1) Conduct the experiment on a balance. This enables you to watch the mass changing as the reaction proceeds. Only suitable for reactions where a gas is produced – the gas escapes the vessel and the mass decreases. 2) Collect gas in a syringe or cylinder. You can use a stopwatch to see how much gas is produced with time. Only suitable

When a sodium thiosulfate solution (Na 2S2O 3(aq)) is added to hydrochloric acid, sulfur is formed. 1 What would you observe during the reaction? How could you set up the experiment to measure the reaction time for a given combination of thiosulfate and acid solutions? 2 What other products are formed?
Task: Design an experiment to allow you to measure the heat efficiency of two potential fuels; liquid paraffin or paraffin/wax tablets. Also explain what a variable is, and what variables exist in this experiment.
