Using the reaction provided, assign the oxidation state of each atom in the reaction and determine which species are being oxidized and which are being reduced in the overall reaction. Concept introduction: An ore is a complex mixture of metal-containing mineral and economically worthless material called gangue, consisting of sand, clay, and other impurities. Extracting a metal from its ore requires three main steps: (1) concentration of the ore, and if necessary, chemical treatment prior to reduction; (2) reduction of the mineral to the free metal; (3) refining or purification of the metal. To classify: Which elements are being oxidized/reduced and which species arethe oxidizing/reducing agents.
