Answer 1

Answer:

I think you want ot know what happens when feso4 crystals, which are green in colour, are heated.

Here is the reaction that takes place:

FeSO4(s) → Fe2O3(s) + SO2(g) + SO3(g)

Explanation:

When ferrous sulphate crystals are heated, ferrous oxide(brown in colour) which is commonly called rust is formed.

In addition sulphur dioxide and sulphur trioxide are liberated as gasses which have a smell of burning sulphur.
