Question

how CaCo3 undergoes thermal decomposition

Answer 1

Calcium carbonate on heating, decomposes to give calcium oxide and Carbon dioxide.

▶️ Calcium oxide is used for manufacturing of cement.

CaCO3 (s) --------------- CaO (g) + CO2 (g)

Answer 2

Calcium carbonate undergoes thermal decomposition CaCO3(s) ===> CaO(s) + CO2(g) at high temperatures.
