grace Fermented It turned into wine. So what is that? That too It is a chemical change. We are all ready.

[00:11:51]Discusted. So it's not B either. Now Si an iron nail is left Exposed to humid atmosphere.

[00:11:58]What will happen? That iron rust I will drink. So that's also a chemical.

[00:12:04]It's a change, isn't it? So which one is ours?

[00:12:07]Correct option? Melting of glaciers The snow has melted and turned white.

[00:12:12]It is a physical state.

[00:12:14]There is only change, right? So what is it?

[00:12:16]Our answer comes from the last option.

[00:12:19]Is there an option for melting of glaciers?

[00:12:23]Is it a physical change or a chemical change?

[00:12:26]It means that the reaction did not take place.

[00:12:28]Asking for the last option Option de-melting off The correct answer is Glashes.

[00:12:34]Rekhabiju very good correct answer S Then look at the next one.

[00:12:39]Just look at the question, assertion and Isn't it a reasoning question?

[00:12:42]A place where children have a chance to make mistakes Portion is the assertion and reason.

[00:12:46]How to make an assertion and reasoning The lady who was answering the question said, After saying, "I'll give you an assertion," Given is given.

[00:12:52]Alcoholic Beverages Process What is the meaning of fermentation?

[00:12:57]We talked about fermentation.

[00:12:59]The process that creates it is called Fermentation of alcoholic beverages Fermentation to make Using Is it correct for you first?

[00:13:09]The given statement is correct.

[00:13:10]Check if it is. That's how it is.

[00:13:12]Assertion and Reasoning You are atten Okay, is that correct?

[00:13:16]To make alcoholic beverages Using fermentation correctly So the assertion is correct now, right?

[00:13:23]What is the next reason given?

[00:13:25]Ifamation Identity of Initial Substance Notch Identity of the Initial Substance It doesn't change, does it?

[00:13:34]If it doesn't change, what type of Is the change chemical or physical?

[00:13:39]If it's change, it's not.

[00:13:42]The physical change is the same as the first person.

[00:13:45]It will be property then.

[00:13:46]If his attitude doesn't change, then it's Physical change is very good.

[00:13:52]What comes in Assertion? Assertion True It's about a chemical change.

[00:13:57]What is said is true or false?

[00:14:01]What is the correct answer?

[00:14:04]False, then you are making an assertion like this.

[00:14:07]And Reasoning Question Answer The first thing to do is to Is the statement correct?

[00:14:11]Check in case it's both.

[00:14:13]If it is correct, what check?

[00:14:14]Is this the correct explanation?

[00:14:16]They should check that.

[00:14:17]Is the correct explanation between?

[00:14:20]Check if it is clear.

[00:14:22]So, assertion and reasoning questions etc. You have to be careful when you are attending.

[00:14:25]A type of mistake children make Assertion and Reasoning are out of question.

[00:14:29]Is it clear yet? So let's go.

[00:14:32]If we get closer, then we Said Chemical reaction A chemical change in place If it happened, let us tell you what happened.

[00:14:44]There is a chemical reaction.

[00:14:46]It will be said that it has happened.

[00:14:47]If so, what is the chemical?

[00:14:49]Look at the reaction. This is a chemical reaction.

[00:14:52]Chemical Reaction Idamaka Ab of Chemical We are all ready for the boss's two phone calls.

[00:14:59]Said that there is a new chemical change How does substance exist?

[00:15:04]If only there were a new substance.

[00:15:06]The bonds will be broken.

[00:15:07]Or new bonds in the same form That's what the chemical reaction is, that bond.

[00:15:12]Breaking or making New substance after doing it What are we to be?

[00:15:16]What is called a chemical reaction It's called "Okay, chemical" We learned what reaction is.

[00:15:22]Let's look at a chemical reaction.

[00:15:25]Look at you in the text.

[00:15:27]An important thing to mention The reaction is the burning of magnesium ribbon.

[00:15:32]We took a magnesium ribbon and Take a burning magnesium ribbon.

[00:15:36]Show it in flame and burn it then.

[00:15:38]What can you see?

[00:15:39]Look, can't you see a white flame?

[00:15:42]It's better to say Dazzling White Flame.

[00:15:44]An eye-catching white Now you can see the flame.

[00:15:48]Look, here are the Ashes for you.

[00:15:50]You can see it happening, right? This ribbon knife is it?

[00:15:54]Nick is in form as the Ashes What are those ashes, you can see?

[00:15:59]Okay, magnesium oxide.

[00:16:01]What happens when magnesium ribbon is burned?

[00:16:03]Observation You saw the first Observation Dazzling White Flame There was a second option.

[00:16:11]Observation What is magnesium oxide form?

[00:16:14]Then each experiment was done.

[00:16:16]What should you pay attention to while studying?

[00:16:18]Observations that occur there Be careful, okay, magnesium ribbon bunwith Dazzling White Fum Anchus Ewhite Powder There was a white powder, that white powder.

[00:16:31]Who is magnesium oxide then?

[00:16:34]Expect questions like this.

[00:16:35]Let's do it. When burning magnesium ribbon A white powder appeared. What is That white powder? What? Magnesium It is oxide. Likewise, Dazzling White What does it mean when you say flame?

[00:16:45]Want to think? Burning the Maglian ribbon You should consider that one experiment.

[00:16:50]Okay, so these observations are all notes.

[00:16:51]Please do something related to this.

[00:16:53]Let's look at the question.

[00:16:56]Witch of the following is correct.

[00:16:59]Observation of Direction Shape In the experiment we just saw, What is the correct observation that was made?

[00:17:06]We do questioning and observation.

[00:17:08]Learned it properly and then from this You have read and made a correct observation.

[00:17:12]Some say brown powder off Is magnesium oxide a brown powder?

[00:17:18]What happened was magnesium oxide.

[00:17:20]But is it a brown powder?

[00:17:23]Didn't you say that white powder is brown powder?

[00:17:26]No, option A won't work, now look at option B.

[00:17:30]Colorless gas, lime Water milk or something like that Did we discuss it or not?

[00:17:37]Magnesium is no longer a second option.

[00:17:43]White light is what we said.

