Information of the week! June 8, final exam week!
You have been a great group to work with. I will see many of you in the summer, but just wanted you to know that you are very good students.
If anyone wants to get a head start on Chem 133 for next quarter, we will start with Ch. 6, Thermochemistry, and I have updated the 133 homework page and the notes are up..
1669 Chem 133 evening section during summer is in the online schedule. It meets 5:45-8pm T, Th in Sci 123.
Anwers to the sample final exam- 1c, 2j, 3b, 4e, 5d, 6b, 7e, 8d, 9a, 10d, 11e common ion, 12a, 13b, 14c, 15e, 16d, 17 both b and c, 18 c, 19d, 21a, 22a, 23b, 24b, 25b, 26b, 27a, 28a, 29b, 30b, 31a..........39d, 40b, 41b, 42b, 43a Sorry, here are the rest. 44.b, 45e, 46b, 47e, 48d, 49b, 50 d, 51 b
There is one wrong answer, #1?. Gives ionic as the answer to a set of properties but it should be network cov.
| 32. find moles ethanol and moles methanol Xmethanol = 0.489 | 36 top of hills are act. complex and intermediates is the in between. lower left=reactants, lower right =products; Ea values are from the reactant or product to the top of the hill. |
| 33. CaTiO3 | 37. rate= k[NO]2[H2], and average K is about 280, depending on whether you use one value or an average. |
| 34. calc Q and compare to K. Q=8.15=K therefore at equilibrium. | 38. t = 0.575°C, m = 0.1135 and you get 0.01135 moles, 2.500g/0.01135 mole= 220 g/mol to 3 sig. figs. |

Answers to the Chem 132 Sample Exam III- 1a, 2b, 3a, 4a, 5a, 6b, 7e, 8c, 9c, 10a, 11e, 12c, 13d, 14d, 15a, 16d, 17a, 18 first order, ln[ ] vs t is a straight line (do the graphs on graph paper), 19 a. [A]t= 0.18 mol/L, b. 58sec, 20 look up the answers, 21c, 22. 1x10-2, 23 a. pH = 2.74, b. pH=11.7, 24 c, 25. all, acid plus the conjugate base in each. 26a. H2S b. H3PO4 c. H2SO4
