What is a chemical equation? Explain with the help of an example.
✓

Answer

The method of representing a chemical reaction with the help of symbols and formulae of substances involved in it is called a chemical equation.
Example: Zinc metal reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas. This equation is written as, $\text{Zn}\ +\ \text{H}_2\text{SO}_4\xrightarrow{\ \ \ \ \ \ \ \ \ \ \ }\text{ZnSO}_4\ +\ \text{H}_2$
