Expert Answer:

Metal reacts with dilute acids to form metal salt and hydrogen gas.


Metal Reaction with acid Equation  
Sodium (Na) Sodium reacts violently with dil HCl 2Na+2HCl2NaCl+H2  
Magnesium (Mg) Magnesium reacts rapidly with dil HCl
Zinc (Zn) Zinc reacts less rapid than Mg
Iron (Fe) Iron reacts slowly with dil HCl



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). But magnesium (Mg) and manganese (Mn) react with very dilute HNO3 to evolve H2 gas.
