1. Pure Substances, Mixtures and Solutions, Oh My!
Pg. 33

2. All Matter Can Be Classified As…
Elements
Compounds
Mixtures

3. 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

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

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

6. 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.

7. 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.
