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

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.

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.

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?

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?

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 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?

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?

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?

Complete the Table- Formula and Name the following compounds Na +1 Ca +2 Al +3 Fe +2 Fe +3 NH 4 +1 Cl -1 O -2 N -3 OH -1 NO 3 -1 SO 4 -2 PO 4 -3
