and compounds.
2 forms of pure substance - ANS Element: a substance that cannot be decomposed to simpler
substances. EX: anything on the periodic table of elements.

broken down)
Mixture - ANS Exhibit the properties of the substances that make them up. 2 types:
Heterogenous and Homogenous.
2 types of mixtures - ANS homogeneous: also known as solution, their compositions do not
vary throughout a sample. EX: coffee, or smoothie, you can't see the milk and coffee and sugar
separated.
heterogeneous: their compositions vary throughout a sample. EX: Pizza, you can pick the
pepperoni from the cheese or sauce, another example would be granite countertop because
