QUESTION 1 This questiоn is аbоut the metаl аluminium. a Aluminium is malleable and cоnducts electricity. See diagram 1a in the diagram pdf. The diagram shows the arrangement of the ions in aluminium metal. a(i) Explain why aluminium is malleable. (2) a(ii) Explain why aluminium conducts electricity. (2) b Aluminium cannot be extracted by heating a mixture of carbon and aluminium oxide. Give a reason why heating a mixture of aluminium oxide and carbon does not produce aluminium. (1) c Aluminium is extracted industrially by the electrolysis of molten aluminium oxide Al2O3 at a temperature of about 950 °C. Aluminium metal forms at the negative electrode and oxygen gas forms at the positive electrode. The positive and negative electrodes are made of graphite. See diagram 1c in the diagram pdf. The diagram shows the apparatus used. c(i) Explain how aluminium metal forms at the negative electrode. (2) c(ii) Write an ionic half-equation for the formation of oxygen gas at the positive electrode. ........................... → ........................... (1) c(iii) Suggest why carbon dioxide gas is also produced at the positive electrode. (2) d Aluminium reacts with iron(III) oxide. The reaction is exothermic. The equation for the reaction is 2Al + Fe2O3 → Al2O3 + 2Fe d(i) State how the equation shows that iron(III) oxide is reduced. (1) d(ii) Draw an energy level diagram for the reaction between aluminium and iron(III) oxide. See diagram 1d in the diagram pdf to draw the energy level diagram. (3) [14]
