for complete combustion. Recap the differences between complete and incomplete combustion write balanced chemical equations for complete and incomplete combustion reactions The internal combustion engine produces a number of pollutants including NOx, CO, carbon and unburned hydrocarbons. These gaseous pollutants from internal combustion engines can be removed using catalytic converters. Combustion of hydrocarbons containing sulfur to sulfur dioxide that causes air pollution. Students should be able to explain why sulfur dioxide can be removed from flue gases using calcium oxide or calcium carbonate. 5 Measuring energy when alkanes burn Use calorimetry to measure the energy changes during the combustion of n hexane, heptane and octane and calculate the enthalpy change for each. describe how to carry out a practical investigation to measure the energy released when alkanes burn calculate the enthalpy change from experimental data calculate the measurement uncertainties and identify the systematic errors 6.3 6 Problems with alkane combustion Explore the different products formed by the internal combustion engine, the problems they cause and ways to limit their impact. Name the pollutants produced by the internal combustion engine and describe the problems they cause. explain how catalytic converters remove the pollutants from the internal combustion engine explain why sulfur dioxide can be removed from flue gases using calcium oxide or calcium carbonate 6.4
