Join Yahoo Answers and get 100 points today. Why is an alloy harder than a pure metal? Looking at the equation, there must be a significantly smaller number of #MnO_4# ions than #H^+# ions (otherwise there would be far too many oxygen atoms for the carbon and hydrogen atoms to balance them out in the form of #CO_2# and #H_2O#), so (1) is the only choice left. Half-equations MnO4 - (aq) -> MnO2 (s) C2O4-2 (aq) -> CO2 (g) 2. I can understand redox equations of the following form, I break these down into half equations and combine them. 1:19. The net effect is that you end up adding 1 H atom to the side that lacks a H atom. First, I found the oxidation numbers for the overall equation, and I think that $\ce{C2O4^2-}$ is the reducing agent because $\ce{C}$ is losing charge from +3 to +4, I just don’t know how to use that to balance … ---------------------- -------------------------- -------------------------, 8H2O + 2MnO4- + 5C2O4^2- --> 2Mn2+ + 10CO2 + 16OH-, if we modify the balance charge by adding H+ not OH- => MnO4- + 5e- + 8H+ --> Mn2+.
