1. Sodium metal is added to water. (single replacement)
2. Dilute sulfuric acid is added to a solution of lithium hydrogen carbonate. (acid + carbonate)
4. Excess concentrated potassium hydroxide solution is added to a precipitate of zinc hydroxide. (complex ion)
5. The gasses boron trifluoride and ammonia are mixed. (synthesis) (NOTE: Boron has only 6 e-)
6. A solution of tin(II) chloride is added to a solution of iron(III) sulfate. (double displacement)
8. An acidified solution of potassium permanganate is added to a solution of sodium sulfate. (redox)
In preparation for Monday's quiz, I (Evan... not Mrs. McCluskey) will post the actual equations as I figure them out or someone sends them to me...Do you have a correct equation? are one/all of them wrong?...please e-mail me!

1. Na (s) + H2O (l) ---> Na+1OH-1(aq) + H2 (g)
2. H+1 (aq) + HCO3-1 (aq) ---> H2O (l) + CO2 (g)
4. OH-1 (aq) + Zn+2(OH)2-1 (s) ---> Zn(OH)4+2 (aq)
5. BF3 (g) + NH3 (l) ---> BF3NH3 (g)
6. Sn+2 (aq) + SO4-2 (aq) ---> Sn+2SO4-2 (s)
8. MnO4-1 (aq) + SO3-2 (aq) --> Mn+2 (aq) + SO4-2 (aq) + H2O (l)
