Answer to Question #144135 in Physical Chemistry for Shamen
Question #144135
How to balance the following equation? Including steps
aC2H4 + bH2O +cH+ + 2MnO4- ---> dC2H6O2. + eMn2+
aC2H4 + bH2O +cH+ + 2MnO4- ---> dC2H6O2. + eMn2+
Expert's answer
aC2H4 + bH2O +cH+ + 2MnO4- ---> dC2H6O2. + eMn+2
MnO4- + 5e- + 8H+ = Mn+2 + 4H2O - 2
C2H4 - 2e- + 2H2O = C2H6O2 + 2 H+ - 5
2MnO4- + 16H+ + 5C2H4 + 10H2O = 2Mn+2 + 8H2O + 5C2H6O2 + 10H+
2MnO4- + 6H+ + 5C2H4 + 2H2O = 2Mn+2 + 5C2H6O2
