Upcoming tests

[Note:  This announcement post will stay at the top of the page for a while.  To see the latest content on the site, just scroll down a bit.]

Upcoming tests in Mr. Taylor’s chemistry courses.

CHM 100:  The second CHM 100 test will be on Wednesday, 10/13/2010. This test will cover chapters 4 and 5.  (We’ll be done with chapter 6 before then, but chapter 6 will be covered on the third test.

CHM 110 01 and 02:  Your second CHM 110 test will be on Wednesday, 10/13/2010.  This test will cover chapters 3 and 4, as well as the material on chemical equations from chapter 2.  A periodic table, chart of polyatomic ions, and solubility chart will be provided.  Bring your calculator!

CHM 110 03:  Your second CHM 110 test will be on Thursday, 10/14/2010.  This test will cover chapters 3 and 4, as well as the material on chemical equations from chapter 2.  A periodic table, chart of polyatomic ions, and solubility chart will be provided.  Bring your calculator!

CHM 110: Shared data for Experiment 3B (Thursday lab, section 3)

Here’s the shared data from CHM 110 Experiment 3B. These are the ratios of mass product / mass barium chloride dihydrate that you need to complete the table on page 74 and answer the questions on pages 75 and 76.  This is data for the Thursday lab section (section 3)!

Ratio of (mass product / mass BaCl2.2H2O):

  • 0.85299
  • 0.85181
  • 0.80819
  • 0.85341

The write-up for Experiment 3B is due at our next lab meeting. If you have any questions about either the calculations or the rest of the write-up, either come by my office or ask here in comments.

Here’s a handout that describes the calculation procedure for this experiment:

I recommend that you use your TI-83 calculator or a spreadsheet to find the standard deviation the lab manual asks you to calculate.
