Is air and element compound or mixture?
Air is a mixture that contains the elements nitrogen, oxygen and argon, and also the compound carbon dioxide.
Is air a mixture?
Complete step by step answer: Air is considered as mixture for the following reasons: Air can be separated into its components like nitrogen, oxygen, argon and carbon dioxide by the process of fractional distillation of liquid air. 2. Air shows the properties of all the gases present in the atmosphere.
Is air a pure substance or a mixture?
– Air is not supposed to be considered as a pure substance. Because air is a mixture of different gases. – Air mostly contains nitrogen and oxygen in about 78% and 20% respectively. Note: Elements and compounds have a constant composition throughout and can thus be said as pure substances.
Why air is considered to be a mixture?
Air is considered as a mixture because its a mixture of different gases. The composition of air is- 78%Nitrogen, 21%Oxygen and 1% Other inert gases like Hydrogen, Argon , Helium, Neon, etc.
Is the air a solution?
Air is a solution made up of many gases. There is more nitrogen than any other gas in air, so it is considered the solvent in an air solution.
Is an air an element?
Air is one of the four classical elements along with water, earth and fire in ancient Greek philosophy and in Western alchemy.
What is the air or mixture?
air is not a mixture because of scientists freezing it and finding different liquids, it is a mixture because the compounds that make up air e.g. oxygen (o2), Carbon dioxide (co2) and the most important Nitrogen which is an element and makes up 78.09% of air are not chemically bound in the way that compounds are …
Why is pure air a mixture?
Why air is mixture and not a compound?
Air is a mixture and not a compound because: Air does not have a formula like a mixture, while compounds have a fixed formula. When air is formed by gases, there is no energy change. Components of air can be physically separated.
Is air is a mixture or compound give three reason?
Air is considered a mixture because of the following reasons: (i) Air can be separated into its constituents like oxygen, nitrogen, etc., by the physical process of fractional distillation. (iii) Air has a variable composition because air at different places contains different amounts of the various gases.
Is air a compound?
Air is a mixture but not compound. Its constituents can be separated. For example: oxygen, nitrogen etc. Air shows properties same as the constituent gases present in it.
Why air is not a compound but a mixture?
Air is a mixture, but not a compound because air can be separated into different components such oxygen, nitrogen etc through the process of fractional distillation. Also, air shows all the properties of gases present in it.
