The Thermal Decomposition of Copper Carbonate Copper carbonate goes through thermal decomposition to form one of these oxides. The two possible equations are: Equation 1: 2CuCO(s) CuO (s) + 2 CO (g) + 1/2 O (g) Equation 2: CuCO (s) CuO (s) + CO (g) Aim To find out which of the above equations is correct. I will use the mole theory to work out the expected volume of gas released. This predicted will volume will prove which of the two equations is correct. Apparatus 100 cm³ gas syringe 2 retort stands Clamp Delivery tube through bung Test Tube Bungs Bunsen Burner Heat Proof Mat Top pan Balance Spatula Chemicals Powered Copper Carbonate Amounts and Errors I will collect the amount of gas produced in a gas syringe, and aim to collect approximately 80cm³ . This volume is far enough from the 100cm³ to account for any errors that may cause the volume to increase beyond the scale, if too much gas is evolved. The gas syringes...
