Expert Answer
Oxidation number of Mn in
x-8=-1
x=+7
Change of oxidation number of Mn is from +7 to +2
The decrease in oxidation number is=7-2=5
Oxidation number of C increases from +3 to +4.
The change in oxidation number for 1 C atom=4-3=1
The increase in oxidation number for 2 C atom=2
1) To balance the oxidation number-
2) Balance the O atoms by adding 8 water molecules on product side-
3) Balance the H atoms by adding 16 H+ ions to reactant side-
This is the balanced equation.
The simples molar ratio of these reactants is 2:5.
