Final answer:
The balanced chemical equation is 2NO + 2O3 → 2NO2 + O2.
Step-by-step explanation:
The balanced chemical equation for the reaction between nitrogen monoxide (NO) and ozone (O3) is:
2NO + 2O3 → 2NO2 + O2
In this reaction, two molecules of nitrogen monoxide react with two molecules of ozone to produce two molecules of nitrogen dioxide and one molecule of oxygen gas.
