Identify the type of chemical reaction taking place in the following and write in balanced equation from a) Barium Chloride mixed with copper sulphate solution and a white precipitate is observed b) On heating green colour sirf ferrous sulphate crystals reddish brown solid left and smell of gas having order of burning sulphur is produced.

a. The balanced chemical equation is written below and this is a type of double displacement reaction.

Explanation:

When barium chloride reacts with copper sulfate, a white precipitate of barium sulfate is observed.

The chemical equation for the reaction of barium chloride and copper sulfate follows:

b.

2FeSO4--(heat)---> Fe2O3 + SO2+ SO3

This Reaction is an example of Thermal Decomposition Reaction.

the answer is 303.15 or 303
