10 [Cr(N2H4CO)6]4[Cr(CN)6]3 + 1176 KMnO4 + 1399 H2SO4 → 35 K2Cr2O7 + 1176 MnSO4 + 660 KNO3 + 223 K2SO4 + 420 CO2 + 1879 H2O

This is an oxidation-reduction (redox) reaction:

1176 MnVII + 5880 e- → 1176 MnII (reduction)

180 CII - 360 e- → 180 CIV (oxidation)

240 CIII - 240 e- → 240 CIV (oxidation)

660 N-III - 5280 e- → 660 NV (oxidation)
