1. Classifications of Matter

2. Matter
Has mass
Takes up space
ex….
Chemistry is the study of MATTER!

3. Physical means:
a. Sorting
b. Filtering
c. Heating and cooling
Each component keeps the same characteristics after separation

4. Mixtures Contain more than one kind of matter
Can be separated physically

5. Types of Mixtures
Homogeneous mixtures – are the same throughout; every sample has the same ratio of ingredients
Ex: Chocolate Ice Cream
Heterogeneous Mixtures – vary throughout; each sample has the potential to have a different ratio from the next
Ex: Chicken noodle soup

6. Mixture Examples Petroleum (Crude Oil) – 1,000,000 molecular compounds
Milk – Fat, Whey, Liquids
Soda – Carbonated water, corn syrup, caramel color, phosphoric acid, natural flavors and caffeine
Paint – Pigment, Latex, thinning agents

7. Substances Cannot be separated by physical means
May contain more than one kind of matter but can only be separated by chemical means

8. Types of Substances
Elements – Contain only one kind of matter; specifically one kind of atom
Compounds – contain two or more elements and cannot be separated without chemical means

9. Review Questions: Types of matter
What are the four main classifications of matter?
Give two examples of each type of matter
What are three ways to separate a mixture by physical means?
What kind of substance is Iron?
