Question

Solid solid calcium carbonate is heated and decomposes to solid calcium oxide and carbon dioxide gas

Answer 1

Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide.

CaCO3 on heated it becomes CaO and CO2

Answer 2

When Calcium Carbonate is heated Calcium Carbonate decomposes into Calcium Oxide and Carbon Dioxide.

1. $CaCO_3$ → $Cao + CO_2$
