Classifying Matter Notes

Matter • Anything that has mass and takes up space. • There are many different kinds of mater that have different characteristics such as boiling and melting temperatures, hardness, and elasticity.

MATTER MIXTURES Homogeneous mixtures Heterogeneous mixtures SUBSTANCES Elements Compounds

Mixtures • Mixtures contain more than one kind of matter. Mixtures are not chemically combined. • There are 2 types: Homogeneous and Heterogeneous mixtures

Separating Mixtures • Mixtures can be separated be physical means such as: – sorting – filtering – heating – cooling

Homogeneous Mixture A homogeneous mixture contains more than one type of matter and is the same throughout. Other Examples of Homogeneous Mixtures?

Heterogeneous Mixture • A mixture that contains more than one type of matter and is not the same throughout An example of a heterogeneous mixture is chicken noodle soup

Substances • Matter that has a specific composition and specific properties. • There are 2 types of substances: Elements and Compounds

Elements • A substance that contains only one type of atom. Iron Bolts Hydrogen Gas

Compounds • A substance that contains more than one type of atom. • Examples: Na. Cl (salt) CO 2 H 2 O

Main difference between Mixtures and Substances? • Substances cannot be separated into different kinds of matter by physical means such as filtering, sorting, heating, or cooling. • Mixtures can be separated by physical means.
