Answer:
solvent (such as water, oil or isopropyl alcohol) is allowed to absorb up the paper strip. ... Different molecules run up the paper at different rates. As a result, components of the solution separate and, in this case, become visible as strips of color on the chromatography paper.

Answer:
Use the activity formula,
T1/2 = 4.468 x 10^9 yr x 365 x 24 x 3600 = 1.409 x 10^17 sec
l = ln(2)/T1/2 = ln(2)/1.409 x 10^17 = 4.91932697 x 10^-18 s-1
DN/Dt = lN, 265 = 4.91932697 x 10^-18 x N
<u><em>N = 5.38 x 10^19 nuclei</em></u>

Answer:
The number of carbon atoms in the organic compound is 16.
Explanation:
The relative intensity of M + 1 peak (relative to M = 100) in organic compounds can be predicted by the following formula:
[M + 1] = (number of C x 1.07) ---------------------------------------------------- (1)
This formula can also be used to determine the number of carbon from the given intensity. But first, the intensity of [M + 1] relative to [M] = 100 needs to be determined, for which, consider the following calculations,
![[M+1]=(\frac{M+1}{M}) (100)](https://tex.z-dn.net/?f=%5BM%2B1%5D%3D%28%5Cfrac%7BM%2B1%7D%7BM%7D%29%20%28100%29)
![[M+1]=(\frac{7.022}{40.58}) (100)](https://tex.z-dn.net/?f=%5BM%2B1%5D%3D%28%5Cfrac%7B7.022%7D%7B40.58%7D%29%20%28100%29)
![[M+1]=17.30](https://tex.z-dn.net/?f=%5BM%2B1%5D%3D17.30)
Using equation 1 we get,
![number of C=\frac{[M+1]}{1.07}](https://tex.z-dn.net/?f=number%20of%20C%3D%5Cfrac%7B%5BM%2B1%5D%7D%7B1.07%7D)

or number of C = 16
The remaining value, 0.168, can be due to the isotopes of hydrogen and oxygen in the organic compound.
