उत्तर
The method of representing a chemical reaction with the help of symbols and formulae of the substances involved in it is known as chemical equation.
For example, zinc metal reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas.
This can be represented by chemical equation as follows:
Zn (s) + H2SO4 (aq) → ZnSO4 (aq) + H2 (g)
