Guys i am going crazy over this. i think the answer is not right. but can you check it? MnO4-(aq) + H2C2O4(aq) _> Mn2+(aq) + CO2(g) + H2O(l) + H+(aq) choose the correct order of coefficients: a. 2,2,5,6,8,10 b. 2,5,6,2,10,8 c, 2,10,8,5,2,6, d. 10,8,4,5,6,8, e. 1,5,1,10,4,2, ans. E. i my solution: 2(5e-+ 8H+ +Mno4-__> Mn2+ + 4H2o) 1st half reaction 5(H2C2O4__> 2CO2 + 2H+ +2e-) 2nd half reaction adding everything: 10e- + 16H+ +2MnO4- + 5H2C2O4 --> 2Mn2+ + 8H2O + 10CO2 + 10H+ + 10e- now simplyfining: 6H+ + 2MnO4- + 5H2C2O4--> 2Mn2+ + 8H2O + 10CO2 so the coefficient is 6,2,5,2,8,10. but it is not part of the choices. what is wrong?
