Solution

A. CaCO3(s) + Heat→ CaO(s) + CO2(g)

CaCO3(s)

Calcium carbonate

CaO(s)

Calcium oxide

CO2(g)

Carbon dioxide

The balanced reaction of heating calcium carbonate.
B. In a decomposition reaction, the reactant breaks into two or more simple products. The heating of calcium carbonate results in the formation of calcium oxide and carbon dioxide. The reaction involved is given above.
Since it decomposes to give simpler products by absorbing heat so it is a thermal decomposition reaction.
