Study Notes
Classifying Matter
- Matter classification includes pure substances and mixtures based on composition.
Pure Substances
-
Compounds consist of two or more elements chemically bonded:
- Examples:
- Silicon Dioxide (Sand)
- Sodium Chloride (Salt)
- Water (H2O)
- Carbon Dioxide (CO2)
- Lithium Iodide
- Sugar
- Hydrogen Peroxide
- Examples:
-
Elements are pure substances that cannot be broken down:
- Examples:
- Gold
- Oxygen
- Silver
- Lead
- Calcium
- Potassium
- Carbon
- Hydrogen
- Helium
- Baking Soda
- Examples:
Mixtures
-
Heterogeneous mixtures have visibly different components:
- Examples:
- Soil
- Italian Salad Dressing
- Raisin Bran
- Apple Pie
- Chocolate Chip Cookies
- Tacos
- Caesar Salad
- Rocky Road Ice Cream
- Examples:
-
Homogeneous mixtures (solutions) have uniform composition:
- Examples:
- Soda
- Pure Air (most is polluted!)
- Salt Water
- Kool-Aid
- Sugar Water
- Gatorade
- Whole Milk
- Skim Milk
- Raisin Bran with Milk
- Ocean Water
- Examples:
