Heterogeneous Mixtures

Type of matter consisting of at least two parts physically combined Visible parts Varying composition Impure Physically separable

Heterogeneous Mixture Examples

Dirt Heterogeneous mixtures have more than one visible part

Concrete Car

Homogeneous Mixtures

Matter that is uniform throughoutReferred to as a Solution 1 visible part

(uniform distribution)

Constant composition

Even distribution of particles

Solution (Homogeneous Mixture) Examples

Salt water Brass

Glass Solutions appear to be one part, but are actually just mixed very well
