  1. 2. properties that can only be observed or measured by changing the chemical identity of a substance
  2. 4. process by which the atoms of one or more substances are rearranged to form different substances
  3. 5. properties that can be observed directly or measured without changing the chemical identity of the substance
  4. 7. how easily a substance reacts, usually with an acid or base
  5. 13. two or more substances physically combined (variable composition)
  6. 15. temperature at which a solid becomes a liquid
  7. 16. how easily a substance will set on fire
  8. 18. how easily a substance reacts with oxygen
  9. 21. simplest form of matter from which more complex substances are made
  10. 22. substances in the mixture are not evenly spread out
  11. 23. the result
  12. 24. anything that takes up space and has mass
Down
  1. 1. Matter is neither created or destroyed during a chemical change. It only changes forms.
  2. 3. a change in a substance that only affects its physical properties
  3. 6. a fluid’s resistance to flow
  4. 8. a measure of how well a solute dissolves in a solvent
  5. 9. components are evenly distributed out on a microscopic level
  6. 10. two or more elements chemically combined in a fixed proportion
  7. 11. a change in a substance that affects its chemical properties thus a chemical reaction occurs and a new substance is formed
  8. 12. all particles in matter are identical (fixed composition)
  9. 14. temperature at which a liquid becomes a gas
  10. 17. what is doing the dissolving
  11. 19. what is being dissolved
  12. 20. measure of compactness or consistency of a material
