Air is a mixture of several gasses...
78% Nitrogen.
21% Oxygen.
The final 1% is a mix of other gases including the "Inert Gases", and about 0.04% Carbon Dioxide (CO2)
Air also carries dust, pollen, and can carry viruses and bacteria.
As per my knowledge pure substance does not have anything else added to it. Air and water are pure substances that exist in nature. A pure substance cannot be taken apart to locate more substances.
Chemical materials (pure or impure) can be pollutants for waters, soils and air.
Most substances around us are mixtures, rather than pure substances. Mixtures are composed of two or more substances that are physically combined and can be separated by physical means, while pure substances are made up of only one type of particle. Examples of mixtures include air, sea water, and soil.
No. To start with, air is not a pure substance, and mixiong it with something else just makes it worse.
pure are you dumb or something
Pure substances are divided into elements and compounds.
Water, salt water, and oxygen are pure substances because they consist of only one type of molecule. Tea is a mixture of different substances, including water and various phytochemicals. Copper and brass are chemical compounds made up of multiple elements, making them impure substances. Air is a mixture of gases, with nitrogen and oxygen being the main components.
the different between pure and impure is: 1.pure:means one kind of one thing for example:pure oxygen means only the element oxygen but in the air we have lots of elments beside the air like hydrogen ,nitrogen...etc 2.impure:the opposite from the pure :P
Salt water Ethanol Air Sugar solution Pure gold
Practically (exceptions exist) all known substances can be obtained in a pure fom.
They are both compounds; They both have more than 2 atoms or substances
Compounds and solutions are pure substances
