Question

what is the chemical formula for Iron sulphate gives rise to Iron (iii) oxide + sulphur dioxide + sulphur trioxide​

Answer 1

Explanation:

7H2O). On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white. On further heating, anhydrous ferrous sulphate decomposes to form ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3).

Answer 2

Explanation:

2FeSO4---->Fe2O3+SO2+SO3
