No more mr. niceguy...when it comes to Problem Sets. If your problem set is not turned in at the beginning of class it will NOT be accepted. No ifs, ands or buts.
Laboratory next week (Experiment #4: Stoichiometry of Some Reactions of Copper). There are several pre-laboratory questions which will require stoichiometry calculations. Check these over. Todays lecture is important. Safety Issues: You will be working with nitric acid and sodium hydroxide. These reagents must be handle carefully! The reaction with copper metal and nitric acid MUST be performed in the hood to minimize air pollution in the laboratory. The brownish poisonous gas which is produced is not good for the lungs. Heat the solution in Step #2 slowly and carefully for best results.
Do the pre-laboratory questions before coming
to laboratory!!! If you do not the teaching assistants have
been authorized to deduct 6 points from your final laboratory score
for Experiment #4. Be sure to read your experiment before class. The
experiment is long and the more you understand before beginning the
experiment the more efficient you will work.
How do you tell if a reaction is an oxidation-reduction reaction??? If the elemental form of a substance dissappears or appears in the reaction, or there is a change in the number of oxygen atoms around another element the reaction is an oxidation-reduction reaction. Examples coming.
Return Examination Policy: Exams will be returned in laboratory next week. You will have your laboratory period to review the examination to see if any problems require re-grading. To have your examination re-graded return to your TA (not to Dr. G) while you are still in laboratory! Your exam will be check to be sure the question(s) were graded properly. Check the WEB to view the key and for comments on how exam was grade.
Problem Set #4 due on Wednesday, October 1st.
