Balancing chemical equations

NH3 + 5O2~4N O + H2O

4NH₃ + 5O₂ → 4NO + 6H₂O

Explanation:

Chemical equation:

NH₃ + O₂ → NO + H₂O

Balanced chemical equation:

4NH₃ + 5O₂ → 4NO + 6H₂O

Steps:

NH₃ + O₂ → NO + H₂O

N = 1 N = 1

H = 3 H = 2

O = 2 O = 2

NEXT:

2NH₃ + O₂ → NO + H₂O

N = 1*2=2 N = 1

H = 3*2=6 H = 2

O = 2 O = 2

NEXT:

2NH₃ + O₂ → 2NO + 3H₂O

N = 1*2=2 N = 1*2=2

H = 3*2=6 H = 2*3=6

O = 2 O = 3+2 = 5

Now we will balance the oxygen:

2NH₃ + 5/2O₂ → 2NO + 3H₂O

N = 1*2=2 N = 1*2=2

H = 3*2=6 H = 2*3=6

O = 2*5/2 = 5 O = 3+2 = 5

2*2NH₃ + 2*5/2O₂ → 2*2NO + 2*3H₂O

4NH₃ + 5O₂ → 4NO + 6H₂O
