I COULD NOT UNDERSTAND THE CHEMICAL EQUATION-
2FeSO4 = Fe2O3 + SO2 +SO3
how is it formed and why once SO3 and then SO3.
pse define how do we make equation ie. on the basi of reactivity of elements or some other basis.
regards

Expert Answer
- Ferrous sulphate crystals contain water molecules as the water of crystallisation - (FeSO4. 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 the ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3). So, the gas emitted smells like burning sulphur.
