Question

Name a brown gas released during decomposition of Zn (NO3)2

Answer 1

This white, crystalline solid is highly deliquescent and is typically encountered as a hexahydrate Zn(NO3)2. 6H2O. It is soluble inboth water and alcohol. On heating, it undergoes thermaldecomposition to form zinc oxide, nitrogen dioxide and oxygen

Answer 2

The brown gas released in the decomposition of Zn(NO₃)₂ is NO₂ or nitrogen dioxide.

Zn(NO₃)₂→ ZnO + NO₂
