Question

Water is a compound while air is a mixture. Explain.

Answer 1

Water is a compound because :

(1) Water is made up of 2 elements in a fixed ratio.

(2) Its constituents can be separated only by chemical or electrochemical reactions.

(3) Its formed by reaction between hydrogen & oxygen with a chemical bond.

(4) Water has totally different properties from 2 elements.

(5) It has a fixed boiling point.

Air is a mixture because :

Air can be separated into its constituents such as oxygen, nitrogen etc. by fractional distillation of liquid air.

Air shows the properties of all the gases present in it.

Answer 2

Answer:

Here is your answer....

MIXTURE: Is a substance in which two or more than two substances combine together in a variable ratio. Eg: Air, Fizzy drink etc.

COMPOUND: Is a substance in whichever two or more than two substances combine together in afixed ratio. Eg: H2O, CO2 etc.

From above definition it is clear that what is compound and what is mixture?

Air contain number of gases in any ratio hence it is mixture while water contain only two atom i.e. hydrogen and oxygen in 2 : 1 ratio which is definite hence it is compound not a mixture..

Hope its helpful to u....

thank u.....