[00:17:45]It's burning with white light, that's what's happening here.

[00:17:48]Correct observation and last.

[00:17:51]Read the release of reddish brown gas It is said that sulfur is a brown gas.

[00:17:57]Is it true that what you say is true?

[00:18:00]Which option is option C Magnesium ribbon burn?

[00:18:05]With dazzling white lights, very good.

[00:18:08]That's the correct answer, okay, dad?

[00:18:11]Isn't it clear, then, that this kind of quest You can use the experiment part.

[00:18:14]Ask from Up Experiment Observation while studying, note accurately Okay, so you have to learn by doing.

[00:18:22]We said that a chemical reaction is taking place.

[00:18:24]We said the thing, then there was a reaction.

[00:18:26]How to tell if it's a chemical reaction?

[00:18:28]Maybe there are some observations in it.

[00:18:31]If you have any observations, please let us know.

[00:18:33]There was a chemical reaction taking place.

[00:18:35]What are observations?

[00:18:37]What is the first change in state?

[00:18:40]Change in state means two Gaseous substance is a waste.

[00:18:44]A solid substance became a gas.

[00:18:47]It's become solid, isn't it? What is that?

[00:18:50]Change in state two gases The reactants react It has become a solid There was a product in their state.

[00:18:58]Change has come, it's a chemical reaction.

[00:19:01]Observation is the second one, what is the change?

[00:19:04]In color, sometimes the color changes.

[00:19:07]The color of the solution will change, and that too in a It is the observation of a chemical reaction.

[00:19:12]Evolution of gas Gas can be transformed into form, change in What do you mean by temperature?

[00:19:19]I made a reaction and then that reaction The mixture can be cooled to a certain temperature.

[00:19:24]It may decrease or what will happen?

[00:19:26]It may be hot, the temperature may rise, that's it.

[00:19:28]What change in temperature next?

[00:19:31]What is the formation of the last one?

[00:19:32]What is precipitate?

[00:19:35]What do we mean by insoluble substance?

[00:19:38]Call it precipitate.

[00:19:39]For example, we have two colors.

[00:19:41]The solution was mixed and mixed.

[00:19:43]What form did the past form an insoluble?

[00:19:45]You can see the substance in it.

[00:19:47]What is that insoluble substance?

[00:19:49]Call it precipitate.

[00:19:50]Call me, this is what it is.

[00:19:53]What do you see in a chemical reaction?

[00:19:55]You are all correct in your observations.

[00:19:58]You have to study, it's not enough to study this alone.

[00:20:00]You can also see examples of this.

[00:20:02]You must have studied the examples.

[00:20:04]Let's look at the nugget.

[00:20:06]Just look at the reaction here.

[00:20:08]Between dilute sulfuric acid and Zinc granules i.e. sulfuric acid Here is the reaction between zinc and Given a test tube You can see what's in it.

[00:20:18]Sulfuric acid is for pickling.

[00:20:20]I'm going to take it inside.

[00:20:21]What did you do, put zinc granules in?

[00:20:24]So what can you see? Watch out.

[00:20:26]Look, what can you see?

[00:20:28]Can't you see the bubbles forming?

[00:20:30]What does it mean if there are bubbles?

[00:20:32]Let's understand from that, Bubble.

[00:20:35]There was a bubble in a reaction.

[00:20:37]If so, what does it mean to be a gas?

[00:20:39]There is a form there, OKable.

[00:20:42]If there is a gas there is a form.

[00:20:44]This test tube has been done as well.

[00:20:47]You touched it after the reaction happened.

[00:20:49]What will happen after that test?

[00:20:51]The tube will get hot, which is normal.

[00:20:53]It was at that temperature that the reaction occurred.

[00:20:56]You feel hot when you walk.

[00:20:58]We can see that there are two observations.

[00:20:59]Did you see the evolution of gas and Change in temperature then this is This chemical is a chemical reaction.

[00:21:07]Didn't we also mention the observation of the reaction?

[00:21:10]Hydrogen gas release occurred.

[00:21:13]Didn't you say that the gas is hydrogen?

[00:21:16]Hydrogen gas is a gas, how is it?

[00:21:18]How to make sulfuric acid Write EDF EDF Is sulfuric acid then zinc?

[00:21:27]What form will zinc form when it reacts?

[00:21:31]Sulfate Plus Seven What gas was there, hydrogen?

[00:21:38]The equation is clear now that there is gas, isn't it?

[00:21:40]What did you say when hydrogen became a gas?

[00:21:43]What happened to Faske Becomes Hot?

[00:21:47]Reaction is hot, change in Egypt The temperature also went up, and then there was a reaction.

[00:21:51]The changes that occur while studying Or the substance that occurs there Note exactly which ones.

[00:21:56]You have to study hard to clear it, okay?

[00:22:00]Then we can calculate the value of each observation.

[00:22:02]Let's learn by doing examples correctly.

[00:22:04]Just look at the first observation and see the S change.

[00:22:08]In state change, in state we are I said, "I studied an example."

[00:22:12]Should we put each thing in its place?

[00:22:13]You should also study the example.

[00:22:15]Look at the ammonia reacting with it.

[00:22:18]Hydrochloric acid to form ammonium Chloride is the reaction, so you You may have noticed ammonium here.

[00:22:25]Hydrochloric acid is a gas and gas is The ammonium formed after the reaction is Chloride is a solid and a gas.

[00:22:33]What combined to form a solid?

[00:22:35]Did you get a change in state?

[00:22:38]Then there's the change in state.

[00:22:39]This reaction after asking for an example Write down what their seeds are.

[00:22:43]The physical state should also be written down.

[00:22:46]Okay, I'll get the mark, next time.

[00:22:48]Just look at the change in color.

[00:22:51]Isn't that a change, look at that reaction, Iron?

[00:22:54]React with copper sulfate solution Two-form iron sulfite plus copper lla Sulphate and copper are forming, okay?

[00:23:03]So look, this is copper sulfate.

[00:23:06]Your experiment is a Copper sulfate solution in a beaker Copper sulfate solution is for pickling.

[00:23:12]Take a glass of copper sulfate solution.

