Introduction Aim Copper has two oxides, namely, CuO and Cu2O. 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 (g) Equation 2: CuCO3 (s) CuO (s) + CO2 (g) Our aim for the investigation is to find out which of the two equations above is correct and which oxide is formed when copper carbonate decomposes. Using the mole theory, an experiment is to be designed to measure the volume of gas, which will hence prove that which is the correct equation for the practical. The students also have to determine the quantities of reagents to be used in the experiment. Background Information Copper is a transition metal. It is found abundantly at many locations as a primary mineral in basaltic lavas and also as reduced from copper compounds. Copper pure is very malleable...
