  5. Phases of Matter. • Solid • Liquid • Gas

  6. What are the two physical methods that matter occurs in? • Mixtures and Pure Substances! • Name the two types of pure substances. • Elements and Compounds • Name the two types of mixtures. • Homogenous and Heterogeneous

  8. Heterogeneous or Homogenous? • Fruit Salad • Lemonade • Sweet Tea • Vegetable Soup • Brass Lamp

  9. Substances that cannot be changed into simpler substances and are made of one kind of atom. • ELEMENT • Examples: Na (sodium) Cl (Chlorine), H (Hydrogen), O (Oxygen), C (Carbon), N (Nitrogen)

  10. What are pure substances that are composed of two or more types of elements that are chemically combined? • COMPOUNDS • Ex: CO2 , H2O, H2O2, NaCl,

  11. What is composed of two or more different substances that retain their own individual properties and are combined physically? • MIXTURES

  12. Element, Compound, or Mixture • Composed of one type of atom • Element • Can be separated by physical means • Mixture • Will be in the form of a molecule • Compound • Can be formed back into pure substances only by chemical means • Compound

  13. Element, Compound, or Mixture • May be heterogeneous or homogenous • Mixture • Is mixed together, but looks the same throughout the mixture • Mixture: homogeneous • Is mixed together, but looks different throughout the mixture • Mixture: heterogeneous

  14. Bonus Questions • Another name for Homogenous mixture • Solution • The substance being dissolved in a mixture • Solute • The substance that dissolves the other substance in a mixture • Solvent • 3 ways a mixture can be separated • Filter, sift, or evaporation
