Classifying Matter

1
Classifying Matter
-Matter is anything that has mass and takes up
space. -Basically, stuff. -The building block of
matter is the atom.
2
Compounds

• Ionic Bond
• Metal to nonmetal is always an ionic bond.
• Metals are to the left of the staircase line on
  the periodic table (except hydrogen).
• The metal will always be first in the formula or
  name of the compound.
• NaCl
• CuO
• Iron II chloride
• Potassium phosphate

• Covalent Bond
• Nonmetal to nonmetal bond.
• Tend to have numeric prefixes in the name.
• Carbon dioxide
• Water
• PCl3
• N2O4

3
Mixtures

• Homogeneous
• Look the same throughout.
• Solutions are ALWAYS homogeneous mixtures.
• Usually separated by distillation or
  chromatography.
• Metal alloys tend to be homogeneous mixtures.
• Examples
• Orange juice (no pulp)
• Koolaid
• Gold necklace

• Heterogeneous
• Look different throughout.
• See layers.
• Usually separated by filtration.
• Examples
• Oil vinegar dressing
• Salad
• Soil
• Rocky road ice cream

Classify..be specific

• 1. Sodium bicarbonate
• 2. Water
• 3. Soil
• 4. Solution of sugar water
• 5. Phosphorous trichloride
• 6. Carbon Dioxide
• 7. Rocky Road Ice Cream
• 8. Alcohol lol
• 9. Pure Air
• 10. Calcium Gluconate

Properties/Changes of Matter

• Physical
• A property that can be observed without changing
  the identity of a substance.
• Melting point, boiling point, etc.
• Solubility
• Luster, ductility, malleability.
• Color
• Density (mass/volume)
• A change that occurs without changing the
  chemical identity of the substance.
• Any phase change (boiling, freezing, etc.).
• Dissolving

• Chemical
• A property that can only be observed by changing
  the chemical identity of a substance.
• Flammability
• Ability to rust
• Ability to tarnish
• A change that occurs and changes the chemical
  identity of the substance.
• Combustion
• Rusting or Tarnishing
• Rotting or Souring
• Any chemical reaction
• Color change.
• The creation of a new substance in a reaction is
  always chemical.
