QUESTION 4 Mаgnesium cаrbоnаte pоwder reacts with hydrоchloric acid. (a) Complete the equation for this reaction by adding state symbols. (1) (b) A student carried out an investigation to determine the molar volume of carbon dioxide using this apparatus. See addendum Figure 4.1 The student carried out five experiments, adding a different mass of magnesium carbonate each time. The results are shown in the table. See addendum Figure 4.2 (i) Plot a graph of these results. (3) See addendum Figure 4.3 (ii) A student carried out a further experiment using a different mass of magnesium carbonate. Give the volume of gas collected using the inverted measuring cylinder. See addendum Figure 4.4 (1) (iii) Determine the mass of magnesium carbonate added in the experiment in (b)(ii), using your graph. (1) (iv) Calculate the molar volume of carbon dioxide using your answers to parts (b)(ii) and (b)(iii). Give your value to an appropriate number of significant figures and include units. [ Ar values: Mg = 24.3 C = 12.0 O = 16.0 ] (4) (v) The acid must be in excess for each experiment. Calculate the minimum concentration of hydrochloric acid needed for 30 cm3of acid to completely react with 0.25 g of magnesium carbonate. (2) (c) The value of molar volume calculated in (b)(iv) was lower than the student expected. Give two reasons for the value being lower than expected. Assume that the correct amounts of hydrochloric acid and magnesium carbonate were used. (2) TOTAL QUESTION 4: [14]
