Which gas makes up the largest amount of smog around cities? sulfur oxides carbon dioxide carbon monoxide nitrogen oxides

sulfur oxides

Explanation:

Smog is a kind of severe air pollution which results due to accumulation of pollutants like nitrogen oxides, ozone, smoke, sulphur oxides and other particulates. These pollutants are added to the atmosphere through coal combustion, industrial emission, fires in agriculture field and forests and lastly because of photochemical reactions.

Among the gaseous pollutants the sulfur oxides are present in high amount as compared to other gases. As the sulfur oxides are released by the burning of fossil fuels. These oxides are the reducing agents which reacts with the oxygen present in the atmosphere result in the formation of a photochemical smog.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
