molecules compounds mixtures

A mixture is a material containing two or more elements or compounds that are in close contact and are mixed in any proportion. The components of a mixture can be separated by physical means. For example, air, gun powder, et..

Mixtures - A mixture is a combination of two or more elements or compounds in any proportion so that the components do not lose their identity. Air is an example of a mixture (several gases mix to form air). Mixtures are of two types, homogeneous an..
