  1. 1. A subatomic particle with a positive electric charge.
  2. 6. Percentage of reactants changed to useful products.
  3. 7. the heat required to raise the temperature of a particular substance by one degree.
  4. 13. A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
  5. 14. The amount of space on a substance has to react.
  6. 15. A manufacturing process that runs all the time.
  7. 19. The idea that the rate of a chemical reaction depends on the frequency of successful collisions.
  8. 20. A reaction which takes in energy, usually in the form of heat. This is shown by a drop in temperature.
  9. 21. A reaction which gives out energy, usually in the form of heat. This is shown by a rise in temperature.

  7. 10. The smallest particle of a chemical element that can exist.
  8. 11. How quick or slow a reaction is progressing.
  9. 12. The force between two atoms that are chemically joined.
  10. 16. The different physical forms of an element. For example, carbon can appear as graphite, fullerenes, and diamond.
  11. 17. a technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.
  12. 18. A comparison between the actual yield of a reaction and the predicted yield, expressed a percentage.
