For the redox reaction
MnO\(_4^{−}\) + C2O\(_4^{2−}\) + H+ \(\longrightarrow\) Mn2+ + CO2 + H2O
The correct coefficients of the reactants for the balanced equation are
1
MnO\(4^{−}\) - 16, C2O\(4^{2−}\) - 5, H+ - 2
2
MnO\(4^{−}\) - 2, C2O\(4^{2−}\) - 5, H+ - 16
3
MnO\(4^{−}\) - 5, C2O\(4^{2−}\) - 16, H+ - 2
4
MnO\(4^{−}\) - 2, C2O\(4^{2−}\) - 16, H+ - 2
