  1. 1. Which state of matter has a definite volume and a definite shape? • Solid • Liquid • Gas • plasma

  2. 2. What is combustibility? • The ability to react with acids • The ability to conduct heat • The ability to dissolve in water • The ability to burn

  3. 3. Which of the following is a chemical change? • Dissolving • Bending • Boiling • burning

  4. 4. In which change of state do particles move farther apart? • Gas to solid • Gas to liquid • Liquid to solid • Solid to liquid

  5. 5. The melting and boiling points of silver are respectively 960.8 degrees Celsius and 1950 degrees Celsius. What is its freezing point? • 0 degrees C • 100 degrees C • 960.8 degrees C • 1950 degrees C

  6. 6. Which substance has a definite shape and definite volume? • A crystal of table salt • A solution of saltwater • Water vapor • Iced tea

  7. 7. In which substance are molecules rigidly arranged? a.. The water in a freezer at -2 degrees C b. The water in a cup at 22 degrees C (room temperature) c. The water in a pot at -100 degrees C d. The water in a steam engine at 110 degrees C

  8. 8. Which describes a change from gas to liquid? • Boiling • Condensing • Freezing • Sublimating

  9. 9. What does the law of conservation of matter state? • The total mass of the reactants is greater than the total mass of the product. • The total mass of the reactants is less than the total mass of the products. • The total mass of the reactants equals the total mass of the products. • Matter can not change form.

  10. 10. During a chemical reaction, methane (CH4) and oxygen (O2) combine to produce carbon dioxide (CO2) and water (H2O). The balanced chemical equation identifies the reactants and products for this reaction along with some of their masses. What mass (in grams) of oxygen (O2) is required for this reaction to occur?CH4 + O2 2CO2 + H2O16g ? 44g 36g • 16 • 36 • 44 • 64
