Answer:
Nitric acid HNO3 is 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.

Explanation:
Hydrogen gas is not evolved when a metal reacts with nitric acid. It is because HNO3 is a strong oxidising agent. It oxidises the H2 produced to water and itself gets reduced to any of the nitrogen oxides (N2O, NO, NO2).
