Planning Introduction I'm going to produce a piece of coursework, which determine the Decomposition of Copper Carbonate The purpose of decomposing CuCO3 is to determine the volume of CO2 gas that evolves. In this experiment, the water displacement method is used to recover the gas evolved. The volume of CO2 collected is converted to dry conditions, which is then compared to the theoretical volume calculated. As copper has two oxides Cu2O and CuO, when copper carbonate (CuCO3) decomposes on heating to form one of these oxides and an equation can be written for each possible reaction: Equation 1: 2CuCO3(s) ------> Cu2O(s) + 2CO2 (g) + 1/2O2 Equation 2: CuCO3(s) --------->CuO(s) + CO2 (g) My aim is to find out which of these equations is correct. Hypothesis I predict that the CuO compound will be formed, because this is in line with the pilot results, and would be supported by the background theory. Copper most commonly...
