[00:09:21]So make use of it.

[00:09:24]Okay. Clear? Yes. Hi. Hi.

[00:09:30]Perfect. Perfect my dear. So, so first question of the day.

[00:09:45]So, physical chemistry first question.

[00:09:48]Here we go.

[00:10:02]subject related question.

[00:10:18]So please keep this in mind. Yes.

[00:10:23]Promise. Promise my dear.

[00:10:26]Answer the number of moles of the number of moles of KCO3 needed to produce 67.2 liter of oxygen at STP. Yes. 67.2 two of you know number of moles of K3.

[00:11:04]Okay. Okay.

[00:11:09]buffering.

[00:11:11]So first of we all know number of moles of oxygen is equal to given value 67 Right. So given value 67 given value divided by 1 volume 1 volume 1 is equal to we know 1 is equal to 22.4 L given volume 22 22.4 L number of moles of oxygen here is three moles.

[00:12:22]As per this equation for three moles of oxygen, you need 2 moles of K3.

[00:12:35]Answer. Answer. What is the right answer?

[00:12:46]2 moles of K3 and so option B is the right answer.

[00:12:51]Option B is the absolute correct answer.

[00:12:55]Ma'am, I'll just change it to my mic. I just change it to my mic.

[00:13:15]Okay.

[00:13:34]Okay.

[00:13:39]Yes. So now is it clear? Now is it clear?

[00:13:59]buffering.

[00:14:06]But yes, so we will start with the first question once again. Okay.

[00:14:21]question the number of moles of K3.

[00:14:33]So the first question of the day the number of moles of KCL needed to produce 67.2 L of oxygen at FTP reaction of you know K3 of first step number one is to convert liter to number of moles. Number of given volume divided by m volume 1 volume it is 22.4 4 lit given volume 67.7.

[00:15:48]What is the answer my lord? It is 67.2.4 4 1 67.3 Th three times and so 3 moles of oxygen three moles three moles three moles three moles of oxygen two moles of answer is option B two option B2 the volume of 0.2 2 m H2SO4 required to neutralize 50 ml of 4 m4 Ma volume of 0.2 m of H2SO4 required for 0.4 m of ya.

[00:16:52]So first in the entire reaction the basic reaction is H2 SO4 plus 2 N A H gives 2 H2O O plus 2 N A2 S O4. Correct. Plus Na2 S4 number of moles of Na H. Number of moles of Na.

[00:17:48]Number of moles of Na.

[00:17:50]We know number of moles is equal to volume into marity. Volume into marity 50.4 50 into 0.4 44 version 0.050 into 0.4.

[00:18:39]It is none other than 0 to clear right number of moles of Na number m1 v1= m_sub_2 v2 m1 v1 0.02 Right.

[00:19:15]0.02 m_sub_2 is 0.4.

[00:19:22]So 0.4 into v2.

[00:19:27]What is the answer? Final answer it is either 0.2.0 final 25. So option A is the right answer. Option A is the absolute correct answer. My lord right the percent by mass of hydrogen in water okay percent by mass percent by mass percent by mass mass by mass percent of hydrogen in water percent by mass2 that is that is 2 g of hydrogen plus 16 g of oxygen correct hydrogen value it is number of given value of hydrogen which is 2 divided by total value total value 2 + 16 is 18% into 100 approximate 11.1 correct 11.1 forward one times one forward one times 11.1 option B is the right answer. Option B is the absolute correct answer. Clear question how many g of CA3 are needed to obtain 5.6 Six liter of CO2 at STP.

[00:21:42]Same first question.

[00:21:54]Yes.

[00:22:00]This is B what I have said has happened in 2025 now 2024 last before that I was working with multiple other institutes. So 2025 questions 2026 out of 45 chemistry questions 40 questions most expected history will follow itself not over confidence but hard work full night.

[00:23:02]So for sure you will get questions only from here.

[00:23:08]Okay. Yes. Thank you. Thank you Vishali.

[00:23:14]Thank you so much my dear.

[00:23:17]Yes. Thank you. Thank you Rama.

[00:23:20]Hi. Hi Kaneskar. Welcome on board.

[00:23:23]SO WHAT IS THE ANSWER for this question my dear? How many grams of 3 are needed to obtain C3 are needed to obtain 5.6 62 convert to from lit to number of moles.

[00:23:52]We know number of moles of CO2 is equal to given mass divided by molar mass.

[00:24:02]Hippo mass of C2 oxygen or oxygen 16 oxygen 32 44. So 44 g of C2 mass is 44 sorry.

[00:24:28]So given volume divided by molar volume because we know volume for any substance is 22.4 L given volume 5.6 L given value. So it is 5.6 L.

[00:24:54]Which means what is the right answer my lord?

