We're given the following reaction:

___ NH3 + ____O2 → _____ NO + ______ H2O

Recall that when balancing chemical equations, we have to make sure that the number of elements on both sides is equal with the lowest whole number coefficients.

Reaction 1:

 __ NH3 + ___O2 → ___ NO + __ H2O N      1H      3O      2 N      1H      2O      1
