Hello!!

Your answer is:

The colour of ferrous sulphate heptahydrate crystals is light green. On heating, the water molecules evaporate to form anhydrous ferrous sulphate of white colour. On further heating, it undergoes thermal decomposition on heating to form red - brown ferrous oxide.

The equation for the reaction is in the above attachment.

Hope it helps you!!
