General Chemistry Spring 2009

In this segment I Worked out all of the problems on the Exam #2 for the Fall 2006 semester. This will be an excellent review for the final.

In this segment I Worked out all of the problems on the Exam #2 for the Spring 2006 semester. This will be an excellent review for the final.

In this segment I did a number of problems from a past Exam #2. I began by doing a problem where the products of several reactions had to be predicted. The second problem the ionic and net ionic equation was written for two of the reactions discussed in the first problem. Next we did one of my favorite problems converting from grams to mol using molar mass and finding the number of molecules or formula units using Avogadro's Number. Then we looked at a challenging combustion analysis problem for determining empirical formulas. An interesting problem that combined stoichiometry and concentration. The last problem was a limiting reagent problem.

In this segment I review each of the questions on the CHEM 1314 Exam #1. I do the problem and discuss some of the point assignments and some of the places where students went astray.

In this segment I do go over how to answer PS10.2, PS10.6 - PS10.9. Review this problem set podcast in preparation for Exam #3 there are many good problem solving examples.

In this segment I do go over how to answer PS6.1 - PS6.7. Review this problem set podcast in preparation for Exam #2 there are many good problem solving examples.

In this segment I do go over how to answer PS3.10a and PS3.10b. These are both good, challenging problems that you will want to review to be sure you understand. Checkout Sample Exercise 3.15 on Page 99, and Execises 3.51 - 3.54 at the end of the chapter.

This segment covers questions asked by students about PS#13 and PS#14 on Thursday, December 7, 2006. THe questions asked on PS#13 were problems 4, 5, 6 and 7. On PS#14 problems 2, 3 and 5 were asked. A question on the Boltzman distribution (range of speeds of particles in a sampe of gas) was also asked.

In this clip I go over how to access some of the resources you will need to run animations on the CHEM 1515 web site. I discuss and demonstrate how to access the Java RunTime Environment that you will need to run any of the animations created by Kirk Haines, Dr. Abraham and myself that are included in the DCI and Computer Lab Activities Workbook. I also demonstrate how to access the Molecular Workbench animations.
