Answer 2

It appears that you're trying to represent a chemical reaction involving nitrous acid (HNO2) decomposing into nitric acid (HNO3), nitrogen monoxide (NO), and water (H2O). The balanced chemical equation for this reaction would be:

2 HNO2 → HNO3 + NO + H2O

This balanced equation shows that two molecules of nitrous acid (HNO2) decompose to form one molecule of nitric acid (HNO3), one molecule of nitrogen monoxide (NO), and one molecule of water (H2O). The equation is balanced in terms of the number of atoms on both sides of the reaction arrow.
