  1. 6 Week Common Assessment Review If you have any hope of passing this exam,…. You Must Do This Review!!!!! ( Really, Do the Review!!!!)

  2. Properties of matter • What are the 5 phases of matter? • What is a physical change? Is there another term used to describe a physical change? • What is heterogeneous material? Give an example. What is homogeneous material? Give an example. What is a solution? What are the parts of a solution? • What is the difference between elements and compounds? • What is the difference between Intensive and Extensive Properties? Give examples.

  3. Properties of Matter • What is a chemical reaction? What is evidence of a chemical reaction? • What is the conservation of mass? • A pot of water is on the stove and is boiling. Bubbles are coming to the surface of the liquid. What’s in the bubbles? • A) heat bubbles. • B) air bubbles. • C) nothing, it is just a space between the water. • D) steam, water as a gas.

  4. Phases of Matter Identify the different phases of matter and what type of phase change is occurring? Is the temperature increasing during a phase change? Why or why not? What is happening to energy during a phase change?

  5. What is happening? Describe what is happening in the graduated cylinder? Balsa Wood has a density of 0.16 g/ml. Where will it fall?

  6. Density Practice • 1. What is the density of balsa wood if a piece 1.0 cm x 3.0 cm x 2.0 cm has a mass of 96 g? • 2. What is the density of iron if 100.0 g of the metal is added to 25.0 mL of water and the volume increases to 37.0 mL? • 3. What is the density of a rock if it weighs 25.0 g and displaces 5.0 mL of water?

  7. Mixtures • 1. Is it easier to separate milk from coffee or milk from a bowl of cereal? • 2. Which mixtures pass through a filter paper? • 3. Which leave material behind on the filter paper? • 4. Salt Water is a solution? Why is it considered a mixture and not a compound? • 5. Look back at your data table from the lab and determine the visual clue that will help distinguish solutions, suspensions, and colloids. • 6. What atmospheric difference allows you to see the light rays on some days and not on others?

  8. Nomenclature • What is a compound? • How are they formed? • What type of compounds are there? • How do elements form ions? • Why do elements form ions? • What is Brinclhof? Or the heavenly seven? Why does this occur?

  9. Complete the Table- Formula and Name the following compounds
