Answer 2

Explanation:

↬Decomposition of nitrates, nitrites and ammonium compounds

Barium azide on heating yields barium metal and nitrogen gas. Sodium azide on heating at 300 °C gives nitrogen and sodium.

↬Calcium carbonate

Calcium carbonate decomposes, on heating , to form calcium oxide and carbon dioxide. When 10 g of calcium carbonate is decomposed completely, then 5.6g of calcium of oxide is formed.
