2 g of green coloured crystals of ferrous sulphate are heated in a dry boiling tube. Name the type of chemical reaction taking place. Write the balanced chemical equation for the reaction. Is this an exothermic or an endothermic reaction ?
Solution
• Thermal decomposition reaction
heat
• 2FeSO4 (s) → Fe2 O3 (s) + SO2 (g) + SO3 (g)
(deduct ½ mark if no / incorrect balancing)
• Endothermic reaction
