Explanation:
Nitric acid HNO3is a strong oxidising agent. The Hydrogen gas produced during the reaction with metal gets oxidized to H2O
, hence no hydrogen gas is produced. Instead, it evolves nitric oxides such as NO2,No etc

Zinc metal gives hydrogen gas when it is treated with dilute sulphuric acid. Hydrogen gas is utilized in hydrogenation of oil.
Zn+2HCl→ZnCl

+H

Therefore, the gas evolved is hydrogen.
Test for hydrogen gas: When a burning candle is brought near the hydrogen gas, it burns with pop sound which confirms the presence of hydrogen gas.
