Question

Nitric acid is a component of acid rain that forms when gaseous nitrogen dioxide pollutant reacts with gaseous oxygen and liquid water to form aqueous nitric acid.Write a balanced chemical equation for this reaction.

Answer 1

NO2 + O2 + H2O -> HNO3

Answer 2

4NO2(g) + O2(g) + 2H2O(l) -> 4HNO3(aq)

Answer 3

\(\mathsf {\boxed{4 NO_2 (g) + O_2 (g) + 2 H_2 O (l) \rightarrow 4 HNO_3 (aq.) }}\)
