Note Guide: Classification of Matter

Use this note guide to collect and organize the information from the power point presentation.

Every sample of matter can be classified as a ______or a ______.

Pure Substance
Element / Molecule / Compound
Description
Examples
Comments


Consider Table Salt:

Element + Element = Product
Name
Symbol
State of Matter

Sometimes when two elements bind together chemically – the product doesn’t look the same as the original elements.

The Law of Definite Composition states:

Use the table to draw each of the following compounds. Describe the fixed ration of the composition of each compound.

Carbon Monoxide / Carbon Dioxide
Chemical Formula:
____ C: ____ O / Chemical Formula:
____ C: ____ O


Define:

·  Molecule:

·  Diatomic Molecule:

Examples / Formula / Drawing / Type / Fixed Ratio
Oxygen
Hydrogen
Nitrogen oxide
Water
Nitrogen dioxide


Compound – Molecule connections. Some compounds are molecules, some are not. Use the table below to identify each as a compound and/or molecule by using a check mark. Use the last column to describe why you choose each.

Molecule / Compound / Explanation
Water
Ozone
Table salt

Define the prefixes:

·  HOMO –

·  HETERO –

Mixtures come in two types.
Use the table below to describe the two types of Mixtures

Homogeneous / Heterogeneous
Solution / Non – solution / Colloid / Suspension
