How to Balance: NH3 + O2 = NO + H2O

In order to balance NH3 + O2 = NO + H2O you'll need to watch out for two things. First, be sure to count all of N, H, and O atoms on each side of the chemical equation. Once you know how many of each type of atom you have you can only change the coefficients (the numbers in front of atoms or compounds) in order to balance the equation. Be careful when counting the Oxygen atoms on the product side of the equation. Don't forget the H2O on the product side of the chemical equation! Drawing/writing done in InkScape on a Wacom tablet..
