Thermal Decomposition of Carbonates

Hi,

I have a practical assessment tomorrow which deals with the Thermal Decomposition of a metal Carbonate.

Is it possible to write Ionic Equations for the reaction? Ionic solids and solutions are involved, but the reactions seem to be Double Decomposition, especially the test for CO2

Also, how is it possible to predict the state(solid, liquid,gas) of a chemical?

CuCO3 + CuO --> CuO + CO2

CO2 + Ca(OH)2 --> CaCO3 +H2O

CuO + H2SO4 --> CuSO4 + H2O

Some of these reactions take place in solution, so some reagents will be in the form of ions.

Your first reaction has an unnecessary CuO on the reactants side.
