Hello, I need a some help with homework. My teacher considers this the "mother of all equations" and she gave it to us to solve...
I need to balance the following equation, charges included, this reaction takes place in an aqueous solution.

[Cr(N₂H₄CO)₆]₄[Cr(CN)₆]₃ + KMnO₄ + H₂SO₄ =(this is an arrow)= K₂Cr₂O₇ + MnSO₄ + CO₂ + KNO₃ + K₂SO₄ + H₂O

Any help at all would be greatly appreciated! Thanks so much

Yeh, dont think you wanna do that one by hand

I used the online balancer, and got this as an answer:
10 [Cr(N₂H₄CO)₆]₄[Cr(CN)₆]₃ + 1176 KMnO₄ + 1399 H₂SO₄ = 35 K₂Cr₂O₇ + 1176 MnSO₄ + 420 CO₂ + 660 KNO₃ + 223 K₂SO₄ + 1879 H₂O
