For the redox reaction MnO4- + C2O42- + H+ → Mn2+ + CO2 + H2O
The correct coefficients of the reactants for the balanced reaction are:
MnO4- = 2 C2O42- = 5 H+ = 16
MnO4- = 16 C2O42- = 5 H+ = 2
MnO4- = 5 C2O42- = 16 H+ = 2
MnO4- = 2 C2O42- = 16 H+ = 5
The balanced redox reaction is
2 MnO4- + 5C2O42- +16 H+ → 2Mn2+ + 10 CO2 + 8H2O
For the redox reaction MnO−4+C2O−24+H+⟶Mn2++CO2+H2O the correct coefficients of the reactants MnO−4, C2O2−4 and H+ for the balanced reaction are
For the redox reactionMnO−4+C2O−24+H+⟶Mn2++CO2+H2Othe correct coefficients of the reactants MnO−4, C2O2−4 and H+ for the balanced reaction are
