2. Use oxidation numbers to determine which of the following chemical equations represent a redox reaction. For all that ARE redox reactions, indicate the oxidizing agent, the reducing agent, the element being oxidized, and the element being reduced. (a) HCl(g) + NH,(g) → NH,CI(s) (b) SiCl,(1) + 2 Mg(s) → 2 MgCl,(s) + Si(s) (c) CO(g) + H,O(g) → CO,(g) + H,(g)
