Congratulations!  You’ve all made it to the end of the second week.  I hope you enjoyed the Labor Day holiday!

CHM 101

We discussed matter this past week, and are currently discussing energy.  Energy is covered in the textbook in sections 10.1-10.5, so make sure to take a look at those sections in the textbook.  After we finish with sections 10.1-10.5, we’ll return to where we left off in the textbook and continue on with chapter 4.

Remember – we have a test a week from Wednesday, and our first experiment in lab this week!

CHM 110 (01 and 02 – Monday/Wednesday sections)

We’ve finished up our discussion of math – significant figures and dimensional analysis.  I’ve posted the practice problems we worked on in the lab periods this week.  Take a look at these for extra practice on dimensional analysis if you need it – there are more problems there than we actually worked in the lab period.  For the rest of the week, we’ll work on Chapter 2 – properties of the atom, the periodic table, and chemical conpounds.  The first test is coming up a week from Wednesday, so make sure you stay current with the material.  For sections 1 and 2, the first test will likely cover up through nomenclature of ionic compounds.

Remember that CHM 110 labs aren’t meeting during week 3 – we’ll only have lecture meetings.

CHM 110 (03 – Tuesday/Thursday sections)

We have, like the other sections, finished up the math – significant figures and dimensional analysis.  I’ve posted a 36-problem practice set on the main page which you can use for more practice on dimensional analysis if you feel you need it.

Keep reading in Chapter 2 – we’ve already covered the atom and Dalton’s atomic theory – since the test we’ll have a week from Thursday will cover the first two chapters in the textbook.

Remember that CHM 110 labs aren’t meeting during week 3 – we’ll only have lecture meetings.

If you have any comments or questions, please leave them as comments on this post.

Here’s a set of dimensional analysis practice problems and their answers.  Those of you in the Monday and Wednesday labs will recognize this as the exercise we did during the lab period, but it contains more practice problems than we actually worked in the exercise.  Take a look!
