Through elimination, starting with the most obvious properties of each compound, we can steadily derive the final answer to be B which is Copper(II) Carbonate. 1) CuCO3 --> Insoluble in Water 2) CuCO3 upon heating --> CuO + CO2 3) CuCO3 + Acid --> Salt + H2O + CO2 Hope this helps.

Through elimination, starting with the most obvious properties of each compound,
we can steadily derive the final answer to be B which is Copper(II) Carbonate.

1) CuCO3 –> Insoluble in Water

2) CuCO3 upon heating –> CuO + CO2

3) CuCO3 + Acid –> Salt + H2O + CO2

Hope this helps.
