Answer:
4NH₃ + 5O₂ —> 4NO + 6H₂O
Step-by-step explanation:
NH₃ + O₂ —> NO + H₂O
The above equation can be balance as follow:
NH₃ + O₂ —> NO + H₂O
There 3 atoms of H on the left side and 2 atoms on the right side. It can be balance by 4 in front of NH₃ and 6 in front of H₂O as shown below:
4NH₃ + O₂ —> NO + 6H₂O
There are 4 atoms of N on the left side and 1 atom on the right side. It can be balance by putting 4 in front of NO as shown below:
4NH₃ + O₂ —> 4NO + 6H₂O
There are 2 atoms of O on the left side and a total of 10 atoms on the right side. It can be balance by putting 5 in front of O₂ as shown below:
4NH₃ + 5O₂ —> 4NO + 6H₂O
Thus, the equation is balanced.
