Concept explainers
(a)
Interpretation:
Near to which cities the air hazardous to one or more groups has to be identified.
Concept introduction:
Stratosphere:
It is found below the mesosphere layer in which the concentration of ozone and other gases are high. The increasing temperature for this layer with respect to increasing height is due to the presence of high concentration of ozone and other gases in it.
The increased temperature is due to the response of UV radiation from sun and hence ozone is formed due to this reaction and the use of ozone is that it prevents the UV radiation from the sun which is actually harmful.
Chlorofluorocarbon (CFC): They are compounds that contain only carbon, fluorine and chlorine with it. They are gases can be easily liquefied, have little ability to react readily, are non-poisonous and do not catch fire easily.
Nitrogen oxides: They are binary compound that contains only oxygen and nitrogen with them.
Ozone: It is an allotrope of oxygen with chemical formula
Ozone layer depletion is the destruction process of ozone layer by various chemicals mainly chlorofluorocarbons (CFC).
(b)
Interpretation:
Time at which the ozone level peak has to be identified.

Chemistry In Context
- More ozone is found in the stratosphere than the troposphere. Why is this?arrow_forwardWhy is ground level ozone most likely to reach its highest concentrations on hot, sunny days during periods of heavy traffic in large cities?arrow_forwardIn which region is ozone a pollutant? In which region does it filter UV solarradiation?arrow_forward
- When ozone levels in urban areas reach unhealthy levels, residents are typically urged to avoid refueling their cars during daylight hours. Explain how this might help to reduce smog formation.arrow_forwardIf gasoline produces only carbon dioxide and water when it burns completely, why is automobile exhaust a source of air pollution? List the pollutants formed and briefly describe their impact.arrow_forwardWhy does ozone deplete severely over Antarctica each October, but not over other areas of the planet?arrow_forward
