Oxygen:

A gas that you cannot see, taste or smell. Plants and animals cannot live without oxygen.

Carbon dioxide is an acidic colorless gas with a density about 53% higher than that of dry air.

Nitrogen is the chemical element with the symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772.

Answer 2

=Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.

=Carbon dioxide is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas.

=a gas that has no colour, taste or smell. Nitrogen forms about 80% of the air around the earth
