Nitrogen dioxide: The formula of nitrogen dioxide is NO2. Nitrogen dioxide is a gaseous air pollutant. It is produced by combustion of fossil fuels. The presence of nitrogen dioxide in air leads to the formation of other air pollutants, like ozone and particulate matter which in turn leads to acid rain. This gas is also the primary pollutant.
These gases mainly include carbon monoxide, nitrogen dioxide and sulphur dioxide doesn't pollute air😊. Oxygen on the other hand, does not cause air pollution and is important for our survival.
No, Soap is a combination of a weak acid (fatty acids) and a strong base (lye), which results in what is known as “alkalai salt,” or a salt that is basic on the pH scale.

Among the given options CO2 (carbon dioxide) doesn't pollute air. We exhale CO2 and it is utilised by plants in photosynthesis
thermal conductivity decrease with the rise in temperture
Because of increase in resistance?