[00:23:14]What color is this? What color is this?

[00:23:16]It's blue, isn't it?

[00:23:19]What did copper sulfate do then?

[00:23:22]You put a piece of iron on it.

[00:23:24]Or iron nail dipped You can leave it for a while.

[00:23:28]You can see this blue color.

[00:23:30]The solution is like this: fade fade fade To see the light turn green You may see a color change.

[00:23:37]What does that mean, Ferres?

[00:23:41]The color of ferrous sulfate is due to the presence of sulfate.

[00:23:43]What is the light? Green is a very good light.

[00:23:46]Green is why there is a color change.

[00:23:49]Okay, so this happened.

[00:23:52]Reaction is a color change for us or As an example of change in color You can give it to me and this iron piece You have a brown one outside.

[00:24:01]You can see the deposits.

[00:24:03]What is copper deposit?

[00:24:06]Okay, so this is an observation.

[00:24:09]Let's see in this one reaction.

[00:24:11]Can you change the color or change in?

[00:24:13]If you ask for an example of color, this You can write a reaction next.

[00:24:17]Look at the evolution of gas now.

[00:24:19]The example given is zinc sulfuric acid.

[00:24:22]Reacts to form zinc sulfate And hydrogen gas was created, what a Someone is giving an upward arrow.

[00:24:28]Can't you see there's no gas?

[00:24:30]It means that when it becomes gas, it I'll escape and go to show it.

[00:24:34]There is an upward arrow.

[00:24:35]Given OK Next Ch A change in temperature That is, for all of us, for all of us.

[00:24:43]This is a known reaction.

[00:24:45]Whitewashing and such You must have heard of lime powder.

[00:24:48]After you've made a mess and bit the walls, You may have heard of whitewashing.

[00:24:52]So here is a reaction to that.

[00:24:54]Calcium oxide is given.

[00:24:56]Take it and mix it in water.

[00:24:58]What can we get calcium from?

[00:25:00]It's not enough to get hydroxide, what else?

[00:25:03]There is heat, there is heat too.

[00:25:06]That means that the reaction mixture will be hot.

[00:25:08]It will be hot.

[00:25:10]Okay, so that's a change in.

[00:25:13]Temperature is an example of temperature.

[00:25:15]Okay, so that's a change in.

[00:25:18]For example, temperature Let's give it a last look at the formation.

[00:25:22]Off Precipitate Precipitate Just look at the reaction that occurs.

[00:25:26]Barium chloride plus sulfuric acid Gives Barium Sulfite Plus Hydrochloric acid i.e. barium Chloride and sulfuric acid react What happened to barium sulfate?

[00:25:40]Hydrochloric acid is also available now.

[00:25:42]You can see one here.

[00:25:43]Can someone see what's going on?

[00:25:46]That Downward Arrow That Nothing Downward Arrow It is His will to give.

[00:25:50]Precipitate due to precipitation That is to say, an insoluble The substance is the deposit below.

[00:25:56]When you're done, sit down and relax.

[00:25:58]They will show it to someone down there.

[00:26:00]It has been given, so in this reaction If you ask what the precipitate is, Write it down in simple terms, which is barium?

[00:26:06]Did you get sulfate?

[00:26:09]Every change or every observation You should study the seed example.

[00:26:14]Why are you telling me to study like that?

[00:26:16]Look at the short answer type.

[00:26:18]Question 2024 Short Answer Type Of A questioner who has asked a question Is Nokkerite One Chemical Equation Efa Chemical Reaction Evihatkan Place three observations.

[00:26:32]Maybe you can ask me to write an example. Let's see.

[00:26:35]What is the color example? Learn color change.

[00:26:38]Or a change in color that shows We learned the reaction example.

[00:26:42]I remember what that reaction was.

[00:26:45]Iron In copper sulfate What happens when you dip it?

[00:26:51]Happens Iron sulfate Copper is also produced.

[00:26:58]Oh, so you mean the color is blue?

[00:27:02]What is copper sulfate?

[00:27:05]Ferrous metal that is light green in color I want to mention the color as sulfate.

[00:27:11]There was a color change there.

[00:27:13]I only have a second to say it.

[00:27:18]Let me write another one, Miss Iron.

[00:27:21]How did Copper react?

[00:27:23]What color is sulfate? What happened to the blue color?

[00:27:28]What color is light green when sulfate is present?

[00:27:34]Plus Copper Okay, I should write an example like this.

[00:27:38]S, now change in, just look at the next one.

[00:27:41]You may ask for a temperature example.

[00:27:43]What is an example of change in temperature?

[00:27:45]The reaction to our whitewashing Calcium oxide mixed with water What form does calcium take when it is made?

[00:27:53]Is hydroxide forming or not?

[00:27:56]There is something else going on.

[00:27:59]There is also heat, which means The temperature is rising. Very good. Okay.

[00:28:05]Next, look at the formation of Precipitate Precipitate An example of a reaction that occurs You may ask, which is the precipitate?

[00:28:12]The reaction that occurs How does barium chloride react?

[00:28:17]It reacts to form sulfuric acid.

[00:28:20]What happened after that?

[00:28:22]Barium sulfate was formed.

[00:28:25]That is our home.

[00:28:26]Precipitate. Plus what's left?

[00:28:28]What is there? Barium sulfate was formed. To HC L.

[00:28:34]Is it always a precipitant?

[00:28:36]We can give someone a downward gas.

[00:28:38]Always an upward arrow when coming Give it to me and then what should you do?

[00:28:41]Can you explain that?

[00:28:42]Why is that a change in temperature?

[00:28:45]Example: Why is it a formation?

[00:28:47]This is an example of precipitation.

[00:28:49]Just explain something, okay?

[00:28:51]Questions like this now.

[00:28:54]These three observations are asked If so, the next three observations Ask and you will do it accordingly.

[00:28:59]All observations are correct.

[00:29:02]Okay, I'll study the exam and pass it.

[00:29:04]Very good correct anto reaction s Dad, let's take a look at our next Coming up with the chemical equation What is a chemical reaction?

[00:29:16]Chemical equation for a chemical reaction What is written in equation form?

