Question

What is the balanced equation when ammonium nitrate decomposed to form nitrogen, oxygen, and water vapor?

Answer 1

Write the reactant and products-

NH4NO3 --> N2 + O2 + H2O

2N --> 2N

4H --> 2H not balanced

3O --> 3O

Balance the H

NH4NO3 --> N2 + O2 + 2H2O

2N --> 2N

4H --> 4H

3O --> 4O not balanced

Double everything except O2

2NH4NO3 --> 2N2 + O2 + 4H2O

4N --> 4N

8H --> 8H

6O --> 6O