[00:24:58]What is the right answer? The answer is 0.25 mole of CO2.

[00:25:07]One mole of CO2 of Ca3 0.25 of CO2 0.25 25 of Ca 0.25 of C A3.

[00:25:44]What is the right answer? My lord calcium carbonate 100 g correct 0.25 0.25 into 100. The answer is what? The answer is absolutely option A. A for a for a for and so option A is the right answer.

[00:26:11]Okay.

[00:26:18]So option A is the right answer. Option A is the absolute correct answer.

[00:26:39]Okay.

[00:26:46]Okay. 21st 23rd I will come to each and every learning center. Okay. So yippo yippo the energy required to remove the electron from hydrogen atom in ground state is what happened with everyday it will happen it will happen I take like 3:00 4:00 5:00 so it always happens with me because it is a lengthy process I cannot trust anyone on that okay so the question the energy required to remove the electron from hydrogen atom in ground state in the question.

[00:28:09]So it is very very important for you to focus on these questions. Right?

[00:28:17]So always remove the electron from atom in ground state. Ground state which means the answer is even.

[00:28:41]If they ask what energy it has, it is minus. If they ask what energy it needs needs, it is plus a is the right answer.

[00:28:51]A is the absolute correct answer.

[00:28:59]What is the energy required?

[00:29:03]Answer should be in request.

[00:29:32]Right.

[00:29:34]How many spectral lines are emitted when a electron and hydrogen atom moves from ground state?

[00:29:57]You don't have to worry.

[00:30:00]Okay? Focus on the class. Focus on the class. Focus on the class.

[00:30:26]n into nus1 / number of lines emitted from this line to ground state this line to ground.

[00:30:38]So either answer value is none other than five correct 5 into 5 - 1 by 2 which is 5 into 4 by 2 which is 20 by 2 which is 10 option say 10 is the right answer right answer is the absolute correct answer my Okay.

[00:31:16]Super super super.

[00:31:31]Okay.

[00:31:42]The question the orital with quantum numbers n = 3, L = 2 and M = -2 is= value.

[00:32:06]Next = 2 L= 0.

[00:32:12]It is S orital one in the P orital. Two are in the D orital.

[00:32:25]2026 important important question.

[00:32:40]Please focus on this. L= 2 L2.

[00:32:45]Then it is D orital.

[00:33:04]It can be either dxy, dyz, dz x, dx² - y² and dz² option B is the right answer clear. So yes for snake correct answer right minimum five questions minimum question uncertaintity principle Thank you. Thank you.

[00:34:07]So haz delta x and momentum momentum delta p or m delta v So that is why delta x m delta v is greater than or equal to h4 and velocity. for Electim.

[00:35:26]Answer. And so option B is the right answer. Option B is the absolute correct answer.

[00:35:34]Super question.

[00:35:37]B's law.

[00:35:40]B's theory or atomic theory in the Henber uncertenity principle. follow yes or no in the comment section.

[00:36:01]So yes, fire no heart.

[00:36:11]Let me know in the comment section. Let me know in the comment section. Atomic theory Hazenberg's uncertainty principle follow Hi hi welcome welcome on board Haria welcome welcome welcome super super super hot oh So yes yes yes the answer is full heart connection.

[00:37:09]And yes, yes, whatever you guys said is correct.

[00:37:28]The answer is no. And this concept is super duper important my so clear.

[00:38:24]Sulfur. Group 16.

[00:38:27]Group 16.

[00:38:31]O C T which means O for oxygen correct S for sulfur S for selenium T E for toum P O for ponium. So OCidation number 16 valence electron is six and valence electron max.

[00:39:12]Welcome welcome welcome on board dragon.

[00:39:15]So f F correct the ruin.

[00:39:28]So what is the angle?

[00:39:31]What is the angle?

[00:39:42]Equatorial angle is 90°. Axial angle is 180°.

[00:39:48]Both axial in equatorial. Option D is the right answer. Option D is the absolute correct answer. Super super super dam right answer. Okay. Okay. Clear.

[00:40:06]Yes. SO in super oxide ionoxide example H2O2 order what will BE THE BOND ORDER MY LORD?

[00:40:27]What will be THE BOND ORDER MY LORD?

[00:40:31]O2 it is none other than bonding number of bonding minus number of antib-bonding.

[00:40:52]So first one up one star sigma s two electron then two sigma yes two two star sigma yes two bonding antib-bonding Antibondus the answer is what 10 - 7 is 3 MY LORD 3X 2 IS 1 BY 5 MY LORD 3x 2 1 by 5 1.5 option three is the right answer please implement important concepts. Okay. Fine. Yes.

[00:41:57]Among C2 H6, C2 H4 and C2 H2 C bond length increases in the order increasing order.

