(A) When ferrous sulphate heptahydrate $(FeSO_4 \cdot 7H_2O)$ is heated,it first loses water of crystallization to form anhydrous ferrous sulphate $(FeSO_4)$.Upon further heating,anhydrous ferrous sulphate decomposes to form ferric oxide $(Fe_2O_3)$,sulphur dioxide $(SO_2)$,and sulphur trioxide $(SO_3)$.The chemical reaction is as follows:$2FeSO_4(s) \xrightarrow{\Delta} Fe_2O_3(s) + SO_2(g) + SO_3(g)$
