**Nitrogen Dioxide and Its Role in Smog and Acid Rain**A common pollutant in smog is nitrogen dioxide, NO₂. This gas has a reddish-brown color and contributes to the red-brown hue associated with this type of air pollution. In addition to its role in smog, nitrogen dioxide is a precursor to acid rain. When rain interacts with air containing NO₂, it dissolves and undergoes the following chemical reaction:\[ 3\text{NO}_2(g) + \text{H}_2\text{O} \rightarrow \text{NO}(g) + 2\text{H}^+(aq) + 2\text{NO}_3^-(aq) \]**Question:**In this reaction, which element is reduced and which is oxidized?- H is both reduced and oxidized.- O is oxidized and H is reduced.- O is oxidized and N is reduced.- N is both reduced and oxidized.- N is oxidized and H is reduced.- N is oxidized and O is reduced.**Explanation:**This question explores the concepts of reduction and oxidation (redox reactions) in a chemical context. Understanding which elements gain or lose electrons will help in identifying the changes in oxidation states.

A pollutant in smog is nitrogen dioxide, NO₂. The gas has a reddish brown color and is responsible for the red-brown color associated with this type of air pollution. Nitrogen dioxide is also a contributor to acid rain because when rain passes through air contaminated with NO2, it dissolves and undergoes the following reaction: 3NO2(g) + H₂O → NO(g) + 2H*(aq) + 2NO3(aq). In this reaction, which element is reduced and which is oxidized? OH is both reduced and oxidized. OO is oxidized and H is reduced. O is oxidized and N is reduced. ON is both reduced and oxidized. ON is oxidized and H is reduced. ON is oxidized and O is reduced.
