Final answer:
A mixture where the composition isn't uniform throughout is called a heterogeneous mixture. Heterogeneous mixtures include suspensions, colloids, and emulsions.
Step-by-step explanation:
A mixture where the composition isn't uniform throughout is called a heterogeneous mixture. Heterogeneous mixtures are composed of different substances that are not uniformly mixed and can be visually differentiated. Examples of heterogeneous mixtures include suspensions, colloids, and emulsions.
Suspensions are mixtures in which solid particles are dispersed in a liquid or gas medium. The particles in a suspension are larger and will settle out when left undisturbed. Examples of suspensions include muddy water or sand in water.
A colloid is a mixture in which small solid particles or liquid droplets are dispersed in a liquid or gas medium. The particles in a colloid are larger than those in a solution but smaller than those in a suspension. Examples of colloids include milk, fog, and mayo.
An emulsion is a special type of colloid in which two immiscible liquids are combined, such as oil and water. Emulsions are created by adding an emulsifying agent to help stabilize the mixture.
