Question

Label the oxidizing agent and the reducing agent:
a) P4(s) + 5O2(g) -> P4O10(s)
b) Co(s) + Cl2(g) -> CoCl2(s)
c) Fe2O3(s) + 3CO(g) -> 2Fe(s) + 3CO2(g)
d) PbS(s) + 4H2O2(aq) -> PbSO4(s) + 4H2O(l)

I never learned about oxidation numbers. Thanks!

Answer 1

You never learned about oxidation numbers? You missed an important, fundamental lesson.
