Sciences P2 Grade 12 QUESTION 5 Thabang investigates the rate at which reactants are used when a certain amount of calcium carbonate reacts with EXCESS dilute hydrochloric acid, The balanced equation for the reaction is: CaCO3(s) + 2HCl(aq) + CaCl(aq) + H,00) + Co (9) He performs two experiments as illustrated in the diagram below. The beakers are identical and the same volume of acid and mass of calcium carbonate are used in both experiments. Beaker 0,1 mol dm HCl(aq) 0.2 mol dm HCl(aq) Caco, granules х 180.00 180,00 Experiment 1 Experiment 2 5.1 write down the NAME and FUNCTION of the apparatus labelled X. (2)​
