Answer:
Option B. Sodium
Explanation:
In the formation of NaCl, sodium loses and electron while chlorine receives the electron as illustrated below:
Na —> Na+ + e- ....... (1)
Cl + e- —> Cl- ......... (2)
Now, combining equation 1 and 2 we have:
Na + Cl + e- —> Na+ + Cl- + e-
Cancelling the electron from both side, we obtained:
Na + Cl —> Na+Cl-
From the above illustration, we see clearly that sodium loses electron
Answer:
It will take 3.3 s for [NOCl] to decrease to 0.042 M.
Explanation:
Integrated rate law for this second order reaction-
![\frac{1}{[NOCl]}=kt+\frac{1}{[NOCl]_{0}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5BNOCl%5D%7D%3Dkt%2B%5Cfrac%7B1%7D%7B%5BNOCl%5D_%7B0%7D%7D)
where, [NOCl] is concentration of NOCl after "t" time, ![[NOCl]_{0}](https://tex.z-dn.net/?f=%5BNOCl%5D_%7B0%7D)
is initial concentration of NOCl and k is rate constant.
Here, = 0.076 M, k = 3.2 
and [NOCl] = 0.042 M
So, ![\frac{1}{0.042M}=[3.2M^{-1}s^{-1}\times t]+\frac{1}{0.076M}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B0.042M%7D%3D%5B3.2M%5E%7B-1%7Ds%5E%7B-1%7D%5Ctimes%20t%5D%2B%5Cfrac%7B1%7D%7B0.076M%7D)
or, t = 3.3 s
So, it will take 3.3 s for [NOCl] to decrease to 0.042 M.
