`1.The oxidation half equation can be written as-
here is a transfer of 2 electrons occurs.
as it can be computed from that there is the charge on the left is 0, and the charge on the right is 2 = +2, and so the magnitude of the charge difference is (0-2) = 2
hence to balance we required 2 electron.
2.The reduction half -equation can be written as-
Here is a transfer of 3 electrons occurs.
To have the same number of electrons in both half-reactions, multiply the oxidation reaction by 3 and multiply the reduction reaction by 2.
So are transferred in the overall reaction.
