2. Our properties make us what we are  Some of Malfoy’s properties include  Ice Blue Eyes  Short, White-Blonde Hair  Sneering Smile  Desire for power  Famiy riches  Dislike of Muggles

3. A. Things that can be measured with the metric system  length  weight or mass  density  boiling point  freezing point

4.  Mercury (a liquid) is more dense than lead. May be we should say “Get the MERCURY out”, not “Get the lead out.”  Solid water is less dense than liquid water. That’s why ice cubes float in water.  Weight is actually measured in Newtons, not grams.

5. B. Inertia – matter at rest will stay at rest matter in motion will stay in motion

6. C. Things that can be determined with the senses  Color  Texture  Hardness  Luster (shiny-ness)  Taste  Shape  Odor

7.  Sulfur can be identified by its “rotten egg” smell.  Diamond is the hardest mineral we know of.  Halite tastes like salt.

8. D. Describe the phase of matter of the substance  solid  semi-solid (amorphous)  liquid  gas  plasma

9. A. Describe the way matter interacts  These interactions are sometimes called chemical reactions

10.  In actual chemistry classes, you’ll learn how the electrons of individual atoms of matter combine or transfer to make new compounds.  (aren’t you glad we don’t have to learn that yet?)

11. B. Oxidation Reactions  Oxygen and iron react to form iron oxide (rust)  Oxygen and hydrogen react to form water  Oxygen and copper react to form copper oxide

12. C. Acid-Base Reactions  Zinc fizzes in hydrochloric acid  Hydrochloric acid bubbles and fumes on limestone  Vinegar bubbles and foams when in contact with baking soda

13. D. Electrical Reactions  When electricity is passed through water and acid, hydrogen and oxygen gasses are released  When electricity is passed though an acid solution with a metal object inside, and a copper diode, the metal becomes “plated” with copper

14.  Sodium + chlorine = salt  Silver + sulfur = silver sulfide (tarnish)

19. 6- If heat energy is added to solid aluminum, what happens to the movement and spacing of the particles of aluminum? a. The particles move apart and slow down. b. The particles move apart and speed up. c. The particles move closer together and slow down. d. The particles move closer together and speed up.
