Review Problem 5.042 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) + H20 - NO(g) + 2H+ (aq) + 2NO3- (aq). In this reaction, which element is reduced and which is oxidized? H...
