40 FACTS ABOUT MIXTURES BY: PJ MIANA _________________________________________________ The following are the facts about mixtures:  A homogeneous mixture is a mixture in which the components are evenly distributed throughout the mixture. They are also called solutions. A heterogeneous mixture is a mixture in which the components are not evenly distributed throughout the mixture. They are also called suspensions. Homogeneous mixtures can be either solid , liquid , or gas. Heterogeneous mixtures can also be either solid, liquid, or gas. Examples of homogeneous mixtures include air, salt water, vinegar, liquid solutions, gas solutions, and solid solutions. Examples of heterogeneous mixtures include salad, chocolate chip cookies, sand, colloids, suspensions, and emulsions. Homogeneous mixtures have a uniform appearance throughout. Heterogeneous mixtures have a non-uniform appearance throughout. Homogeneous mixtures cannot be separated by physical means, but it may be difficult o
