A ccrrain pale grocn subsrancc, (A) becomes dark brown on axkting $\mathrm{NaNO}_{2}$ in prcscncc of dil. $11, \mathrm{SO}_{4}$ irs aqucous solurion gives prccipitarcs wirh (1) $\mathrm{BaCl}_{2}$ and (II) $\mathrm{NaO}] 1$ The larrer NaO1 I in scparare resrs. The larter prccipitare (B), gradually changcs colour from grcen ro brown, on cxposure to air. Whar is A?

In this problem, I'm writing the reaction so just look at it carefully. S 04 two minus plus B A two plus. We will react to form B and so forth. This is white PPT and the second reaction happened. Something like this. S artery two minus plus, Be a two plus will react to form B. A. Absolutely. And this is also white PPT. Therefore, according to the option option C. H. Correct answer for this problem.
The given function is Then -6 students in discussion. We have to find the value of the given techno magic function by using even all matters as we know that if I have to do is a function, then the function which, after all, is said to be even give the value of minus theta is equal to the original function. That means that means after to And also we know that 20,000 or concerned because then minus theta equals to understand to to So use this formula to solve a given function. So giving function can be Dennis then minus 60 degree. He was 2 -10, 16 and we know that the value of 1060° is square root of today. So the value of the guarantee automatic function is -3.
Okay, So this question wants us to find the decryption for this cryptogram given the coded romain tresses in the Matrix we started with. So the first thing we gotta d'oh just find the inverse matrix for decoding. So since this is a really computation heavy problem, you should use your calculator for this or Wolfram Alva, and you can see the a inverse is given by negative five, 23 negative one. And we're gonna need this a lot. So no, we decrypt the rose. So, for example, we d'oh the first row maitresse e a times a inverse. And this gives us our first decrypted phrase which is multiplying everything out eight and one. And then we just do this process for every room. So it's row times a inverse equals decoded a row. And we do this for every single row maitresse e And what we end up with is our decryption. So we get ate a 81 than 16 16 then 25 zero. Then we get 14. Five and again you should use You definitely should use Wolfram Alfa for this. Where? Your calculator? Because this is not fun to do by hand or even feasible to do by hands that our next is 23 zero. Then we have 25 five one, 18. So this is our decrypted thing. And now we just gotta replace every number with a letter remembering that zero was a space. And this too Crips, too happy Space knew space year. And we get that just by replacing each number by its corresponding letter.
We're going to do problem number 37. Discussion. We have to find the Valley off 10. 87.32 degrees. Okay, We have to find the value by using a calculator, and we have to round off the answer till four places off decimal. So what we're going to do, we're going to press 10 key on the calculator. Okay. After that, we'll place the value that 87.32 and then we will, um, but just press the degree key after that. Very close. Okay, So the value which we will receive for this is 21 13634 So the answer for the cistern, the 1.363 ft, that's all. Thank you.
