Which Equation is Correct? Copper has two oxides. Cu2O and CuO. When Copper carbonate, CuCO3 decomposes with heat, two possible oxides are formed. Equation 1: 2CuCO3 (s) › Cu2O (s) + 2CO2 (g) + 1/2O2 (g) Equation 2: CuCO3 (s) › CuO(s) + CO2 (g) From the equations above I can see that in both reactions gas is released and by collecting the gas produced we can accurately say which reaction is taking place. To find which equation is correct I can use the ideas about the mole and the volume that one mole of gas occupies at standard conditions. In the test, it is very important to ensure a fair test and to do this certain things must be kept the same. Temperature, of the collected gas should be kept at room temperature, and care should be exercised when heating the sample of carbonate that the apparatus containing the gas evolved is not also heated. It may also be a good idea to let the gas released, to cool...
