Chapter 10 Chemical Reactions - Glendale Community College
web.gccaz.edu10.9 Redox Reactions Many single replacement, combination, decomposition and combustion reactions are also redox reactions. Redox is short for reduction and oxidation. Reduction is when an element’s charge goes down and oxidation is when an element’s charge goes up. Note you can’t have reduction without oxidation and vice versa.
