Consider the reaction Mg reacting with Oxygen (a reaction of metal with non-metal): 2Mg(s) +O2 (g) Æ 2MgO(s) It’s easier to understand the electron transfer when you break up this reaction into half reactions as shown below: 2Mg Æ 2Mg2+ + 4 In this process the Fe 2+ ion is oxidized, but there is no oxygen involved in this reaction. The Ce 4+ ion, which is reduced acts as the oxidizing agent. So oxidation reactions need not involve oxygen. This redox reaction is actually the sum of two separate half-reactions (a reduction half-reaction and an oxidation half-reaction). The general equation for this reaction is: metal + oxygen → metal oxide. Some metals will react with oxygen when they burn. These reactions are called combustion reactions. Two examples of combustion reactions are: Iron reacts with oxygen to form iron oxide: 4 Fe + 3 O 2 → 2 Fe 2 O 3. Magnesium reacts with oxygen to form magnesium oxide: 2 Mg + O 2 → 2 MgO
