Answer:

Because no two elements have the same set of energy levels, different elements emit different colors of light. Energy is released when electrons move from higher energy levels to lower ones (visible light).

Answer: The molar solubility of carbon dioxide gas is 0.17 M

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C_{CO_2}=K_H\times p_{liquid}$

where,

$K_H$ = Henry's constant = $3.7\times 10^{-2}mol/L.atm$

$p_{CO_2}$ = partial pressure of carbonated drink = 4.5 atm

Putting values in above equation, we get:

$C_{CO_2}=3.7\times 10^{-2}mol/L.atm\times 4.5atm\\\\C_{CO_2}=0.17mol/L=0.17M$

Hence, the molar solubility of carbon dioxide gas is 0.17 M
