Question 5.2
Translate the following statement into chemical equation and then balance it:

Hydrogen sulphide gas burns in air to give water and sulphur dioxide.

Answer 1

The chemical equation for the given chemical reaction is:
${\text{H}}_2\text{S (g)}+{\text{O}}_2\text{(g)}\to {\text{H}}_2\text{O (l)}+{\text{SO}}_2\text{(g)}$

The balanced chemical equation is:
$2{\text{H}}_2\text{S (g)}+3{\text{O}}_2\text{(g)}\to 2{\text{H}}_2\text{O (l)}+2{\text{SO}}_2\text{(g)}$
