When nitrogen dioxide $\left({\mathrm{NO}}_2\right)$ gas combines with water vapor $\left({\mathrm{H}}_2\mathrm{O}\right)$ in the air, it forms aqueous nitric acid $\left({\mathrm{HNO}}_3\right)$, which causes acid raid, and nitrogen oxide $(\mathrm{NO})$ gas. a. Write the balanced chemical equation. ${\mathrm{NO}}_2+{\mathrm{H}}_2\mathrm{O}\backslash \backslash$ b. How many grams of ${\mathrm{HNO}}_3$ are produced when $60.0\mathrm{g}$ of ${\mathrm{NO}}_2$ completely reacts?
