Would these be a redox reaction?
CaO(s) + H2O(l) = Ca(OH)2(aq)
2FeSO4(aq) + 3H2O2(aq) = Fe2O3(s) + 3H2O(l) + 2SO42-(aq)

#1 is not a redox reaction because the charges don't change, however #2 would be because the charges do change and you can draw from it a reduction reaction and an oxidation reaction.

oops i meant the oxidation numbers...Sorry!!
