Solid State || Class12th Chemistry || Numericals Chapter 1 #numericals @a2zpractical991

Hello Bacchu, how are you all? I think you will have a very great life. You will surely keep an eye on the A to Z practicals. So, Bachchu, you must know that My chapter 1 of 12th Chemistry It was a solid state, all its parts. I have finished it, and very well indeed. and everything else in a very digital way I have taught you this here, child. The last part is basically numericals. because numericals is from the chapter Exams come too frequently. Because this is very, very important. So you're going to leave like this Because it is fixed for 3 marks Numericals is the chapter from this Not for 3 marks, if the big ones don't come, then... They definitely give the 2 marks for the smaller ones. We will not let this go; we will see it through to the end. So, Bachchu, today I'll start. Your chapter 1 solid state numericals I've already finished reading through this theory. So, let's begin, I'm starting right away, no delay. You don't waste time, do you? To solve the numericals of this chapter Some things are there that You should know like centimeter from What will you do if the conversion takes place? After that, some point shifting You should know if you know that point shifting those numerics You can solve it very easily. So, main aapko pehle Let me tell you some basics. Now we'll jump to the numericals. Alright What are the basics? What are the basics? We see it What are the basics? He will come again someday. picometer to You will come to me someday. 1 picometer is To convert centimeters What will you always have to do for yourself? Whatever thing is given to you in picometers milli lo aapko 4 picometers to I want to convert centimeters Then what will you have to do? first picometer To convert meters To convert picometers, what unit should be used before? Measure me To convert picometers to meters We multiply by 10 raised to the power of minus 12. Alright, let's do it then. 4 times 10 to the power of minus 12 Then in which answer will your answer appear? It will come to me. See, Bachchan, do we need the meter or not? I need it in centimeters. if you got it in meters from the meter Listen to Bachchan from the money centimeter for buying What do we do with it? Multiply by 100 10 squared To convert meters to centimeters 10 squared All right, that's it for picometer 2 Picometer has become 2K. centimeter to convert Convert this to centimeters. The other thing is, if you want to do this annually, you can do it easily on an annual basis. This is minus twelve, this is plus two, so what's your answer? Four into ten rest to ten 4 × 10⁻¹⁰ You've got these things clear now. There's one more thing, now you know this too. Or if you don't know, I've already told you myself. There is a point shifting, and you should be aware of it. If you know point shifting, you can do it very easily in the Aizilie way. Let me also tell you a few points that might shift your perspective. So that when we teach numerics So you don't have any problems at all with it Also check out how to perform point shifting. Listening with meditation 6700 × 10⁻² Look, how you can perform a point shift Maloo, you have been given a point here So if you're taking the point to the left side, you'll go that way. 66.00 Shift the point one digit to the right. Let's shift to the side. You will always add one more to this. 6700 × 10⁻² It will become 3. Take a look at one more 560.06 × 10⁻² So if I shift the point one digit to the right So how will this look: 56.06 × 10⁻² What will you do? Will you do Plus One? If you shift the point one digit this way So what will you do, always plus one, so three, so how much will it become? But if the children shift the point together with you You will always subtract one from it. You're right, if you take it along, what will you always do with it? Like minus one, it gave you something like that 600 × 10⁻² 60.001 × 10⁻² So if you shift the point one digit this way So, what will you do here? Will you do minus one? 60.001 × 10⁻² I'll shift the point over谝 So what will this become 10-2-1 I mean, you've now understood it, right? Move the point one digit to the left. What will happen to 360.1 × 10⁻²⁻⁵? Then, if the point is right, you'll take it to the site. So do plus or minus one on whatever has 10-2 digits What will you do to him, minus one, if it's the same? I understand point shifting now; I'm moving forward. With the numerics I have shared with you, which I have placed a great deal of trust in Shall I do it for you, or shall I do it very well for you? If you clearly understand these two things, how will you convert from picometer to meter? How do you do centimeter measurements, and the second point, how does shifting work? So you just sort these numerics, one two, and whichever one you have It seems like you're asking about a situation where, if you get a 10% discount, what should you do? Tell me, what would you do for the Tetheshat Choo Maanlas Ett key Qub? Tell me, will you multiply eight by eight if eight times two? 16 8 3 go twenty or pier te ka na kitna ho ta hai tab ko mil jaye We won't be able to do it, so let's just go ahead and leave it at that. You do it, let's do it together with our Nimer Kika, Nimerkalas is still waiting. First, if you're solving numerical problems, never skip writing down the given data. If you don't write down the given information, you won't know what to do, what not to do, or what steps to follow. If you skip writing down the given data, you'll miss out on a lot. That's why it's essential to work with the given data in numerical problems. When it's numerical, and you're given a formula for it initially, what is the formula? Given the image, I'll tell you: look at the formula you heard just now. What is your formula? Is it Kefa Row? Costoo? And on each pass, you will be required to pass, but you will be empowered to bypass it, provided that when you are given the peak meter, you will first convert it into the centimeter meter. First, let's talk about Aijj Lengd. We don't take it from here. Don't take it too seriously, it's just a joke. 408 Pico meter, exactly exactly Will this go in meters now? No, what should I convert the meter into? In centimeters, if it's correct, what will you do to measure in centimeters? Multiply by hand Then it will be 408. 10 rest minus 12 Now listen with meditation Minus 12 is, plus 2 So what will this become? 408 into 10 rest you How much will it come to if you do this? -10 Will the children come today? -10 Now remember one thing You have to cube it. If you need to make large cubes Always hit him in the digital area What are you trying to do? How are we going to bring this into digital form? What should we do? There's a point here. 408 points Here is the point Mother, you eat so much jaggery. I'm Wave Madsh Connie No, no, your humble servant is not that kind of person. They go along with us, those who accompany us. We are the ones who are being deceived by this illusion. Whose value are we moving forward, kids? This one value, let's move forward. Now, what do we do with the value? We put it. Just like that, nothing but what is its molar mass? Tell me, 197, 197 grams per mole. After that, one IP, one IP, look here, it has come up here. What will happen to centimeter? Look after that, what happens with these, these numbers? Avagadro's number, so that's six point zero two two times ten raised to twenty-three grams per mole. What is grams per mole? Correct, children, here it is, these What will happen here exactly, and do you know the values of mol and n? Here, the value of n is 4, and what is the value of n? Let's do the calculation step by step. I'll first loosen it up a bit; it'll be a little tricky. Now watch closely. Focus here: 1.97 grams per mole divided by 4, divided by water. That's cubing it. Yes, you can easily cube this. It was originally 408, which was difficult to cube, so I said shift the decimal point; it will be easier now. Look, this is just a single digit, and in four points, it's just a single digit as well. What is the square root of 64 divided by 8? If you calculate it, you'll get 1. So, it's exactly 1. Perfectly clear, nicely done. It will be light, and the answer is 10 C. You got it right, well done. Calculate it and tell me what you'll write as the answer. Okay, now look, you can simplify this even further. For example, 197 grams times 64.2 divided by ten remainder. Look, this ten remainder is 24, and this ten remainder is 23, so it will be minus ten. Ten minus 1 into 6.0. Okay, now you will divide this. This can now be divided. Its value, I can multiply by I later, then you can divide it. So when you are dividing this, I will divide it. Okay, minus one times six point zero. Ya 19.27 cm³ Rar simply 1000 per kg To convert You have to multiply it by 1000. So 19.27 × 10³ kg per cubic meter What will happen to kg per cubic meter? What have you not done in converting grams to kilograms? Multiplied by 1000 What have you done, kids? Multiplied by 1000 Calculate this for me You will receive 19.27 Since Calculus is still correct, you can multiply by 6.4, divide by it, and you can talk about your own matter.

