That salt was iron sulphate. Iron sulphate(FeSO₄) produces a colourless suffocating gas and leaves behind a brown residue.
FeSO₄ (s) ⇒ Fe₂O₃ (s) + SO₂ (g) + SO₃(g)
(green) (brown)

Answer: 1. The salt is ferrous sulphate
2.
Explanation:
Decomposition reaction is a reaction in which one reactant forms two or more than two products on absorption of energy.
Ferrous sulphate which is green in color undergoes decomposition, that is it breaks into two or more than two products on absorption of energy. Two gases are evolved namely sulphur dioxide and sulphur trioxide and a solid ferric oxide which is brown in colour remains as such and is called as residue.
The balanced chemical equation representing the decomposition is:
