Answer: 4 NH₃ + 5 O₂ → 4NO + 6 H₂O
Step-by-step explanation:
If we write out the chemical symbols for the molecules expressed in the question, along with the moles we get the following equation:
4 NH₃ + 5 O₂ → 4 NO + 6 H₂O
To know if the equation is balanced we can compare the Reantact side to the Product side for each element. If the equation is balanced, they would be equal.
Reactant Product
N 4 4
H 12 12
O 10 6+4 = 10
∴ the equation is balanced.