[00:29:21]What is a chemical equation?

[00:29:23]Equation Chemical Equation Symbolic Regression A chemical reaction is a chemical We are symbolic representatives of the reaction.

[00:29:33]Do it in forms of symbols and formulas.

[00:29:36]That is, reacting there Putting people's formulas or symbols Writing an equation formula What do we call chemical?

[00:29:44]What is called an equation is a Let's look at the example, S said it first.

[00:29:48]Example: Burning magnesium ribbon Example: Burning magnesium If you say it, it reacts to oxygen.

[00:29:54]What form did you take?

[00:29:56]A white powder magnesium oxide form Doing and then reacting What do people call us?

[00:30:03]We call it reactance.

[00:30:04]Always write on the left side.

[00:30:07]How many reactants are there in the binary?

[00:30:10]I'll add a plus and write it down. What should I do now?

[00:30:12]I'll give you six for writing the product.

[00:30:14]Can you give me a six or so for the product?

[00:30:16]The arrow's head must be faceted.

[00:30:18]Then what can I write for the product?

[00:30:20]On the right side, write how much product it is.

[00:30:22]If so, add a plus to that.

[00:30:23]What is the product that was created?

[00:30:25]This is how magnesium oxide is made.

[00:30:28]Basically a chemical equation So we write this equation It's called a word equation.

[00:30:34]So what is the easiest way to solve word equations?

[00:30:37]Of representing chemical reaction Using names of substances rather than Chemical symbols, that is, can be written in words.

[00:30:45]Reactants are products.

[00:30:46]Let's write symbols in words.

[00:30:48]In WordPress without using anything What is written is called a word equation.

[00:30:52]What you're saying is, look at this chapter.

[00:30:53]A type that can be expected The word equation is given by OffQuestion.

[00:30:57]Convert what you want to symbols.

[00:30:59]You will be asked to do magnesium.

[00:31:00]What can we write when we say MG?

[00:31:04]When you say "Okay, now oxygen" What can we write next?

[00:31:08]What is magnesium oxide?

[00:31:13]MG Apo converts like this Types of questions we have Clear enough to be expected.

[00:31:19]So what is a chemical equation?

[00:31:21]Said what is the word equation?

[00:31:24]So look, what is skeletal?

[00:31:26]Chemical equation, so here we are talking about Let's give a reaction then.

[00:31:30]It's coming to balancing then.

[00:31:31]Everyone, please pay attention.

[00:31:33]Coming to balancing then Magnesium is also on the reactant side.

[00:31:37]You can also see the count on the product page.

[00:31:39]How much magnesium is in the reactant side?

[00:31:41]There is only one here.

[00:31:44]How much is one on the product side?

[00:31:47]There's only one magnesium, right?

[00:31:50]How much oxygen is on the reactant side?

[00:31:53]There is oxygen, there are two of them, right?

[00:31:56]When you say that, two more products How many oxygen are there on the side? There is only one.

[00:32:02]So what happened here?

[00:32:04]The number of magnesium is on the left side.

[00:32:06]The right side is also equal, but oxygen Is the number equal or not on the reactant side?

[00:32:13]There are two oxygens but the product There is only one oxygen on the side.

[00:32:17]This means that this reaction is not balanced.

[00:32:19]We are dealing with unbalanced reactions.

[00:32:22]What is called skeletal chemical?

[00:32:24]Call it an equation, okay?

[00:32:26]Just the symbols of reactance there.

[00:32:29]That one reaction that is written in Or we can write that equation as skeletal.

[00:32:33]Call the chemical equation balanced.

[00:32:35]Simply put, it is not balanced.

[00:32:38]For reactions, we use skeletal chemical What is called an equation?

[00:32:42]A scalar chemical equation is a chemical equation.

[00:32:45]Equation EVSimulation Formula of the Rector's App.

[00:32:52]This reaction is participating in a reaction.

[00:32:55]of reactants and products Only symbols and formulas are used.

[00:33:00]What is not being done is not being balanced.

[00:33:02]This is a skeletal chemical equation now.

[00:33:06]Just look at some of the reactions already.

[00:33:08]Let's see if it will be balanced.

[00:33:10]Reaction is something we have said.

[00:33:12]The reaction is zinc in sulfuric acid.

[00:33:14]Zinc sulfate and hydrogen when added What happens first?

[00:33:18]What elements are there in it?

[00:33:20]Let's list out what there are.

[00:33:22]There is zinc, there is hydrogen, there is sulfur.

[00:33:25]There is oxygen, I wrote zinc hydrogen.

[00:33:28]What can sulfur oxygen do now, Left?

[00:33:31]Their side or reactant side Write oil on their product page.

[00:33:35]Let's write oil. Let's see how much zinc.

[00:33:37]There is oil on the zinc reactant side.

[00:33:41]No, there is no hydrogen here.

[00:33:45]Up there are two hydrogens, okay sulfur.

[00:33:49]How many are there on the reactant side?

[00:33:51]How much oxygen is there in sulfur?

[00:33:55]Apopha Oxygen is now on the product side.

[00:33:58]Look how many sinks there are in one.

[00:34:01]Is there zinc or sulfur?

[00:34:05]There is only one oxygen, four oxygens.

[00:34:08]Just look at the two hydrogens.

[00:34:11]Look at the numbers, you can see.

[00:34:13]Equal is the reactant side and the product side.

[00:34:17]The number of atoms on the side The number of elements is equal, so it is Balanced or not, already balanced?

[00:34:25]Isn't this because the numbers are equal?

[00:34:28]The reaction is already balanced, luckily.

[00:34:30]Don't you want to balance? Then balance.

[00:34:34]A well-balanced and already There will be equations and balance.

[00:34:38]There will be equations to be done then.

[00:34:39]We are an unbalanced equation.

[00:34:41]It is called skeletal chemical.

[00:34:43]The equation is clear, isn't it?

[00:34:46]Nokevich of the following Skeletal Chemical Equation Which of the following is skeletal?

[00:34:52]Chemical equation i.e. not balanced Just figure out what the equation is.

[00:34:57]There are numbers in all of this, right?

