Chemistry

• The study of matter and the changes it undergoes
• Matter
• Physical material of the world
• Has mass
• Takes up space

Always Remember

• We study chemistry at the submicroscopic level in
  order to explain macroscopic events

Section 1.2

• Classifications of Matter

11
States of Matter

• 3 Forms
• Solid
• Liquid
• Gas

12
Three States of Matter
13
Pure Substance Element Compound

• An element cannot be decomposed into simpler
  substances
• A compound is a relatively stable combination of
  two or more chemically bonded elements in a
  specific ratio.
• Can be decomposed

14
Mixtures

• Mixtures consist of two or more substances
• Homogenous mixtures are uniform throughout.
• Air, sea water, and a nickel coin
• Heterogeneous mixtures vary in texture and
  appearance throughout the sample.
• Rocks, wood, polluted air, and muddy water

15

• Pure Substances
• Fixed elemental composition

• Mixtures
• Varying composition
