Aim- To determines the correct equation of the thermal decomposition of copper carbonate. The two possible equations are shown below: Equation 1: 2CuCO³ (s) --> Cu²O (s) + 2CO² (g) + 1/2O² (g) Equation 2: CuCO³ (s) --> CuO (s) + CO² (g) Apparatus * Heat mat * Clamp stand * 100ml gas syringe * Conical flask * Bunsen burner * Tripod * Tube/hose with bung attachment * Top-pan balance * Gauze Chemicals Powdered copper carbonate Calculations I expected the volume of gas would be 80cm³. This is because the bigger the volume of gas, the smaller the percentage error for the gas syringe as it is 100ml which has small graduations and big scale. V/24000 = n 80/24000=3.33 x10-³ m/Mr = n Mr x n =m Mr=molar mass n=mole m= mass R.M.M of copper carbonate = 63.5 + 12 + (16 x 3) = 123.5 grams 123.5 x 3.33 x10-³ =0.4g So in this experiment, I decide to use 0.4g of copper carbonate. Equation 1: Using 0.4...
