1. CHEM 101---------Please read along in your textbook and practice working problems as the information is completed in lecture. We will be covering material in chapters 9 and 10 of your text. There are links on the Information Sheet where the topics of vaporization, boiling, and mechanical refrigeration are discussed.
End of semester reminders:
Make up exams will be administered on Tuesday May 5 at 9:30 am and 2:00 pm and Thursday May 7 at 9:30 am in SBA 240. To be eligible for the comprehensive make-up test, you must have submitted a written excuse and had that excuse accepted by me as an excused absence. You must notify me in writing no later than 4:45 pm Wednesday April 29, indicating which of the above dates and times you intend to attend for the make-up exam.
The optional extra credit assignment is due Wednesday April 6. The assignment along with any UCM passes will be collected at the beginning of class.
The final exam is scheduled for Thursday April 14, at 2:45 pm in the same class room. You will need a type F scan form and calculator.
Early graduating senior exams will be scheduled for an earlier date once the list of prospective graduates is generated.

2. CLAB 124-------Please be prepared for the final exam on experiments 4 - 10. You will need a type F scan form and calculator.
NOT: You should read the introductory material and the procedure in your lab manual (or modification if applicable). Be sure to prepare an outline (summary) of the procedure in your notebook. Remember to bring your lab manual and notebook to class and wear proper lab attire. Please also bring a calculator (does not need to be scientific). Please study the link on the class web page for Common Laboratory Operations and Apparatus.
Your lab report for experiment 10 will be due. Please read Part II of the Information Sheet before starting the report. Remember that all calculations are to include units and are to be to the proper number of significant digits. Multiple pages must be stapled.
Raw data: A-voltages of single cell, parallel and series connected cells.
C- Masses of + copper electrode before and after and - copper electrode before and after. Table of current vs. time.
Sample Calculations: A- Theoretical value of voltage - single cell, series connected.
C- Calculate Faraday's constant as I did in class for + and - electrodes. Calculate % error for each electrode.
Results: A: Give measured and theoretical voltages for single cell, parallel and series connection.
B: Give 6 reactions. Put a check above the arrow for reaction that occurs and an X above the arrow for the reaction that does not occur. Finally, give the activity series.
Give the values you calculated for Faraday's constant and the % errors for both electrodes.
Discussion: Discuss your results.
Your optional extra credit along with any UCM passes will be due at the time of the final exam.
