Question

Air is considered a mixture .Give three reason to support your answer.

Answer 1

What we define as “air” is a mixture, because it has many gases in it. Air is made up of a large number of different gases, but primarily nitrogen(N) at about 78%, oxygen(O) at about 21%, argon (Ar) at about .93%, and carbon dioxide(CO2) at about 0.03%. The scientific difference between mixture and compound is that a mixture can be separated by physical means, such as breathing or with a jar. Compounds require chemical means to break apart; for example CO2.
