Question

Balance the equation MnO4^- +C2O4^2- +H^+ gives rise to CO2 +Mn^2+ + H2O and determine the coefficient of CO2 and Mn^2+

Answer 1

Answer:

10 and 2 respectively

Explanation:

MnO4- +5e- + 8H+ = Mn2+ + 4H2O]×2

C2O4^-2 = 2CO2+2e-]×5

The overall balanced chemical equation is

2MnO4-+5C2O4^2- +16H+ = 2Mn^2+ +10CO2+ 8H2O
