Measuring the Rate of Reactions between Magnesium and Sulphic Acid
1,111 words, approx. 4 pages
 An official GCSE-style essay on the effect of changing concentrations of sulfuric acid on reaction rates, written in the correct GCSE chemistry format. Covers pre-experiment notes (aim, background information, fair test, and prediction) and the post-experiment notes (conclusion, graph analysis, and evalution). Does not include notes on the actual experiment, as these are specific to the individual experiments.

Chemistry Combustion of Alcohols
1,051 words, approx. 4 pages
 Provides the details of an experiment testing how change in energy release relates to the increase of the number of carbon atoms. Proposes the hypothesis that the longer the hydrocarbon chain, the longer the hydrocarbon will burn for. This is because the longer chains have more C atoms so they will take longer to burn as there are more bonds to break.

Rate of Reaction- Sodium Thiosulfate and Hcl
796 words, approx. 3 pages
 Study of rate of reaction between Sodium Thiosulfate and HCl, GCSE coursework. Identifies that the rate is slower when diluted because the water particles force the sodium thiosulfate particles to become more dispersed and so there are less successful collisions at their activation energy meaning it takes longer for the sulphur particles to be produced and thus it takes longer for the solution to turn cloudy.
