Name a compound which on thermal decomposition gives N2.Write

equation for the reaction​...

Answer:

Nitrogen gas is obtained by thermal decomposition of ammonium nitrite, ammonia and ammonium dichromate.

Ammonium dichromate on heating yields nitrogen, water and chromium(III) oxide and ammonium nitrate on heating yields nitrogen gas and water.

CaCO3 → CaO + CO. The reaction is used to make quick lime, which is an industrially important product. Some oxides, especially of weakly electropositive metals decompose when heated to high enough temperature. A classical example is the decomposition of mercuric oxide to give oxygen and mercury metal.
