Question

Identify the type of chemical reaction and write balanced chemical equation for the following (1) Barium Chloride solution is mixed with copper sulphate solution and a white precipitate is formed (2)On heating green coloured ferrous sulphate crystal reddish brown solid is left and smell of burning sulphate is experienced

Answer 1

(1) It's a double decomposition or precipitation reaction.
Chemical Equation :
BaCl2(aq) + CuSO4(aq) = BaSO4(ppt) + CuCl2(aq)
(2)It's a decomposition reaction.
2FeSO4 =Fe2O3+SO2+SO3
