2 MixturesTwo or more substances that are not chemically combined with each other and can be separated by physical means.The substances in a mixture retain their individual propertiesExamples: Fruit Salad, Pizza…any others?
3 SolutionsSolution: is a special kind of mixture where one substance dissolves in another.It may appear to be a single substance but it is composed to two or more substances that are distributed evenly amongst each other.A solution may be a liquid, a gas or a solid.Examples: Chocolate Milk, Powdered Lemonade and Water, Steel, Brass
4 ElementsThe simplest form of a pure substance. They cannot be broken into anything else by physical or chemical means.Examples: Gold, aluminum, leadElement Song
5 CompoundsPure substances that are the unions of two or more elements. They can be broken into simpler substances by chemical means.Examples: Table Salt
6 Two different types of mixtures: heterogeneous and homogenous
7 Heterogeneous Do not appear to be the same throughout the mixture. The different components are visibly distinguishable from one another.Example: Chocolate Chip Cookies, Pizza, Fruit Salad.
8 Heterogeneous Mixtures SuspensionA mixture that looks uniform when stirred or shaken that separates into different layers when it is not longer agitated.Example: Settled orange juice, medicinesColloidsis a mixture of very tiny particles of pure substances that are dispersed in another substance but do not settle out of the substance.Particles in colloids are much smaller than those in suspensionBecause of how small they are, they do not settle to the bottom to form a different layer.Examples: paint, whipped cream, fog
9 Heterogeneous Mixtures Emulsionis any mixture of immiscible liquids in which the liquids are spread throughout one anotherMayonnaiseLiquid-Liquid MixturesOil and vinegarThe two liquids are immiscible
10 Homogeneous MixturesHas the same uniform appearance and composition throughout.It is “well mixed”Example: Table salt and waterSolutions are homogenous mixturesIt is formed when one substance dissolves in anotherIt always has a substance that is dissolved and a substance that does the dissolving.Solute: the substance that is being dissolvedSolvent: the substance that does the dissolvingExamples: vinegar, air, ocean water
11 Homogenous Mixtures Solutions are homogenous mixtures It is formed when one substance dissolves in anotherIt always has a substance that is dissolved and a substance that does the dissolving.Solute: the substance that is being dissolvedSolvent: the substance that does the dissolvingExamples: vinegar, air, ocean water
