Solution

A chemical equation is the symbolic representation of a chemical reaction. With the help of symbols of elements and formulas of compounds, a chemical reaction is explained as a simple equation for better understanding.

One of the essential conditions of writing a chemical equation is that the total number of atoms of all the elements on both sides (LHS and RHS) of the chemical equation should be equal.

Example:

2H₂ + O₂ $\to$ 2H₂O
Reactants Product
