Which coefficients correctly balance the following equation:

NH4NO --> N2 + H2O
1, 2, 2
2, 1, 1
2, 2, 2
1, 1, 2

4 answers

1, 1, 2
I have absolutely no idea I didn't pay attention is this unit.
AAAaannndd the bot gets it wrong yet again!
1,1,2 does certainly NOT balance the equation!
NH4NO → N2 + 2H2O
1 O on the left, 2 O on the right

In fact, the equation as written cannot be balanced.
It should be
NH4NO2 → N2 + 2H2O
so, 1,1,2
