The combustion of hydrocarbon fuels releases energy (1 mark). During combustion, the carbon (1 mark) and hydrogen (1 mark) in the fuels are oxidised. The complete combustion of a hydrocarbon produces carbon dioxide (1 mark) and water (1 mark).

These lesson plans and worksheets are for AQA-C1-4-Crude oil and fuels. Includes lessons on, Crude oil, fractional distillation, burning fuels, cleaner fuels, alternative fuels, biodiesel and hydrogen fuel. Also included is a revision lesson and end of Hot crude oil vapour is pumped into the bottom (the hottest part) of the fractionating column. As crude oil is a mixture of hydrocarbons, as the vapour rises, and the temperature decreases different hydrocarbons with high-low boiling points condense and are pumped out of the column. Crude oil is a finite resource. Petrol and other fuels are produced from it using fractional distillation. Cracking is used to convert long alkanes into shorter, more useful hydrocarbons. The unit studies the composition of crude oil through to its separation into fractions, and thereafter into an individual study of the alkanes, as the starting point for gaining an understanding of the properties of molecules in an homologous series.
