The Decomposition of Copper Carbonate - Planning Coursework Aim Our project is to find out what products are formed when copper carbonate decomposes. Copper has 2 oxides, Cu2O and CuO. We are told that one of the following two equations are correct: Equation 1 (Eqn1): 2 CuCO3 (s) --> Cu2O (s) + 2 CO2 (g) + 1/2 O2 (g) Equation 2 (Eqn2): CuCO3 (s) --> CuO (s) + CO2 (g) Calculations I have to find out which of the two are correct by experimentation. By looking at the equations, I can see that gas is given out. Collecting this gas will be a good way to find out which equation is correct. I will collect the gas in a 100cm3 gas syringe. Therefore I want to be collecting about 80cm3 of gas per amount of copper carbonate. Eqn1 Ratio copper carbonate : gas 2 : 2 + 1/2 1 : 1.25 Eqn2 Ratio copper carbonate : gas 1 : 1 Above states that 2 1/2 moles of gas are produced in Eqn1. I...
