(except Mn and Mg)? *
O H2504

O All of these​

Answer 1

Answer:

Explanation:

Hydrogen gas is not evolved when a metal reacts with dilute nitric acid because nitric acid is a strong oxidizing agent. So, as soon as hydrogen gas is formed in the reaction between a metal and dilute nitric acid, the nitric acid oxidizes this hydrogen to water.
