No.
To start with, air is not a pure substance,
and mixiong it with something else just makes it worse.
Chemically pure water is simply dihydrogen oxide or hydronium hydroxide. Distilled pure water is chemically pure water plus some gases (oxygen, nitrogen and carbon dioxide) from contact with the air and possibly some light organics with B.P. s around 100oC De ionized pure water is chemically pure water with non-polar compounds and potentially some gases and microorganisms plus some gases (oxygen, nitrogen and carbon dioxide) from contact with the air Filtered pure water is chemically pure water with no organic or inorganic particles but any dissolved materials and salts plus some gases (oxygen, nitrogen and carbon dioxide) from contact with the air Carbon filtered water is chemically pure water and no particulate or organic components and no dissolved metals plus some gases (oxygen, nitrogen and carbon dioxide) from contact with the air.
Liquid air is a mixture not a compound. As we know that air is a mixture of different gases. It contains 78% nitrogen and 21% oxygen and remaining 1% is comprising various other gases. The process of preparing liquid air does not involve any chemical reaction and hence no compound is formed. It is basically a physical process involving compression of air as well as cooling simultaneously. Thus liquid air remains a mixture.
No, it is composed of nitrogen, oxygen, water vapor, carbon dioxide and other gasses.
Sodium and iron are pure elements, while sugar and oxygen are pure compounds. Air, on the other hand, is a mixture of gases and not a pure compound.
When a substance changes from a liquid to a gas, it is called vaporization or evaporation. This process occurs when the substance absorbs enough energy to overcome the forces holding its molecules together in the liquid phase.
No. Air is not pure substance. Air has all dust and dangerous gases with it. From place to place its composition changes.
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.
Air is a mixture.
Air is considered a pure substance because it is a homogeneous mixture of gases, mainly nitrogen, oxygen, carbon dioxide, and trace amounts of other gases. Each component of air retains its unique chemical properties and cannot be separated by physical means without changing the composition of air.
Air is a mixture.
Air is a mixture of gasses, about 78% nitrogen, 21% oxygen and then a dash of others. Nitrogen OTOH is one of the elements out of the periodic table, which I guess is what you mean with a pure substance.

Natural air is always a mixture, and more or less homogenous in its major constituents. However, if the balloon was inflated by mouth, it will have less oxygen and more carbon dioxide than the air outside the balloon, which is also a mixture.
CO2 is a pure substance and so is homogeneous. Hint: if it has a chemical formula then it is a pure substance.
A substance that takes up a significant amount of water from the air to form a liquid solution is known as a hygroscopic substance. These substances have the ability to absorb moisture from the air through a process called hygroscopy, resulting in the formation of a liquid solution. Examples of hygroscopic substances include certain salts such as calcium chloride and silica gel.
Pure air consists of a mixture of gases like nitrogen, oxygen, carbon dioxide, and others, so it is not considered a pure substance. However, if the air is free from pollutants like chemicals or particulate matter, it would be considered clean and unpolluted.
It depends. You can have a gaseous mixture such as air, which would be a homogeneous mixture. But a single gas such as oxygen or methane would be a pure substance.
