mixtures =) Complete: A mixture is composed of substances which are not chemically combined. Mixtures are pure as they are composed of different substances not combined. Mixtures do not have a composition as the composition can easily be Air is an example of a as it is composed of, gases which are not chemically combined. The cormposition of the air can depending on how much there is of the gases. For example, the air we breath in contains carbon dioxide compared to exhaled air.
