Question #ed5e2
2 Answers
A sublimination
Explanation:
Sublimination is the phase change is the movement from a solid directly to a gas.
When acid rain hit limestone the limestone undergoes a chemical reaction releasing carbon dioxide gas. So part of the solid goes directly to a gas.
However technically this is a chemical reaction not a physical phase change. Sublimination is the best of the answers provided but it is not really a correct answer.
An better example would be heating solid iodine which goes directly from the solid to the liquid phase.
The answer is: None of the above.
Explanation:
One of the acids in acid rain is nitric acid.
It reacts with limestone according to the chemical equation:
Sublimation, condensation, and evaporation are all physical changes.
The reaction with acid rain is a chemical change.
Thus, none of the options is correct.