[00:35:01]So which chemical is not balanced?

[00:35:03]Equation or Skeletal Chemical Let's simplify the equation and say the number.

[00:35:08]Balance of nothingness Which equation is S option B?

[00:35:14]Gives no particular number.

[00:35:16]I didn't put it in, there was a reaction.

[00:35:18]The product is not just written down.

[00:35:20]Hydrogen and oxygen react together If there is water, which one is correct?

[00:35:24]Answer S option beta Isn't that simple, yes, skeletal?

[00:35:33]If we say chemical equation, it is balanced.

[00:35:34]Otherwise, just take it and write it down.

[00:35:36]Clears If this is the case, then look at the off-duty.

[00:35:40]Equation correction Chemical Equation Breakdown of Magnesium P Maybe ask for a reaction.

[00:35:48]The reaction that burns magnesium What is the skeletal equation? We already know All the written reactions Reaction of magnesium with oxygen Is it a type or a multiple type?

[00:35:59]Which of the following is skeletal?

[00:36:01]What is the equation you are asking about?

[00:36:03]How to choose skeletal chemical The equation is balanced, not up.

[00:36:07]Which one would be simpler to say?

[00:36:10]Just write the reactants and write the products.

[00:36:12]Don't think too much about it, it's a chemical.

[00:36:14]What is the skeletal chemical equation?

[00:36:16]Correct answer S Option B Magnesium Tablet That's the reaction we wrote +TMJ This is how you choose the skeletal equation.

[00:36:28]The question that has been asked is Let's see what skeletal is.

[00:36:31]Knowing what a chemical equation is Only a child can answer that.

[00:36:35]Very good document, just enough to write.

[00:36:36]S Okay, Dad, let's see.

[00:36:40]Getting to Balancing What is Balancing?

[00:36:42]He said that You must have seen the balance, right?

[00:36:46]It should be balanced on both sides.

[00:36:48]When the weights are equal, it is balance.

[00:36:50]Do the same with chemicals.

[00:36:51]Weight on both sides of the equation The weight of the reactants will be equal to two.

[00:36:57]The weight of the copus on the side is equal.

[00:36:59]What to do when it becomes a balance Let's look at the oxy atom olaboside.

[00:37:07]The number of elements on both sides is equal.

[00:37:10]It's a balancing act.

[00:37:13]Or let's call it the balancing process.

[00:37:16]Equation Balancer Chemical Equation That one that makes the balance equal I call the process balancing.

[00:37:22]Call it very important.

[00:37:24]Topic year, why balancing?

[00:37:27]Doing. Near the child.

[00:37:28]We always say to balance.

[00:37:29]Don't ask, why all this balancing?

[00:37:31]Why are you doing that balancing?

[00:37:33]Doing something we have learned to do What is the Law of Conservation of Mass?

[00:37:38]Conservation of Masmas cannabakrednabadiroida We can't even make Mars.

[00:37:45]Can't be thrown away cannabakrdanbdoei Chemical reaction up a chemical reaction I can't even get rid of the mass that's there.

[00:37:55]You can't even make a new one, okay?

[00:37:57]So what does that mean, how many masses?

[00:38:00]Was there that much mass of reactant?

[00:38:02]The product is just as mass on the side.

[00:38:04]There should be a reaction on the side too.

[00:38:07]Isn't it balanced? Then it's mass equal.

[00:38:09]If you want to be, what do you want?

[00:38:11]The number of elements must be equal.

[00:38:14]About the Law of Conservation of Mass What do we do according to What is the law of balancing?

[00:38:20]Conservation of Masmas canned food You can't even make a mask.

[00:38:27]How much can't be destroyed?

[00:38:29]Was there a mass?

[00:38:30]It should be in the product too, so how?

[00:38:32]It will happen if the same number is present.

[00:38:35]Only then will it be equal or lower.

[00:38:37]The Law of Conservation of Masses will be obeyed.

[00:38:40]What are we doing for that?

[00:38:42]Balancing what is being done is up.

[00:38:44]Why balancing?

[00:38:46]Doing this to obey Always obey that law.

[00:38:49]We must have done it then.

[00:38:51]Let's see.

[00:38:52]So let's do the balancing.

[00:38:54]Let's see how it goes.

[00:38:55]He gave a reaction. Then you step.

[00:38:57]We have to go step by step. Okay then.

[00:38:59]Count it first. Number Let's see if it's equal or balanced.

[00:39:03]Let's check. So we are all ready.

[00:39:05]I said here is a magnesium here is a Magnesium here two oxygen here one What do you need oxygen for? Magnesium Allready Equal to me is the number of oxygen.

[00:39:13]It should be done. Oh, there's oxygen here, both of them.

[00:39:16]It's the same beyond. So that's equal.

[00:39:18]If you want to make it, what do you need? What I need you to give me your number.

[00:39:23]Okay. Put the number in the balancing.

[00:39:25]You can give it. Okay, but where?

[00:39:27]You can only give it.

[00:39:29]What is that substance on the left side?

[00:39:31]It is only placed on its left side.

[00:39:32]You can only give. Here I am.

[00:39:34]Can I put it in? No, possible.

[00:39:36]No. So where to put it?

[00:39:38]Can we? Where to put it?

[00:39:40]Is that possible? Where? Yes, magnesium.

[00:39:43]Over here. Where should I put it?

[00:39:48]One second.

[00:39:51]I put two here, what happened?

[00:39:54]Two magnesiums but beyond There is no one else, there is also oxygen.

[00:39:58]Who is with you, Father?

[00:40:01]This oxygen also applies to anyone.

[00:40:04]I'll put it here if it applies.

[00:40:06]Magnesium is two, so no one is two with it.

[00:40:09]So what if it's two with oxygen?

[00:40:11]What should I do?

[00:40:14]That is, magnesium reacts with oxygen to form its Isn't it the same with magnesium?

[00:40:20]It's two, but how much magnesia is there on this side?

[00:40:22]There is only one magnesia, what is it?

[00:40:24]If you put a "to" here, you should do it.

[00:40:26]Couldn't you get it? So what's the number?

[00:40:29]If it is not equal, then it is equal.

