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 SUBSTANCES Heterogeneous mixtures Homogeneous 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: NaCl (salt) CO2 H2O

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.
