Morning commuter traffic in cities contributes to ____ smog. In this type of air pollution, a mixing of ____ from certain plants
azamat

Answer:

photochemical

hydrocarbon

Explanation:

Morning commuter traffic in cities contributes to<u> photochemical</u> smog. In this type of air pollution, a mixing of <u>hydrocarbons</u> from certain plants, nitrogen oxides from cars, and UV radiation from the sun results in a variety of pollutants, such as ground-level ozone, which can cause coughing and breathing problems.

<em>Photochemical smogs are caused by the photochemical reaction of hydrocarbon and nitrogen oxides in the lower atmosphere with sunlight playing a major role. The reaction of the hydrocarbon with the nitrogen oxide in the presence of light leads to the evolution of ozone gas while nitrogen oxide has the capacity to react with the sunlight on its own to produce nitrogen dioxide. This result in the formation of smog</em>
