Question

Calcium carbonate on heating decomposes into calcium oxide and carbon dioxide. Write the equation for the same and prove that law of conservation of mass is fulfilled.​

Answer 1

When CaCO3 is heated, it releases carbon dioxide CO2 known as thermal decomposition or also calcination. The reaction equation is: CaCO3(s)→CaO(s)+CO2(g) .

Balanced equation :-

As per law of conservation of mass,

Caco3 -> Cao + Co2
