Classification of matter and Mixtures Guided Notes on PAGE 19

Objectives SWBAT classify a mixture as a suspension, colloid or solution. SWBAT identify the properties of homogeneous and heterogeneous mixtures.

Classifying Matter Concept Map Today we will be using a CONCEPT MAP in class to organize our information that you will see during the lesson.

A mixture is a combination of two or more substances where there is no chemical combination or reaction.

Mixtures combine physically in no specific proportions. They just mix. Did you know… Mixtures combine physically in no specific proportions. They just mix.

Classification of Mixtures Mixtures can be heterogeneous or homogeneous.

What happens when Mixtures are created? When you create a mixture, there are no new substances formed. Each part of a mixture keeps its own properties.

Matter Pure Substances Compounds Elements Mixtures Heterogenous Suspension Homogenous Colloid Solution

Matter Everything in the universe is made up of MATTER. Matter cannot not be created or destroyed by any chemical or physical process

Pure Substances Compounds Elements Chemical combination of two or more atoms Made up of atoms, cannot be further separated by physical or chemical means

Mixtures Heterogeneous Homogeneous Mixture where the substances are not evenly distributed. They usually involve a mixture of a solid in a solid. Mixture where the materials are evenly distributed. Usually involve a mixture of two or more liquids, gases or a solid that dissolves in a liquid

Suspension A type of HETEROGENOUS mixture This type of mixture will create different layers Example:

Colloids A type of HOMOGENOUS mixture This type of mixture has particles within it that WILL scatter light. Example:

Solution A type of HOMOGENOUS mixture Particles, atoms, ions, or compounds that WILL NOT scatter light. Solution have 2 parts a solvent and a solute. Example:
