Here are the answers translated into English: i) Name: (I) Gas P: Carbon monoxide* (CO) (II) Liquid R: Sulphuric acid* (H_2SO_4) (III) Residue S: Insoluble impurities* ii) The role of coke in this process is as a reducing agent. It removes oxygen from zinc oxide (ZnO) and converts it into zinc (Zn). iii) The main impurity removed in the separation chamber is iron or lead. iv) Write the equation for the reaction that occurs in the: (I) Roaster: 2ZnS_(s) + 3O_2(g) → 2ZnO_(s) + 2SO_2(g) (II) Reaction Chamber II: ZnO_(s) + C_(s) → Zn_(g) + CO_(g) v) Write the equation for the reaction that occurs between zinc metal and liquid R: Zn_(s) + H_2SO_4(aq) → ZnSO_4(aq) + H_2(g) vi) Calculate the mass of zinc sulphide: Step 1: Find the mass of zinc sulphide in the ore. Mass of zinc sulphide = 45\% × 250 kg Mass of zinc sulphide = 0.45 × 250 kg = 112.5 kg Step 2: Convert the mass to grams. Mass of zinc sulphide = 112.5 kg × 1000 g/kg = 112500 g vii) One commercial use of zinc metal is: • To make alloys such as brass. • For galvanizing (coating iron with zinc to prevent rust).
