Calcium carbonate (CaCO3) is a white solid with no odor. When CaCO3 is heated, the resulting substances are calcium oxide (CaO) and carbon dioxide (CO2). CaO is a white to gray solid with no odor, and CO2 is a gas with no odor and color.


Which statement describes CaCO3?


A) It is a diatomic molecule that can’t be broken down by physical means.

B) It is a diatomic molecule that can’t be broken down by chemical means.

C) It is a compound that can be broken down by physical means.

D) It is a compound that can be broken down by chemical means.

Calcium carbonate is a compound that can be broken down by chemical means.

The given compounds;

reactant = CaCO₃

product = CaO + CO₂

In a chemical reaction called thermal decomposition, lime stone also known as calcium carbonate can be broken down when heat is applied to it. It is a chemical process because new substances such as quick lime (calcium oxide) and carbon iv oxide will be formed.

The overall reaction is given as;

CaCO₃  → CaO + CO₂

Thus, we can conclude that calcium carbonate is a compound that can be broken down by chemical means.