[00:40:31]Try to make it equal to To make oxygen equal to I put two here and gave them two.

[00:40:36]Anyone can use oxygen.

[00:40:38]Oxygen also applies to magnesium When you divide into two, no one is divided into two.

[00:40:42]Okay, then, magnesium, two.

[00:40:45]Magnesium is divided into two here, so we Here too, it should be divided into two parts and cleared.

[00:40:50]Okay, so where are you?

[00:40:53]Let him go near you.

[00:40:55]Otherwise, I will miss it there.

[00:40:56]Then came the question of balancing.

[00:40:58]You can check it yourself afterwards.

[00:40:59]Is the written answer correct or not?

[00:41:01]Let's check the number.

[00:41:02]If it is correct, then the balancing is correct.

[00:41:04]Okay, so if the number is not wrong.

[00:41:06]If the number is wrong, somewhere Okay, about the mist.

[00:41:10]Be careful and think carefully.

[00:41:13]To think about something else The order was made correctly.

[00:41:17]Exactly after that You can correct it.

[00:41:21]Okay, okay, if that's the case, then the next one.

[00:41:24]Assertion and Reasoning by Looking at the Question The question is the balance.

[00:41:28]Chemical Equation for the Action of Stream On one means stream means water vapor Reaction that reacts with iron Which gives 3A+FAETAETFA+FAETA Okay, what's the reason now?

[00:41:44]What is given?

[00:41:46]Of Conservation Omasga Good for a Chemical Equation 2021 for Board Exam Okay, that's the question that was asked.

[00:41:53]So, give a balanced reaction.

[00:41:55]The chemical equation is given.

[00:41:57]What do you mean by that?

[00:41:58]Should I check if it is balanced?

[00:42:00]There are three ions on this side.

[00:42:03]On the other hand, there are three ions.

[00:42:05]Okay, so hydrogen is like this.

[00:42:08]How does hydrogen number come into play?

[00:42:09]Count it.

[00:42:13]Don't add, multiply.

[00:42:17]Hydrogen There is hydrogen everywhere.

[00:42:23]So hydrogen is equally next.

[00:42:25]If you put oxygen here, Is there anyone else out there who knows?

[00:42:30]Applicable for oxygen How much oxygen is there down here?

[00:42:37]What can you see for a fourth?

[00:42:39]Oxygen is all the correct numbers.

[00:42:43]Isn't it the elements on the left side?

[00:42:45]The number of the element on the right side The number is also equal, so this is correct.

[00:42:50]Assertion is correct and reason is balanced.

[00:42:52]What does the Law of Conservation of Mass say?

[00:42:55]Holes are good for a chemical reaction now.

[00:42:57]Isn't what you've given balanced?

[00:42:58]What can be said about the Law of Conservation of Energy?

[00:43:01]Mass Oh, he's doing it, so what's up?

[00:43:06]True is true and true is the correct explanation.

[00:43:09]Is this really good? Is this correct?

[00:43:12]Expansion of an up correct answer Both are true.

[00:43:17]Check if both the corrections are correct.

[00:43:20]Please explain it.

[00:43:22]Check it out, okay, then in this part.

[00:43:25]Nuc Assertion and Reasoning Questions Let's wait a little longer.

[00:43:28]If you try balancing, you will suddenly Should we speed up? What should we do?

[00:43:33]Let's see, do it quickly then.

[00:43:35]Hydrogen and oxygen react together A reaction that produces water So what do you need, one by one?

[00:43:42]Let's see what we follow here.

[00:43:43]The method is called hit and run.

[00:43:46]Please enter the method number and check.

[00:43:49]Do it okay if it's not correct.

[00:43:51]Please enter the number again.

[00:43:53]Do the hit and trial method up.

[00:43:54]Let's see how much hydrogen is here.

[00:43:57]Two hydrogens are on the other side.

[00:44:01]When you say that, it means two hydrogens.

[00:44:03]Oxygen How much oxygen is there on this side?

[00:44:06]Two oxygens on this side or one oxygen on that side?

[00:44:09]Okay, so who is not balanced?

[00:44:12]Oxygen balanced, not hydrogen balanced Is oxygen not balanced here two There is oxygen, but there is only one oxygen.

[00:44:18]What do I need to do with this oxygen? I need to split it into two.

[00:44:21]So where did you put my number?

[00:44:22]I can give it to you, then I will.

[00:44:24]I put two in and then I put two in.

[00:44:26]When I gave it, it split into two oxygen molecules, but Whatever happened to this hydrogen number?

[00:44:30]Okay, here it is, 2 hydrogen atoms.

[00:44:35]If you give me the number, it will be shared with two people.

[00:44:36]Not applicable, so where do we put the number?

[00:44:38]Do you want to give it to me? Go there and get closer.

[00:44:40]So here, both become 2 plus four hydrogens.

[00:44:43]So what do you need on the React side?

[00:44:46]What do you need to do to make hydrogen? Just two things.

[00:44:48]Just give it to me and it will be clear. Very good.

[00:44:51]2nd place Gives 2nd time after we're done Please check again. Is this correct?

[00:44:57]Did you do the right thing? Did you miss anything?

[00:44:58]Check again to make sure it hasn't happened.

[00:45:00]Please correct the number.

[00:45:01]If it is, it means your Balancing correctly means Okay, so the correct answer is 2.

[00:45:08]Gives 2 takes, what's next?

[00:45:11]Look +2gs Eight So there's an ion over there.

[00:45:19]There are two irons, one on this side and one on that side.

[00:45:23]Isn't that the same thing balanced? Oxygen here?

[00:45:26]Two oxygens, three on the other side.

[00:45:29]It's oxygen, but it's not balanced.

[00:45:32]The oxygen is also not balanced, okay, dad, here.

[00:45:35]What is one ion and two ions on this side?

[00:45:38]What should I do here? I am a two-faced person.

[00:45:40]I gave it to him and he said it was Iron's correct answer.

[00:45:43]Two ions here and two ions there.

[00:45:45]Now oxygen here, two oxygens there.

[00:45:48]What is the number of three oxygens?

[00:45:51]What can be done to make it equal?

