Write the half reactions and the balanced

Question

equation for the galvanic cell
Hg(ℓ)| Hg2+
2
(aq)||
MnO−
4
(aq), Mn2+(aq), H
+(aq)| Pt(s).
What is the smallest possible integer coef-
ficient of H+(aq) in the combined balanced
equation?

Answer 1

Also...
Hg2(2+) + 2e- >> Hg2(2+) +0.92V
Mn(2+) + 2e- >> Mn -1.18V

Answer 2

lol idk im trying to do the same problem

Answer 3

Don't cheat!
