  8. How do you prove a chemical reaction has occurred?

  9. Lab analysis

  10. Name 5 observations that suggest a chemical reaction has occurred

  11. Change in color, odor, formation of a precipitate, release of energy, gas, light

  12. This type of reaction involves one reactant.

  13. What is decomposition?

  14. This type of reaction involves one product.

  15. What is synthesis?

  16. Which of the following • compounds does not • conduct electricity? • a) AlBr3 • C6H6O6 • CaCO3 • FeBr2

  17. b) Its covalent

  18. How many molecules of oxygen are in this reaction? 4Al + 3O2 --> 2Al2O3

  19. 3

  20. What fundamental law is demonstrated in balancing equations?

  21. The Law of Conservation of Mass

  22. Balance this equation: ZnS + O2 yields ZnO + SO2

  23. 2:3:2:2

  24. How many atoms are present in Sr3(PO4)2?

  25. 13

  26. Why can't you change the subscript when balancing equations?

  27. It changes the identity of the substance

  28. Name 4 elements that will replace strontium in a single replacement reaction.

  29. Li, Na, K, Rb, Ba

  30. What must appear for a double replacement reaction to occur?

  31. A precipitate, gas, or water

  32. Will this reaction occur? FeS(aq) + Ni(s) ---> Explain your answer.

  33. No, nickel is lower on the activity series than iron.

  34. In an experiment between aluminum bromide and copper sulfate, a blue liquid is formed. Explain how this is not a double replacement reaction.

  35. What is because no precipatate is formed, all products are still dissolved

  36. Which is more reactive? sodium or copper

  37. What is sodium?

  38. Which type of reaction produces two pure elements?

  39. Decomposition

  40. This type of reaction requires use of a reactive element to break up a compound.

  41. Single replacement

  42. The symbol for a solid dissolved in water.

  43. (aq)

  44. What reaction always produces H2O and CO2?

  45. Combustion

  46. Name the product for calcium combined with hydrochloric acid

  47. What is hydrogen and calcium chloride?

  48. What is the state of a pure ionic compound at room temperature?

  49. Solid
