Air is a mixture whereas water is a compound explain

Answers

Answer:

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 H_2O

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.

Air is a mixture as in it has different types of gases mixed in the air such as Nitrogen, Oxygen, and Carbon Dioxide, but none of these are bonded or fused together. Water is a compound of 1 Oxygen and 2 Hydrogen molecules bonded together, as in permanently together. You can think of Air as a bowl of trail mix, everything in there is separable, and a compound as in something inseparable (Unless done using scientific methods).
