N2 + 02--> NO2 forming nitrous oxide

Respuesta :

N2 + 2O2 --> 2NO2

This is correct because you now have the same number of each element. Two Nitrogen, on the left side. So we made two on the right side. But after adding the second to the right side we then had 4 Oxygen on the right side. So we balanced the equation by adding an Oxygen to the left.
