I think as brass has got zinc in it and it rapidly reacts with zinc and gets discolored.

Cu present in brass reacts with h2s & undergo corrosion i.e. Its get oxidised hence ultimately get discolourised.

Brass is a alloy so it can decolourise easily with hydrogen sulphide. .

Brass is a alloy of Cu and Zn so it can decolourise easily with hydrogen sulphide.

Brass is an alloy of Cu and Zn, when it comes in contact with H2S it forms zns and Cu2s which are black in colour hence brass gets discolured.

How we can learn to balace reactions for class 8th?

Why we choose hydrogen sulphide. You mean hydrogen can do any material to decolourize?
