Question

Question 49 (c)
An element X which is a yellow solid at room temperature shows catenation and allotropy. X forms two oxides which are also formed during the thermal decomposition of ferrous sulphate crystals and are the major air pollutants

Write the balanced chemical equation for the thermal decomposition of ferrous sulphate crystals.

Answer 1

Iron sulphate undegoes thermal decomposition to form iron oxide, sulphur dioxide and sulphur trioxide. The balanced chemical equation is given below:

$2{\text{FeSO}}_4\text{(s)}\stackrel{\text{Heat}}{\to }{\text{Fe}}_2{\text{O}}_3\text{(s)}+{\text{SO}}_2\text{(g)}+{\text{SO}}_3\text{(g)}$
