  1. 1. - Combining substances so that new substances are formed that are not separated by normal chemical means. The new substances have properties different from those of the original substances.
  2. 3. - Temperature at which a solid substance becomes a liquid.
  3. 4. - The amount of matter in a defined volume. (density = mass/volume)
  4. 7. - A chemical substance that produces hydrogen ions in solution and tastes sour.
  5. 9. - The readiness of a substance to produce hydroxide ions.
  6. 10. - Property of a substance relating to how easily it reacts with other substances.
  7. 12. - A characteristic of a substance that describes its potential to change when interacting with other substances (reactivity with air or water, combustibility, flammability).
  8. 16. The ability to produce electricity
  9. 18. The characteristic of being able to attract because of an electrical force
  10. 20. - A type of change in which the form of matter is altered but one substance is not transformed into another.
  11. 21. The characteristic of a slow moving sticky substance
  12. 22. - Measure of the amount of matter in an object.
  13. 26. - A chemical substance that produces hydroxide ions in solution and tastes bitter.
  14. 27. - The characteristic smell of a substance.
