Using the steps below how do you balance the oxidation/reduction reaction

In Acidic solution:
H2C204 (ag) + Mno, (aq)
Mn2* (ag) + Co3 (g)
(acidic)
1.
Write the two half- reactions (Oxidation and reduction reaction)
2.
Balance the atoms undergoing oxidation and reduction/ all other atoms other than
"о" and "H"
3.
Balance atoms and charges in each half-reaction.
Use H20 to balance o atoma.
a.
b.
Use H* to balance H atoms
C.
Use e to balance positive charges
4. Multiply each half-reaction by some integer so the the number of e-lost in the
Oxidation half-reaction equals the number of e gained in the Reduction half-
reaction
5.
Add the half - reactions together, canceling species that appear on both sides.
The e must completely cancel and not be present in the end.
