   Plan an experiment to test the hypothesis “the higher the temperature, the faster the rate of reaction”. Measure the rate of reaction by adding a set amount of metal to set type, volume and concentration of acid and time how long it takes to stop fizzing. Repeat the experiment at 5 different temperatures. Determine.

   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?

   What is exothermic reaction?

   • ctions that release heat are called exothermic. When the reaction is complete, the hydrogen will have escaped into the room. The beaker will contain magnesium chloride dissolved in water and excess hyd ochloric acid. In order to determine the mass of magnesium

   What is the most common error in a chemistry test?

   • The commonest error was to refer to concentration rather than extent of ionisation. Candidates should be advised to try to write with greater precision, as many suggested that it was the ions which ionised rather than the molecules.

   What should a candidate know about experimental determinations of energy changes?

   • Candidates should familiarise themselves with the experimental procedure in experimental determinations of energy changes, such as that referred to in Question 6. This includes familiarity with sources of error and their correction.

   What are the most common errors in atomic chemistry?

   • The commonest errors were to suggest 82 electrons through not taking into account the ionic charge or to add the mass number to the atomic number to obtain the number of neutrons. A significant number of candidates inverted the number of electrons and neutrons giving 125 electrons and 80 (or 82) neutrons.
