The mineral bauxite, which is mostly Al2O3, i the principal industrial source of aluminum metal. How much aluminum can be produced from 4.50 ton of Al2O3?
4Al + 3O2 === 2Al2O3 Aluminum and oxygen are of their elemental states, they usually react to type a compound. So it is a redox reaction. Mentioned a different way, the oxidation numbers of aluminum and oxygen start at zero and alter to +3 for aluminum and -2 for oxygen, and that is oxidation and reduction.