[00:45:54]Multiply this by three.

[00:45:56]Multiplying by two This is oxygen, and here is 2 of it.

[00:46:03]It's oxygen, but I put it here.

[00:46:05]What happened? Iron's number has changed too, hasn't it?

[00:46:09]So what is the number of Ion now? 2 Itufanala How many irons are there on this side of the ion? Two irons.

[00:46:16]There is nothing to do, just change it.

[00:46:18]Let's make it four.

[00:46:20]Clear yes, where did we put the number?

[00:46:22]Go to him, will you give it to him?

[00:46:25]Okay, because there is change.

[00:46:26]If so, please act accordingly.

[00:46:28]Done, got it So, small examples.

[00:46:34]Go big first.

[00:46:36]After taking the big one It will be difficult then for you I have to say, balance is incredibly tough for me.

[00:46:40]If you don't get it, then what do you need first?

[00:46:42]Do small, small examples.

[00:46:44]Slowly slowly big big Just pass the exam and you'll be clear.

[00:46:49]Okay, that's very good.

[00:46:53]Now look, I did this.

[00:46:54]Look, wait a minute.

[00:46:56]GivesEtA+T GivesEtat Here is an aluminum reproduction.

[00:47:06]Two aluminum on the side Aluminum is not balanced anymore, is oxygen?

[00:47:11]Here two oxygens, there three oxygens.

[00:47:14]So, oxygen and balance are not the same for both people.

[00:47:16]Let's balance it out, here are two.

[00:47:19]Aluminum is an aluminum here. What is it?

[00:47:21]I should put two here.

[00:47:23]Okay, two things about aluminum.

[00:47:25]Aluminum two aluminum now oxygen Case that here two oxygen here three What can I do with oxygen? It only takes three Let's multiply this by Let's multiply by two first.

[00:47:37]The same method I used is six.

[00:47:40]Here is 2, three, six as oxygen.

[00:47:42]It's oxygen, but I put two here.

[00:47:45]What happened when you gave it?

[00:47:46]The aluminum number has also changed, okay?

[00:47:48]How much is aluminum now?

[00:47:52]How much aluminum is there on this side? Two There's aluminum, what can I do with it?

[00:47:56]Change it and put four in it, okay, dad?

[00:47:59]What is our correct answer?

[00:48:05]Gives 2nd place Once you get it like this, check again.

[00:48:10]Do the numbers.

[00:48:11]Okay, if that's correct.

[00:48:13]Or correct number equal number If you got your answer Okay means okay very Okay, that's the correct answer.

[00:48:23]Now look at the next one, Wi-Fi balance.

[00:48:27]What is a chemical equation?

[00:48:29]A question after elaboration You may ask for three marks.

[00:48:32]The question is not only balance but also three The question is being asked to Mark.

[00:48:36]A question asked in 205 Balance between the two Chemical Question Why is a chemical Why do equation balancing?

[00:48:44]Law of Conservation of Mass So we have to obey.

[00:48:48]I wrote the same explanation as before.

[00:48:50]The can is a credenza.

[00:48:54]Law of Conservation of Mass i.e. Total The total mass on the reactant side is The total mass on the product side is equal to Therefore, the Law of Conservation of Mass is obeyed.

[00:49:04]When will it be equal to reactant?

[00:49:07]The number of elements on the side and the product The number of elements on the side is also equal.

[00:49:10]When it comes to you, you will be satisfied.

[00:49:13]Conservation of Mass Very Good Okay Apo You must write the answer according to the mark.

[00:49:18]Okay, explain the answer to you.

[00:49:21]What to do Let's have a reason in our language.

[00:49:26]Or that one answer explanation According to the mark, it can be done.

[00:49:29]Just done.

[00:49:32]Which law is the balance of a chemical equation?

[00:49:35]Asked about the conservation of mass So, we shouldn't forget Law's name anymore.

[00:49:40]Balance the following chemical equation.

[00:49:42]Given chemical equation Balancing is also a question, then.

[00:49:44]That's why there are three questions.

[00:49:46]Three marks, first question one.

[00:49:47]Marks: The next question is one mark.

[00:49:49]Okay, one mark for balancing.

[00:49:51]You should write the answer accordingly.

[00:49:53]Look at this reaction balance.

[00:49:55]Let's see what we can do.

[00:49:57]A little more and it became a big reaction.

[00:49:59]Don't be afraid, we used the same Let's follow the method, then sync here.

[00:50:04]How many sinks are there here? One sink here.

[00:50:06]What did I do with three sinks?

[00:50:09]Okay, yes, that's three.

[00:50:12]There is a sink there, there are three sinks here.

[00:50:14]Now look here, how many H's there?

[00:50:17]How much do you have to look at everything inside?

[00:50:20]Is there a product that has H count on it?

[00:50:22]Okay, then here it is.

[00:50:24]What should I do here?

[00:50:27]Multiply by three here.

[00:50:28]Let's multiply by 2. Okay, 2. It's okay.

[00:50:31]It became hydrogen, and it became hydrogen.

[00:50:34]Okay, I just put the number here.

[00:50:36]This number given is also for the person on the other side.

[00:50:38]It's a plague, okay, who's there?

[00:50:41]There is phosphate there, what do you do there?

[00:50:44]Separate each atom How much phosphate should be considered?

[00:50:49]Just look at how much phosphate there is.

[00:50:51]Yes, if you put two here, it's two.

[00:50:52]There is phosphate in the apterous.

[00:50:55]How many are there? Two times.

[00:50:57]And didn't you see the bracket?

[00:50:59]There are two outside, which means there are two.

[00:51:02]There is phosphate, okay, here it is.

[00:51:05]Two phosphates here and two here Is the phosphate balanced? Let's see.

[00:51:10]Three sinks, three sinks. 3 * 2 * 3 Six hydrogen six hydrogen two phosphate Two phosphates are balanced, okay?

[00:51:21]So, consider each separately.

[00:51:22]Doesn't. Now sulfate phosphate When it comes, it becomes a group.

[00:51:25]Just consider it. Together with it Just count it. Okay, clear.

[00:51:29]Isn't it? S is the correct answer.

