Solution

Iron react with Sulphur to form Iron sulphide

Part-1
Iron Sulphide react with HCl to release a rotten smell gas i.e H₂S

Reaction Involved-

FeS + HCl -----> FeCl₂ + H₂S

Part-II
Similarly,
Iron Sulphide react with H₂SO₄ to release a rotten smell gas i.e H₂S
FeS + H₂SO₄ -------> FeSO4 + H₂S
