Which equation is correct? Aim: Copper has two oxides, Cu2O and CuO. 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) + 1/2 O2 (g) Equation 2: CuCO3 (s) CuO(s) + CO2 (g) I must determine which equation is correct. Introduction: From the two equations we can see when copper carbonate is heated or decomposed gases are given off. To find which equation is correct we can use ideas about moles, plan and design an experiment to measure a volume of gas that will prove which of the two equations is correct. Therefore to find out the correct equation I will need to decompose the copper carbonate by heating and after this I will measure the amount of gas produced. The volume of gas will help me determine which equation is correct. * It is possible to determine...
