Following question I need help with part b) Please verify my answer for part a) too if possible.

Consider the following reaction for silver tarnishing:
3Ag2S(s) + 2Al(s) -> 6Ag(s) + Al2S3(s)

a. State the oxidation number for each element in the reaction.

3Ag2S(s) + 2Al(s) -> 6Ag(s) + Al2S3(s)
(+1)+(-2)+(+3) -> (+1)+(+3)+(-2)
verify these please

b. Identify the oxidized reactant and the reduced reactant.

Please help me with b) above....