This is Ballu, this one is the other one Ala Opsengar Which atom is ours, D atom? What is this atom of ours, D atom? Which atom is ours, D atom? The formula asked from you is what will be the formula of c and d? I'm awake, I know how to do it. Look at you, what did I say first? What did I say first? Listen to what I said about Atma. The pressure applied by the piston in the cylinder compresses the air, which then pushes the piston upward. And how much does he earn? One by eight, meaning, listen carefully. I've read this chapter, so I'll tell you about it in great detail. Because one that is an atom, not a corner one He shares it with eight people. At the Oatmeal, eight people share it Put a corner here, put a corner up here Shotaro is an atom, and he was talking about it. So it will become 8 times 8, which is 64, and what will you get?

First, sir, let's have lunch 144.4 × 10⁻¹² m Now tell me, children, what should we convert meters into? in centimeters So 144.4 × 10⁻¹² × 10⁻² Multiply by 100, should be 10-2, write it down What will happen to you, centimeter? Now listen to the rice Minus twelve plus two, so what will it become? 144.4 × 10⁻¹⁰ What have I said, such a big number to you The problem will arise later; I'll show you where right now. The problem will arise; I'll convert it first. The problem will arise, so I need to listen to the recording first. There will be a problem. You are aware The problem will arise For clothes, the packing efficiency was so high that it seemed like you could fit a whole route into just four.

