What happen when a) strongly heating of FeSO4 CaCO3 and lead nitrate.

1.	What happen when a) strongly heating of FeSO4 CaCO3 and lead nitrate.
Answer» 1)Lead nitrateonheatingdecomposes toleadmonoxide, nitrogen dioxide and oxygen. NO2 is liberated, along with oxygen, as a reddish brown gas. The residue left isleadmonoxide. ... Whenheated,lead(II)nitratecrystals decompose tolead(II) oxide, oxygen and nitrogen dioxide. 2)When ferrous sulphate crystals[FeSO4.7H2O] are heated, water of crystallization is lost. And then the anhydrous salt decomposes to formred brownferric oxide [Iron(III)] , sulphur dioxide (SO2) and sulphur trioxide (SO3) gases 3)Thermal decomposition occurs.Calcium Carbonatebreaks down into Calcium Oxide and Carbon Dioxide. ...CaCO3upon heating breaks down into CO2 gas and CaO. The CO2 gas can be checked by passing it through lime water , CO2 gas will turn it milky
