Solution

Dear student

On Heating

1 Ferrous sulfate decomposes to ferric oxide and SO₂ and SO₃ is released
2FeSO₄ = Fe₂O₃ + SO₂ + SO₃
2 Lead nitrate decomposes to lead mono oxide and liberating NO_{2 and}O₂
2 Pb(NO₃)₂ = 2PbO + 4 NO₂ + O₂
3 Calcium carbonate is broken down into CaO and CO₂ is liberated.
2CaCO₃ = 2CaO + 2CO₂
4 Copper sulfate crystal loses its water and becomes colorless.
CuSO₄ .5H₂O = CuSO₄ + 5H₂O
