20 g of CH4 is burnt with 150 g of O2 producing 675 kJ of heat Assume that the amount of oxygen required is in accordance with the equation CH4 g 202 g CO g 2H O 1 After the reaction an excess of Cl2 is added to the reaction mixture and 77 g of CCl4 is obtained a The enthalpy of combustion of methane is 900 kJ mol 1 and the amount of O remaining unused is 16 g b The enthalpy of combustion of methane is 900 kJ mol 1 and the amount of O remaining unused is 48 g c The enthalpy of combustion of methane is 900 kJ mol 1 and amount of O remaining unused is 54 g d The enthalpy of combustion of methane is 920 kJ mol 1 and the amount of O remaining unused is 32 g
