This program explains the essential features of redox reactions and their importance both in nature and in industry. It explains what a redox reaction is, discusses oxidation numbers and how they are used, illustrates how a redox reaction can be seen as the sum of two halves, and teaches how to balance equations in redox reactions. The program presents an example of the combustion of methane.
