We have been given an equation.$\mathrm{Zn}\left(s\right)+{\mathrm{HNO}}_3\left(aq\right)âŸ\P {\mathrm{H}}_2\left(g\right)+\mathrm{Zn}{\left({\mathrm{NO}}_3\right)}_2\left(aq\right)$

The steps below are used to balance the equation.

• Calculate the number of distinct types of atoms in the reactants and products.
• Increase the amount of atoms or molecules in the substances by putting coefficients in front of symbols or formulas as needed.
• Repeat steps one and two until the equation is balanced.

By repeating these steps, we get
