why HNO3 does not react with metal to form salt and hydrogen gas

As the HNO3 also known as nitric acid.And Nitric acid is a string oxidizing agent. So as soon as hydrogen gas is formed in the reaction between a metal and nitric acid, the nitric acid oxidizes hydrogen gas to water and itself get reduced to any of nitrogen oxides. Thus nitric acid does not release hydrogen gas upon reaction with metals.
The reaction between Mg and HNO3 is given by-
4Mg+10HNO3→4Mg (NO3)2+NH4NO3+3H2O

Answer:
Nitric acid(HNO3) is a strong oxidising agent. The Hydrogen gas produced during its reaction with metal gets oxidised to H2O, hence no hydrogen gas is produced. Instead it evolves nitric oxides such as NO2,NO etc
