No, smog is not a pure substance. Smog is a type of air pollution that typically consists of a mixture of various pollutants, including smoke, fog, and chemical compounds such as sulfur dioxide, nitrogen oxides, and particulate matter. These components come from multiple sources, including vehicle emissions, industrial discharges, and natural sources, so smog is considered a heterogeneous mixture rather than a pure substance.
