Solution

Balanced chemical equation: A balanced chemical equation represent the equation in which the number of atom of each element is equal on both the reactant and product side.
Given reaction: $\underset{Hydrogen sulphide}{H_{2} S} + \underset{Oxygen}{O_{2}} \overset{}{\to} \underset{Sulphur dioxide}{{SO}_{2}} + \underset{Water}{H_{2} O}$
Balancing of chemical reaction:
Step 1: Writing the number of atoms on each reactant and product side

Oxygen (O) is unbalanced in the above chemical reaction.
Step 2: Balancing the Oxygen atoms
Multiply the Oxygen by 3 on the reactant side; Sulphur dioxide and water by 2 on the product side.
$\underset{Hydrogen sulphide}{H_{2} S} + \underset{Oxygen}{3 O_{2}} \overset{}{\to} \underset{Sulphur dioxide}{2 {SO}_{2}} + 2 \underset{Water}{H_{2} O}$
Step 3: Balancing the other unbalanced atoms
Now, the Hydrogen and Sulphur atoms are unbalanced. So, balance them by multiplying hydrogen sulphide on the reactant side by 2.
$\underset{Hydrogen sulphide}{2 H_{2} S} + \underset{Oxygen}{3 O_{2}} \overset{}{\to} \underset{Sulphur dioxide}{2 {SO}_{2}} + 2 \underset{Water}{H_{2} O}$

All the elements have an equal number of atoms.
Thus, the balanced chemical equation is $\underset{Hydrogen sulphide}{2 H_{2} S} + \underset{Oxygen}{3 O_{2}} \overset{}{\to} \underset{Sulphur dioxide}{2 {SO}_{2}} + 2 \underset{Water}{H_{2} O}$
