# How do you write a chemical equation to represent "Gaseous ammonia reacts with gaseous oxygen to form gaseous nitrogen monoxide and gaseous water"?

$4 N {H}_{3} \left(g\right) + 5 {O}_{2} \left(g\right) \rightarrow 4 N O \left(g\right) + 6 {H}_{2} O \left(g\right)$
Is this balanced? Can you write redox half equations? What is the oxidation state of $N$ in nitrous oxide? What is species is oxidized and what species is reduced?
