Emma Miller Chemistry Coursework Copper has two oxides, Cu O and CuO Copper carbonate, CuCO decomposes on heating to form one of these oxides and an equation can be written for each possible reaction: Equation 1: 2CuCO (s) Cu O(s) + 2CO (g) + 1/2 O (g) Equation 2: CuCO (s) CuO (s) + CO (g) My aim for this experiment is to find out which equation is correct, I will use my knowledge of the relationship between the mole and the volume to prove which equation is correct. In order to do this I will have to measure the volume of gas evolved from the two experiments. To begin my experiment I need to know how much (the mass) of copper carbonate I am going to use for each equation so that enough gas evolves to be easily calculated and so that my test is fair. To work out the mass firstly we need to find...
