Question

Balance the following redox equation in acid. In the blank put the correct stochiometric coefficient (0, 1, 2, etc.). (Note: 0 if the species does not appear on that side of the equatio

1-SO3-(ag)+MnO4-(ag)+H+(ag)---->SO4^2-(ag)+Mn2+(ag)+H2O(l)

2- H2O2(ag)+ClO2(ag)+HO-(ag)---> O2(g)+ClO2-(ag)+H2O(l)

Q: In the electrochemical voltaic cell using the reaction, Fe³⁺(aq) +  Cr(s) → Fe(s) + Cr³⁺(aq), match the correct 1/2 reaction that occurs at the anode and cathode.

1/2 reaction occuring at the anode

1/2 Reaction occuring at the cathode

Choices:

A

Fe3+(aq) + 3e−  → Fe(s)
B	Fe3+(aq) → Fe(s) + 3e−
C.	Cr(s) + 3e− → Cr3+(aq)
D.	Fe(s) +  3e−  →  Fe3+(aq)
E.	Cr(s) → Cr3+(aq) + 3e−
F.	Cr3+(aq)  + 3e− → Cr(s)
