Is air a mixture or compound Give 3 reasons? Air is a mixture and not a compound because of following reasons: Air can be separated into its constituents such as oxygen, nitrogen etc. For example: Air supports combustion because of oxygen present in air.
Why is air a mixture not a compound?
19/05/2020 · Air is a mixture and not a compound because of following reasons: Air can be separated into its constituents such as oxygen, nitrogen etc. For example: Air supports combustion because of oxygen present in air. Air has a variable composition because at different places different amount of gases are present in air.
Why does air have a variable composition?
Air is considered a mixture for the following reasons ; Air can be separated into its components like N2, O2, Argon, and CO2 by the process of fractional distillation of liquid air. Air shows the properties of all the gases present in the atmosphere. For example: Oxygen is a good Supporter of combustion. Hence air also is a good supporter of ...
What are the three properties of air?
Air is a mixture and not a compound because of following reasons: Air can be separated into its constituents such as oxygen, nitrogen etc. For example: Air supports combustion because of oxygen present in air. Air has a variable composition because at different places different amount of gases are present in air.
What is the chemical formula of air?
12/12/2014 · Air is a mixture not a compound for following reasons: 1) air can be separated into it constitutes like oxygen, nitrogen etc. by physical process of fractional distillation. 2) error shows the properties of all the gases present in it. 3) air has variable composition. 4) liquid air doesn't have fixed boiling point.
Why air is a mixture give three reasons?
1) air can be separated into it constitutes like oxygen, nitrogen etc. by physical process of fractional distillation. 2) error shows the properties of all the gases present in it. 3) air has variable composition.
Is air a mixture or compound?
Air is a mixture but not compound. Its constituents can be separated. For example: oxygen, nitrogen etc. by physical process.
What is air a mixture of?
Air is mostly gas It's a mixture of different gases. The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.12-Sept-2016
Why air is a mixture not a compound class 9?
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.
Is milk a mixture?
Milk is a mixture of liquid butterfat globules dispersed and suspended in water. Colloids are generally considered heterogeneous mixtures, but have some qualities of homogeneous mixtures as well.
Is air a mixture?
One example of a mixture is air. Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances. Mixtures are unlike chemical compounds, because: The substances in a mixture can be separated using physical methods such as filtration, freezing, and distillation.
Why is water called a compound?
Compounds contain two or more different elements. Water is a molecule because it contains molecular bonds. Water is also a compound because it is made from more than one kind of element (oxygen and hydrogen). It is not a compound because it is made from atoms of only one element - oxygen.
Is sugar a mixture?
A compound is what table sugar is. Sucrose is made of three elements: carbon, hydrogen, and oxygen. Each "element" can be identified and separated from the other through physical means. Sugar can be mixed into all kinds of things to create a mixture or a solution, but the sugar itself is a compound.
Is soil a mixture?
soils is a heterogeneous mixture of sand, clay, organic substances like dead plant material and water. Soil is not a pure substance but a mixture. This mixture is quite complex in its composition.
Why water is a mixture?
A mixture is when two or more substances combine physically together. However, in water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone. Therefore, water is not a mixture; it is a compound and it is pure.
Why air is a mixture and water is a compound?
Water is a compound because it is composed of water molecules, each one with 2 H atoms & 1 O atom. Air is a mixture because it is in fact composed of mostly O-gas molecules (each with 2 O atoms) and N-gas molecules (each composed of 2 N atoms).
