Normally metals react with dilute acid to form a salt and evolve hydrogen gas but I have read that hydrogen gas is not evolved when a metal reacts with nitric acid (because Nitric acid is a strong oxidizing agent). It instead oxidizes the hydrogen evolved to water and itself gets reduced to any of the nitrogen oxides ($\ce{N2O}$ or $\ce{NO}$ or $\ce{NO2}$). Then how to write the equation for the reaction of calcium with dilute nitric acid.