Maybe you only need to calculate the cube of 1.44. Is it okay? -8 What do we do with the sum of it? We have to perform vertical summation. What do you have to do this over R cube? The value of R is here Now I have to do R cube Now carefully observe how to cube it 4 × 3 × 3.14 × 1.14 And you have to multiply it three times. But the bug will come this much, it will come this much, up to three. Keep cubing 1.4, Tikkie, keep going This is the deadline for linked licensing; otherwise, this toko deadline will be missed. You can also sleep in Marge London, so I'll take the sofa. to 23 24 And Prash Prash, these are for you What was this supposed to be done in? I didn't write the unit at all. 10 tons 8 cm now is cube, so its If you cube it, where will this come to you? It will come in cm cube, right? Its You'll have to cube it, right? Will this also be in cm? Go to the cube and move on. So, your volume is set now. Here it is. Unit seal okay Here it comes Come on, now let's move forward to the next one. What exactly do we need to extract? So how did you used to calculate? Whatever volume you have set now, the unit would be sealed. There was a volume, exactly right. What did you do to him? Number of particles We used to multiply by it; look, I'll tell you what you need to calculate. The previous volume occupied by particles in the unit cell How will you extract it? Whatever volume you were getting that is 1.261 10 to the power of 24 cm cube Whatever has come to you What will you do to it? Number of particles Multiply it by How many particles will there be? Four, you need to multiply this. and you will get what 5.044 10 to the power of 23 10 to the minus 20 3 cm cube OK Listen to the divine What we needed to find now was the third one's percentage. Volume occupied by the Ag to Volume occupied by particle in the unit cell upon total volume So, what will remain in your derivation? How to calculate the volume occupied by the particles in the unit cell Whatever volume you were getting Then you will fall down and get beaten So this is it This is this. So this This Afya Milya has been instructed to keep the life in the Ab Paroolé. This formula is our formula; we will maintain it. From now on, we will be safe. 504 ing tattan tarsev mākra voliyūm.

So it will go up there It will go, it will go Will go And where will the cows go? 3.25 × 10⁻²¹ What has happened to you? number of atoms present in x grams The second one you need to find out is in what. The second sir we need to find out number of unit cells What exactly needs to be found out in the second one? number of unit cells in x grams Right on What is its formula? x upon row aq n will no longer be in this. You will know the value of x. Tell me the value of x Okay The value of x is 0.5. gram What is the value of row? 8.55 grams per cm³ And do you know the value of aq? that is 3.306 × 10⁻⁸ What will happen to cm³? cube Alright, kids Do you all understand what needs to be done? Now, please multiply this properly. As I mentioned above Right on, and you'll get one point You will receive some value across If I do this, then I will get 1.62 x 10⁻²¹ Okay This is very easy. If you are referring to the unit cell and asks for the number of particles or atoms Listen carefully If you have number of atoms how many atoms Or does it ask about the unit cell? So, the formula for the number of atoms is and number of The formula for the unit cell is Both formulas are the same, just one has n. It asks for the value of both, not n in one. And you will get the answer, correct? Do it this way The way to simplify it, but you should have known it Do it just as I'm telling you, and it will be very easy. Alright, let's move forward now toward our next problem. Problem 1.4 So it turned out crooked. the compound is formed by two elements a and b the number of atoms B forms CCP structures and the atoms occupy one third part of the tetrahedral white and what is the formula of the compound Compound A is formed two elements A compound is formed by two elements. a and b the atoms b-form CCP structures What form are you filling out? CCP structures. Okay, let's go. Now, what should we do, kids? Here. the atoms of elements B form CCP structures, well, the one belonging to my B-type What are they forming, CCP structures? Now that they form CCP structures Doing it, then CCP Something to form structures When atoms are present, attention will be given to all of them, and one atom will be taken from the pile. Indra is not there, so the atom will be taken by someone else. This is just a little sweaty sensation, how much envisioned something, a little living, something mindful, what is it. Shore choo, johoe choo, johoe choo, euiałat world apparatus assimilated or And what are the Valleys of the Octa Hedral Boyt? Or is this just a place to come here? Let's go. Now, what is the next costume you have? There was a sudden flash, and I saw a figure emerging from the darkness of the crater. So, how much is Titra Hotel White? 2N 2N? Okay. Now we need to A has been obtained, B has been obtained. So now we calculate the ratio. Whatever they ask us, the compounder Formula A and B. Okay? What is 1 by 3? You can solve it if you want to. What should I do with this now? Just multiply here. Because it should not happen in fractions So this is now What will happen? 2, 3 Meaning A2, B3. What will the answer be? What is the compound of the formula? A2, B3. What will be obtained? Let's talk about the Star at the bottom of the page. You must be feeling exhausted. But it's very easy, just try to understand Actually, atom B is also a very important point. What is this B atom? He's talking nonsense. Atom, who do you hate from this? Who are you going to blame for this? Kerfhir Sharchagi We are playing the game of hide and seek. So, you'll receive the bill, a single value, so we've obtained the ratio of A to B, which is exactly 2n over 3. And B's value is n, calculate it, double it, and bring it over there—then you'll go there. This three A squared B three, this will be your answer, three A squared B three, this is your answer today, A squared B three. There are people in Ashel Port Prinj who say that I am not an inferior one for Prinj Prinj's Prinj, nor are we. If you're feeling tired, then India is playing, so let's go ahead and play on the board. What is the formula for Aggrote Headcount Equal to Number of Are we given the number of atoms, or not? Given moles, what has been given? So, what should we do? Convert moles into atoms: number of moles = 0.4 moles 0.4 × 6.022 × 10²³ The water pipe is not working properly; the water flow is weak. 6.022 × 10²³ atoms are contained in one mole. Oktah Headl Votr Can Be Told Multiply this and whatever answer you get, what should you do at that place? Multiply this and whatever answer you get will be placed there. So, just go behind all the tanks, go behind, you'll really like it. That tank, that tank, this weight, this guy, get this video and please, trash can, this tank, go to the tank.
