1.	2g of ferrous sulphate crystals are heated in a dry boiling tube
Answer» 2 g of ferrous sulphate crystals are heated in a boiling tube then we observe that :\xa0Ferrous sulphate crystals contains 2 water moelcules.On heating it looses water molecules and becomes anhydrous ferrous sulphate .Colour changes from light green to white .\xa0Ferrous sulphate crystals which are in green colour decomposes to give Ferric oxide , sulphur dioxide and sulphur trioxide gas.On further heating FeSO4 anhydrous changes to dark brown solid ..The gas emitted has the characteristics smell of sulphur.Chemical reaction :.2FeSO4 (S) -------------->Fe2O3 (S) +SO2(g) +SO3 (g)Anhydrous Ferric oxideFerrous sulphate
