An air sample consists of oxygen and nitrogen gas as major components. it also contains carbon dioxide and traces of some rare gases. all these gases are evenly distributed throughout the sample of air. which term or terms could be used to describe this sample of air? check all that apply. view available hint(s)
- solution,
- pure chemical substance,
- heterogenous mixture,
- mixture,
- compound,
- homogeneous mixture,
- element.

Explanation:

A mixture is defined as the substance that contains two or more different number of substances that are physically mixed together.

For example, a mixture of air which contains oxygen, nitrogen and other gases.

A mixture in which solute particles are unevenly distributed into the solvent then it is known as a heterogeneous mixture.

For example, sand in water is a heterogeneous mixture.

A homogeneous mixture is defined as the mixture in which solute particles are evenly distributed in a solvent.

A homogeneous mixture is a clear solution.

For example, salt dissolved in water is a homogeneous mixture.

A solution is defined as the substance in which two or more substances are mixed together.

A compound is defined as the substance that contains two or more different elements that chemically combined together in a fixed ratio by mass.

A element is defined as the substance that contains only one type of atoms.

For example, a piece of sodium element will contain only atoms of sodium.

Whereas a pure substance is defined as the substance which contains only one type of molecule or one type of atom.

For example, , etc are pure substances.

Thus, we can conclude that the terms which could be used to describe the given sample of air is as follows.
