a) what element is reduced and what is its charge before and after?
b) what element is oxidized and what is its charge before and after?
a) what element is reduced and what is its charge before and after?
b) what element is oxidized and what is its charge before and after?
Expert's answer
2Al + 3Ag2S → 6Ag + Al2S3
a) Silver is reduced. Ag+ + 1e → Ag0; its charge is +1 before and becomes zero after.
b) Aluminum is oxidized. Al0 – 3e → Al3+; its charge is zero before and becomes +3 after.
a) Silver is reduced. Ag+ + 1e → Ag0; its charge is +1 before and becomes zero after.
b) Aluminum is oxidized. Al0 – 3e → Al3+; its charge is zero before and becomes +3 after.
