Topic: going in circles when balancing equation (Read 38383 times)

HNO₂ + 3HN₃ -> 5N₂ + 2H₂O

4HNO₂ + 2HN₃ -> 5N₂O + 3H₂O

so, for example:

4169HNO₂ + 4637HN₃ -> 5105N₂ + 3935N₂O + 4403H₂O

is correctly balanced

As lemonoman said, I wonder how many times in in my life (which is most likely going to be a chemist-life

) I'll have to balance such equations...

That's a trick that have nothing to do with chemistry. But looks very seriously chemically

You may generate such equations by yourself, just follow description from my lecture on balancing failures

Another interesting one

Pb(NO₃)₂ + Cr(MnO₄)₂ = Pb₃O₄ + Cr₂O₃ + MnO₂ + NO

Apart from Borek's monster-equations

, This is one that I had to balance at school yesterday:

P + KOH + H₂O ? PH₃ + KH₂PO₄
