Answer:
2NH4NO3 —> 2N2 + O2 + 4H2O
Explanation:
We begin by writing the skeletal equation as shown below:
NH4NO3 —> N2 + O2 + H2O
The equation can be balance as follow:
There are 4 atoms of H on the left side of the equation and 2 atoms on the right side. It can be balance by putting 2 in front of H2O as shown below:
NH4NO3 —> N2 + O2 + 2H2O
Now we have a total of 4 atoms of O on the left side and 3 atoms on the right side. It can be balance by putting 1/2 in front of O2 as shown below:
NH4NO3 —> N2 + 1/2O2 + 2H2O
Now, multiply through by 2 to clear the fraction as shown below
2NH4NO3 —> 2N2 + O2 + 4H2O
Now the equation is balanced
