A solution is saturated in both nitrogen gas (N2) and potassium chloride (KCl) at 75°C. What happens when the solution is cooled to room temperature?

Some of KCl will precipitate out of the solution.

Explanation:

Gases solubility increases with decrease in temperature and therefore nitrogen gas will not bubble out is the temperature is dropped from 75 deg C to room temperature.

On the other hand, KCL is a salt in solid state and the solubility of solids decreases with decrease in temperature. Therefore some of the KCl will precipitate out of the solution when temperature drops from 75 deg C to room temperature.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
