Answer» Correct Answer - D `MnO_(4)^(-) + 8H^(+) + 5e^(-) to Mn^(2+) + 4H_(2)O xx 2` `" " C_(2)O_(4)^(2-) to 2CO_(2) + 2e^(-) xx 5` `bar(MnO_(4)^(-) + 5Cr_(2)O_(4)^(2-) + 16H^(+) to 2Mn^(2+) + 10 CO_(2) + 8H_(2)O` Thus, the coefficients of `MnO_(4)^(-), C_(2)O_(4)^(2-)` and `H^(+)` in the above balance equation respectively are 2,5, 16. |
