Hi, can anybody help me answer these exam questions

Equation given is :

CuCo3 (s) + H2SO4 (aq) > CuSO4 (aq) + CO2 (g) + H2O (l)

Copper Sulfate crystalizes as its hydrated salt CuSO4.5H20

1) Describe what you would observe as Copper (II) Carbonate is added to sulfuric acid, followed by heating

2) Explain why, Copper (II) Carbonate is added until 'some solid remains after heating'

3) Suggest what would happen if heating was continued untill all the water had evaporated away

4) Describe the appearance of a sample of copper (II) Sulfate

5) The copper (II) Carbonate may of contained some Copper (II) Hydroxide
Explain why this does not affect the maximum mass calculated and does lead to the foramtion of any Copper (II) compound apart
