Explain giving equation, what happens when:
(a) ZnC03 is heated in the absence of air?
(b) a mixture of Cu2O and Cu2S is heated?
Answer :
(a) When zinc carbonate heated in absence of air, it releases carbon di oxide gas and forms zinc oxide. We can see through equation as well.
ZnCO3→ ZnO + CO2
(b) 2Cu2O + Cu2S → 6Cu + SO2
Hence we can say that when a mixture of Cu2O and Cu2S is heated, carbon and Sulphur di oxide gas released.
