The best choice that explains why atoms of carbon-14 (c-14) are unstable is there are 2 more protons than neutrons in the nucleus
<h3>
What is a stable atom?</h3>
An atom is said to be stable if the number of neutrons in the nucleus is greater than number of protons in the nucleus, because the the neutrons increases the nuclear force which keeps the atom stable.
Thus, the best choice that explains why atoms of carbon-14 (c-14) are unstable is there are 2 more protons than neutrons in the nucleus.

Answer : The concentration of water vapor in a sample of air is,
Explanation : Given,
Partial pressure of water = 0.91 torr
The total pressure of air = 735 torr
Parts per million (ppm) : It is defined as the mass of a solute present in one million parts by the mass of the solution.
Now we have to calculate the concentration of water vapor in a sample of air.
Now put all the given values in this formula, we get concentration of water vapor in a sample of air.
Therefore, the concentration of water vapor in a sample of air is,
