  12. Pb(OH)2

  13. Do an atom inventory for this equation.2N2 + 5 O2 2 N2O5

  14. Atoms: Reactants Products 4-N 4-N 10-O 10-O

  15. Name: Ca(NO3) 2

  16. Calcium nitrate

  17. Do an molecule inventory for this equation.2N2 + 5 O2 2 N2O5

  18. Molecules:two-N2five-O2two-N2O5

  19. Name: (NH4)2CO3

  20. Ammonium carbonate

  21. Give an example of an anion.

  22. -SO4-2, Cl-1, O-2, etc.

  23. Define what a product is.

  24. -material on the right side of the equation-it’s what is being “made” in the reaction

  25. Why was distilled water used as a control in the Water Testing lab?

  26. -it was known not to contain any ions.-so we could compare the tap water results to a negative test.

  27. How many hydrogen molecules are on the reactant side of this equation?N2 + 3 H2 2 NH3

  28. Three hydrogen molecules;3-H2

  32. Al(HCO3 )3

  33. Name: HgCl2

  34. Mercury (II) chloride(Hg+2 Cl-)

  35. Name these elements and list how many of each there are. NaHCO3

  36. Na-sodium-1H-hydrogen-1C-carbon-1O-oxygen-3

  37. Give an example of a cation.

  38. Fe+3, Na+1, Ca+2, etc.

  39. Define what a reactant is.

  40. -it is the material on the left side of an equation.-it’s the material you start with.

  41. Define ion.

  42. -a particle that has gained or lost an electron.

  46. -chlorine, Cl-1-sulfate, SO4-2

  47. List what we know so far in the Riverwood fish kill.

  48. -water has been shut off-no microorganisms have been identified-no toxins detected-all kinds of fish found dead below the dam in the river
