Pure Substances
Matter that has a uniform and unchanging composition is a substance.
A substance is made of the same things in the same proportions every time.
All samples match: Water Lead Salt

Two types of substance
Elements Made of only one type
of atom Cannot be broken
down (physically or chemically) into simpler substances
Used to make all other matter
All listed on the periodic table
Compounds A combination of two
or more different elements that are combined chemically
The compound has different properties than the elements that make it up
Can be separated, but only by chemical reactions

Mixtures
Mixtures are combinations of two or more pure substances that can be physically separated.
Mixtures vary in composition: Not everyone has the same chicken soup

Two types of mixture
Heterogeneous These are not blended
smoothly throughout Two samples of the
mixture don’t match
Ex: Raisin Bran River water Pulpy orange juice
Homogeneous These have a constant
composition throughout.
Always a single phase (i.e. two liquids mixed)
Often called solutions
Ex: Salt water Air Steel (Iron and
carbon)

Fill out the “matter web”
Start with “Matter” in the top box.
What are the two types of matter that we talked about today?
Each type of matter has two categories. What are they?
