Question
(ii) An industrial burner uses ethene as its fuel. The stoichiometric combustion equation of ethene is given by C2H4+3O2 → 2CO2 + 2H2O (a) If eight tonnes of ethene is burnt at one instance, how many tonnes of carbon dioxide is produced? (Hint: the atomic masses are C:12, Н:1, О:16) (b) If insufficient oxygen is supplied to the ethene burner and only carbon monoxide is produced instead of carbon dioxide. Derive the combustion equation (c) The ethene burner supplies a total annual household heat requirement of 3000 kWh per year. Calculate the required ethene supply in kilograms, assuming that it produces 0.28 kg CO2/ kWh
