\text { Whirc phosphorous on reacrion wirh Ca(OF l) gives } (a) $\mathrm{Ca}_{3}\left(\mathrm{PO}_{\mathrm{i}}\right)_{2}$ (b) $\mathrm{PH}_{\mathrm{z}}$ (c) $\mathrm{Ca}\left(\mathrm{ll}_{2} \mathrm{PO}_{2}\right)_{2}$ (d) $\mathrm{Ca}\left(\mathrm{H}_{2} \mathrm{PO}_{1}\right)_{2}$

In this problem, PS three will be the correct answer. Just look at it carefully. Be it for I. Plus any or Edge gives first fin what did and and sodium I'll died as the product. So just look at it carefully. Did he? X. N. Can be written it th for I Plus any Edge will react to give PS three plus as to plus any I. D. Product. So option seeds correct here. BSD is the answer. I hope you understand the solution of this problem.

K two Cr awful gives a yellow precipitated it's a yellow policy heated on reaction with on reaction with Be a two plus, as well as B B two plus, therefore, option C and option the uh, correct answer for this problem, Option C and option B. R. Correct answer for this problem.

Now in this part we are asked to find out the yellow respect. You'll notice right the sequence of the reactions of the year being N no three or two. This upon hating will produce. Yeah, mm. No, this is a fun reaction were diluted. Well you the the L two. No, we have video on reaction with alimony, um ammonium carbonate, ammonia carbonate. This will produce, he is C. 03 This is uh now this upon reaction will dilute at cl will produce S E L two B S C L two. Upon reaction with potassium promenade this will produce E A R Bs er of or no B S C R. O. For upon reaction with dilute sulfuric acid, it is a source of work. It will produce B. A. S. Awful. So this is Yeah, this is the better answer. E. S. 04 Yeah. So far is there direct And and this is this is the final product. But we're asked to find out the yellow pre speed. So this is the yellow principle. Hello, is it the B A c R 04? P a c R O Forest to Yellow Pre spirits. So let's check out the options. We see. Obscenity is going to Son. He is going to B S c R 04 is uh, yellow precipitate.

This video's gonna go through the answer to question number 11 from chapter 9.3. So ask to use real reduction to find the inverse off the matrix. That 11 one 121 Thio three. So So we conform the combination matrix with the identity and they tried refugees. Okay, so if we subtract to you off the top equation from the bomb equation, then we're gonna get zero one that to you, minus 20 Maybe it's gonna be minus 201 on the inside. And if we should bottle subtract one of the first question from the middle equation, that's gonna be zero That's gonna be one on that's going to zero months. Well, on zero on me, the top equation as it is, Savior zero. Okay, so now we get to be a stick in court because on left inside the bomb equation on the middle or after the bottom row of the majors in the middle of the matrix. All the same, which means that the ah, the row is off the matrix linearly dependence, which by their a born in the book, means that er the identity that's all right with me
