Answer 2

Explanation:

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

The required reaction :-

CaCO 3 → CaO + CO 2 ↑

Property of above reaction :-

1) Endothermic

2) Slow reaction

3) Less heat released

4) Gas released converts lime water milky .

5) It is a thermal decomposition reaction .

Importance of above reaction:-

1) Used for obtaining pure calcium

2) To practically obtain carbon dioxide

3) To form Lime and further lime water .
