Air is a mixture whereas water is a compound explain

Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Example: Air

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water

Air is a mixture of various gases , dust particles and water vapors which do not react chemically and thus the constituents retain their chemical properties. Water is a compound which is formed by chemical combination of hydrogen and oxygen which lose their individual chemical properties.