[00:42:11]Always remember bond single single attraction between two atoms is minimal.

[00:42:23]Double bond attraction triple bond whenever force of attraction happens.

[00:42:34]This attraction is inversely proportional to bond length. attraction increase.

[00:42:43]In other words, increase bond order increase.

[00:43:01]C2 H6 is an algen.

[00:43:05]C2 H4 C2 H2 based on the number of bonds and so and so C2 H6 should be the um you know C2 H6 having the smallest bond order should have the largest bond the correct answer is what the correct answer is option K first okay clearer Ma'am voiceh.

[00:43:49]But anyways, I'll just inform the team.

[00:43:51]Okay. Don't worry. Don't worry. Don't worry.

[01:15:40]So, Thank you. Thank you my dear because because Okay 180 likes 180 marks. Okay. Relative lowering of vapor pressure equals what?

[01:16:26]Relative RV lowering of vapor pressure. Now it is delta P. But relative lowering of vapor pressure of vapor pressure which is Option B solute.

[01:16:58]The right answer is mole fraction of solute. And so and so option A is the right answer. Option K is the absolute correct answer.

[01:17:08]Super super. So and so. Option A is the right answer. Option E is the absolute correct answer.

[01:17:15]Which property is independent of nature of solute particles in dilute solution?

[01:17:22]property nature of solute.

[01:17:27]Super easy question. Super easy question. Let me know the answer for this.

[01:17:44]A form.

[01:18:00]Right answerative property. The property which one depends on the number of soluteity property. It does not depend on It does not depend on nature of solute.

[01:18:45]Okay. So nature of number of solute and so option B is the right answer.

[01:18:58]Option B is the absolute correct answer.

[01:19:01]So okay, we always remember whenever you have and electrolyte stronger weaker Whenever the strong base I value is equal to number of ions number of ions example let's say NaC Na K value Na plus CL minus value H+ or SO4 2 minus H+ or SO4 2 minus. So total number of ions total number of ions 2 + 1 3. Either way I value H I value. Very good. VERY GOOD. VERY GOOD.

[01:20:56]Total number of value for HCL is said to be two H+ example ura weak electrolyte I glucose weak.

[01:21:35]Clear. Very good. Very good my dear.

[01:21:41]Osmotic pressure.

[01:21:48]If in caseh Yes. Yes.

[01:22:18]So for concentration I formotic pressure.

[01:22:40]Yes. Yes. Is it clear? Is it clear? Hi So the reaction is t = 3 is to 4 and t half = 2 is to 1 reaction Hi Promonry. Welcome, welcome on board my dear. Welcome, welcome to the family.

[01:23:28]question 3x4 3x4 75% t 50% 50% value one 75% value 100 units and the value half you should Hello. Hello.

[01:24:32]Want to go to now? Okay.

[01:24:47]Tre 503 T3.

[01:25:13]Hi. Hi JK. Welcome on board my dear 75%.

[01:25:24]And so and so the correct answer is Yeah.

[01:26:03]The rate constant of reaction at 27° is K.

[01:26:09]37° activation energy now. Okay.

[01:26:54]As I can see here, the video is perfect.

[01:26:58]Okay.

[01:27:02]rate constant at 27° K, 37° 2K based on temperature dependence, rate will double for every 10° rate doubles for every 10°.

[01:27:25]Correct. So activation energy activation energy will depend on both both temperature and K value and option C is the right answer.

[01:27:54]So Seriously guys, I don't know what is happening here.

[01:28:05]I'm sure But focus on the class. Okay. Focus on the class. First order reaction 50% completion 30 minutes. Then for 99% completion I'll check. I'll check my dear. I'll check and I'll back up.

[01:28:59]Manga focus on the class. Focus on the class. Rea hi my dear welcome on board.

[01:29:05]So you for a first order reaction your 50% completion takes 30 minutes 99% complet for for 99% completion all you have to do is 6.6 very easy 99% 6.6 or 6.64 exact 6.64 99% completion and so 6.6 into t is 30 minutes correct. So t half is 30 minutes multiply answer it is nearly 199 minutes and so 200 is the right answer.

[01:30:02]Clear? Hi Karthik, welcome back. Welcome back my dear. Answer. Answer. Option D is the right answer. Option D is the absolute correct answer. My lord.

[01:30:14]Number of moles of electrons transferred when one mole of CR27 2 minus is reduced to CR3 plus.

[01:30:26]Easy. First number of moles of electron transfer C2 minus 2 oxygen oxygen oxygen -4=2 -2 + 14 -2 + 14 - 2 + 14 you will get what you will get 12 2 x 12 then x value is equal to 6 which means chromium 6 obviously 3 For one mole of C2 you need how many moles of electrons?

[01:31:35]You need three moles of electron. Clear? Clear?
