Chem 101 Lab
Week #4
Hopefully, the lab will be an hour shorter this week. Y'all have been putting in some hard work, and deserve a little break.
The "half-quiz" will cover only thermodynamic issues. As you move further and further into chemistry, consideration of energy transfer become ever increasingly important. Afterall, for all you biologically oriented students, isn't that what biochemistry is all about - extracting chemical energy from food molecules?
The practice problems for lab, below, will be worked out in lab along with your own catalase kinetics data you obtained in the last lab session. Just print out those practice problems, and have them with you on Monday or Tuesday.
Also have with you the printout of the Magnesium oxide protocol so that you can do it in lab.
Laboratory Safety Notes (New items are in PURPLE).
Lab #4: Magnesium Oxide and the Law of Constant Composition
Catalase Kinetics - continued (the paperwork)
Learning about bi-linear and semi-log graph papers
Practice Problems for the Catalase Lab (#3)
The quiz will NOT deal with the Magnesium Oxide lab work,
but will deal only with the general aspects of thermodynamics we talked about in class, and also how those laws apply to the catalase reaction.
