mosesmaluki345@gmaik.com, let's knock this out. Here are the answers to your questions: a) Name and write the formulae of the major ore for this process. Name: Bauxite Formula: Al_2O_3 · nH_2O b) Write the equation of the reaction taking place at the: Anode: 2O^2-(l) + C(s) CO_2(g) + 4e^- Cathode: Al^3+(l) + 3e^- Al(l) c) Formula of the molten alumina: Al_2O_3 d) Explain the role of cryolite added to molten alumina: Cryolite (sodium hexafluoroaluminate, Na_3AlF_6) is added to lower the melting point of alumina from approximately 2072\,^ to about 950\,^, and also to increase the electrical conductivity of the mixture. e) It is cheaper to recycle aluminum other than to extract it. Explain: Recycling aluminum requires significantly less energy (about 5% of the energy needed to extract new aluminum) and reduces production costs, environmental pollution, and waste disposal. f) Explain why graphite anodes must be replaced after some time: Graphite (carbon) anodes react with the oxygen produced at the anode during electrolysis. The oxygen reacts with carbon to form carbon dioxide, thus consuming the anodes gradually. C(s) + O_2(g) CO_2(g) g) State one property of aluminum that makes it suitable for wrapping food: Aluminum is lightweight, non-toxic, resistant to corrosion by many food acids and bases, and is highly malleable, allowing it to be easily shaped into thin foil without breaking.