[00:51:31]Look at me+ 2Ethpafa Give me a call.

[00:51:37]Twispada Clear or okay? Is it easy?

[00:51:43]What is chemical reaction balancing?

[00:51:46]You will get some equations, right?

[00:51:48]Some equations from the website You can balance it all out.

[00:51:52]The more we balance, the more It will be easy, okay, we have a lot of equations.

[00:51:58]Look at what you did, it was so fast, so fast.

[00:51:59]Will come Okay, then won't you follow me?

[00:52:03]Take questions and balance.

[00:52:05]Because a paper without balancing There will be no sure question.

[00:52:09]Will take reactions then?

[00:52:11]Balance it and do it.

[00:52:13]Try it again, okay, balancing.

[00:52:15]What is the reaction once you get speed?

[00:52:17]Even if you give it, you will have balance.

[00:52:18]Is it possible to do balancing?

[00:52:21]Is it easy?

[00:52:23]Is it?

[00:52:25]Do you get balancing?

[00:52:26]A few answers to do.

[00:52:28]Isn't it the answer to everyone's question?

[00:52:30]I'm checking if it's correct.

[00:52:33]Okay, what can I do to balance?

[00:52:35]If you get it balanced What to do next: Focus on speed Do it and strike a balance.

[00:52:40]Can't we just sit for a while?

[00:52:41]Should we write the rest of the answers then?

[00:52:43]What can I do to increase speed?

[00:52:44]Be careful, it will be wrong when you increase speed.

[00:52:46]No, okay, then yes, then yes.

[00:52:50]Accordingly Forgot to put the hole in two.

[00:52:57]What is S?

[00:53:01]Put two outside the brackets twice.

[00:53:04]You have to give it to me, right? Okay, okay.

[00:53:08]Look, there's another question.

[00:53:09]Look, you're using the IdentifyP QR code.

[00:53:12]There is no such thing as a balanced reaction.

[00:53:16]How long has it been since you gave a reaction?

[00:53:18]Find out how much Q is.

[00:53:19]Find out who is who.

[00:53:20]Find out after balancing.

[00:53:21]Just write down the numbers there.

[00:53:23]That's all, it's not a big question.

[00:53:25]So what do you do with that reaction balance?

[00:53:27]Let's do it, let's have a reaction.

[00:53:29]Let's write it down. PBNO3 PBETH Twice Givespibaedupaota This is the reaction, don't look at it.

[00:53:42]Balance it with the same method we learned.

[00:53:44]How many PB are there to balance here?

[00:53:47]A PB here is a PBPB correct.

[00:53:50]Now, what have we considered together here?

[00:53:53]How many times have you been here?

[00:53:56]How many P's are there outside the bracket?

[00:53:58]There are two OKs and two N's over here.

[00:54:01]Look at that nitrogen here and there.

[00:54:04]Oxygen should also be given in split doses.

[00:54:06]All three products contain oxygen, so What should be done? Separate counting should be done.

[00:54:10]Okay, so how much nitrogen is there here?

[00:54:12]Look, what's here?

[00:54:14]If you say that the life is twice, then nitrogen It applies to oxygen too.

[00:54:20]How much nitrogen is there in these two?

[00:54:22]Nitrogen How much nitrogen is there? Check the total.

[00:54:25]Do this only contains nitrogen There is only one nitrogen, so what?

[00:54:29]I should do it, I'll break it into two nitrogens.

[00:54:32]Okay, so what about nitrogen?

[00:54:35]Okay, next up is oxygen, oxygen.

[00:54:38]Lie down and take all the oxygen.

[00:54:40]We should consider it okay then.

[00:54:42]How much oxygen is there here?

[00:54:45]It's Twice, so it's both.

[00:54:47]It is not possible to multiply.

[00:54:50]The total amount of oxygen on the reactant side is There is oxygen, just look at the product page.

[00:54:55]Here is an oxygen, look here, 2E tough.

[00:54:59]Look at the oxygen here.

[00:55:02]Those two oxygens Look at that.

[00:55:07]S What is Look, there's an oxygen tank here.

[00:55:17]Here is one oxygen, here is two oxygens.

[00:55:19]Here, here, four oxygens, here, two How much oxygen is there in total? Yes.

[00:55:24]Did you get the option? That's really good, all of a sudden.

[00:55:26]Well, then we did this.

[00:55:28]According to the number given What do you need? You are the correct PQR.

[00:55:34]That should also be written on the order itself. P It says "to" and "q" says "to".

[00:55:39]The word "ar" means "four". Okay.

[00:55:43]Then balancing as you normally do.

[00:55:46]Do it. What do you want? That number Check that it is correct.

[00:55:50]We have got the balancing correct.

[00:55:52]Will do. You will make mistakes when you take it and write it down.

[00:55:53]So, the answer we gave specifically If it is correct, then Don't get it wrong, okay, option S is the answer.

[00:56:01]This is option 8.

[00:56:06]Twice gives 2pbuffat Balancing whether you have oxygen Take the numbers and write them down.

[00:56:15]Choose the correct option.

[00:56:17]Then when choosing the option Don't make a mistake, balance it properly.

[00:56:20]It's time to fix it up there.

[00:56:22]Don't break your leg with that, okay?

[00:56:26]You may also have questions like this.

[00:56:28]It's to be expected then.

[00:56:29]How about if you have learned balancing?

[00:56:31]Ask me anything, Sam.

[00:56:33]You can write the answer in the pattern.

[00:56:36]Look, that's all. Okay, that's all.

[00:56:39]Balancing S Okay, so one thing.

[00:56:42]Do you do these three reactions?

[00:56:46]What is the balance after the note is down?

[00:56:48]Please leave a comment if you have an answer.

[00:56:50]Let me know in the box. Okay, let me see.

[00:56:52]Who is correcting who?

[00:56:54]Three answers are being corrected.

[00:56:56]Let's see if S then Everyone, three reaction notes down.

[00:56:59]Just do it and then balance it.

[00:57:02]Everyone wrote in the comment box.

[00:57:04]Okay, let me know, then balancing.

[00:57:07]Is it clear or is it easy for everyone?
