(4) NH3+02- NO+H2O
balance the equation

4NH₃ + 5O₂ —> 4NO + 6H₂O

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.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
