Please Mark the answer as brainliest
Explanation
The reaction is similar to esterification reaction. When ethyl hydrogen sulphate react with ethyl alcohol it produces diethyl ether.
Nitrogen N2 is not an air pollutant. Because Nitrogen makes up 78% of our atmosphere.
CFCs and other halogenated ozone depleting substances (ODS) are mainly responsible for manmade chemical ozone depletion. (So the answer is CFC)
Aspirin is an antipyretic.
Solid
