Matter Pure Substances Elements Compounds Mixtures Homogeneous Heterogeneous

Matter is Anything that has Mass or Volume … Mass- amount of matter in an object Volume- Amount of space an object takes up

All Matter Can Be Classified As… Elements Compounds Mixtures

All Matter Can Be Classified As… Elements- simplest form of a pure substance Cannot be physically or chemically broken down Compounds- pure substances that are made up of 2 or more elements Can be chemically broken down

What are pure substances? Contain a fixed composition For Example: composed of only 1 element or 1 compound Always considered homogeneous.

All Matter Can Be Classified As… Mixtures- two or more substances that ARE NOT chemically combined. Can be physically separated Retain individual properties

Two Types of Mixtures Heterogeneous Mixtures- 2 or more physically combined substances (elements/compounds) Substances are not evenly distributed; thus, it is not considered uniformed.

Two Types of Mixtures Homogeneous Mixtures- Substances are evenly distributed; thus, it is considered uniformed. Solutions– is a special example of a mixture where one substance dissolves into another.
