Solution:
Mn+7O-24- + C+2N-3- → Mn+4O-22 + C+4N-3O-2-
O:C+2N-3- → C+4N-3O-2- + 2e- (C)
R:Mn+7O-24- + 3e- → Mn+4O-22 (Mn
O:C+2N-3- → C+4N-3O-2- + 2e-
R:Mn+7O-24- + 3e- → Mn+4O-22
3C+2N-3- + 2Mn+7O-24- + 6OH- + 6e- + 4H2O → 3C+4N-3O-2- + 2Mn+4O-22 + 6e- + 8OH- + 3H2O

3*1 C 3*1
3*1 N 3*1
2*1 Mn 2*1
9 O 9
1*2 H 2*1
