Chapter 4.5

Redox Reactions and Balancing with Half-Reactions

Name: Redox Reactions and Balancing with Half-Reactions
Description: Iron rusts, batteries die, and a match burns for the same reason: electrons changed owners. Split any such reaction into the half that gives and the half that takes, and balancing becomes bookkeeping.
