Most fuels, including coal, contain carbon and/or hydrogen and may also contain some sulfur. The gases released into the atmosphere when a fuel is burned may include carbon dioxide, water vapour, carbon monoxide, sulfur dioxide and oxides of nitrogen. Solid particles and unburned hydrocarbons may Describe how carbon monoxide, soot (carbon particles), sulfur dioxide and oxides of nitrogen are produced by burning fuels Predict the products of combustion of a fuel given appropriate information about the composition of the fuel and the conditions in which it is used. WS 1.2 1 Write word equations for the complete and incomplete combustion. Describe how the following pollutants are made in combustion: carbon dioxide carbon monoxide soot water vapour sulfur dioxide nitrogen oxides. Describe the products of different fuels from complete and incomplete combustion. Demonstrate to students the emissions from a car exhaust by showing them a white sock that has covered the exhaust pipe of a running car for 5 minutes (if possible, use one sock on a diesel, one on a petrol car). Students can build models of pollutants using Lego or plasticine and break them apart to form products of complete combustion: Video clips YouTube: YouTube:
