Course Overview: Welcome to the third term of college chemistry!!! In this course we will finish up the vital material of general chemistry, electrochemistry. However, most of our time will be spent on the application of general chemistry to special topics. The topics have been chosen with an interest in biology in mind. I hope you will think of this course as the reward for your hard work in CH121 and CH122.

Course Content: This course will cover topics in Chapters 20, 21, 24 and 25 of Chemistry: The Central Science, 10^th Edition by Brown, LeMay and Bursten. In addition, we will cover topics in organic and biochemistry that will be covered in handouts and lecture notes.

Course Objectives: The student should…….

Understand and be able to apply the concepts of electrochemistry.
Be familiar with general concepts of nuclear chemistry
Be familiar with structure and nomenclature of coordination compounds.
Be comfortable with the nomenclature and properties of general organic compounds and functional groups.
Be comfortable with the notion of chirality, or stereochemistry.
Understand, in general, nucleophilic substitution and elimination reactions in organic chemistry
Know the structures and functional groups of the primary biochemical compounds.
Appreciate the basic concepts of metabolism and metabolic enzymes

***PLEASE NOTE: I reserve the right to use a more lenient scale.***

Your grade will be determined based upon your performance on 2 in-class exams, 6 in-class quizzes, group worksheets/assignments (W) and web assign on-line homework (H), a group project, the final exam and your laboratory work with the following distribution:

Exams 37%

Quizzes 10%

W+H 8%

Group Project 5%

Final Exam 20%

Lab Work 20%

Exams: Two exams are scheduled for April 7^th and April 30^th. The exams are intended to require about 45-50 min to finish. You will have up to 1 hour 20 min. The exam questions will resemble those on quizzes, worksheets, and on-line homework. I reserve the right to ask you to use a departmental calculator during exams.

Quizzes: This 10% of your overall grade will be short exercises given at the end of class that you must do on your own. They are scheduled for Fridays during week 1, 3, 6, 7, and 9, and Wednesday of week 10.

W+H: This 8% of your grade will consist 50% of grades on group worksheets/assignments (W) and 50% on WebAssign^TM on-line homework assignments (H):

· Group Worksheets/Assignments: There will be in-class, open-book group assignments 2-3 times per week to be turned in at the start or end of class or by 5PM that day, as instructed. Each group of 3-4 students may turn in one group worksheet. These exercises will include problems such as those covered in the lecture that day so you can apply your new knowledge before leaving class.

· On-line Homework: Sets of on-line homework problems will account for the remainder of your W+H grade. The assignments must be completed no later than 11:59PM on the due dates, which are shown as “WA” on the class schedule. You will access and submit these assignments at http://webassign.net/student.html . You must purchase an access card at the bookstore. Instructions for using “WebAssign” are posted in the public folder for this course.

· Additional Practice Problems: Problems from the end of the chapter will also be assigned. I STRONGLY recommend that you complete all the assigned problems since they will aid you in learning how to do graded homework problems, and in preparing for quizzes and exams. Additionally, there is a companion web site for your textbook which provides additional exercises – see the introductory material in your book.

Group Project: The class will be divided into groups of 3-4 students who will work together to present a chemistry case study to the class during week #10. The case studies will be assigned from websites such as http://www.chemcases.com. More detailed information will be provided in a separate handout.

Final Exam: Every student is required to complete the final exam. The final will include new material covered after Exam #2, as well as more comprehensive/cumulative topics. The final is scheduled for 9-11am on Monday, May 19^th. Note: I cannot and will not reschedule your exam without approval from the Dean of Student’s office!!!!!

Lab Work: As noted in the schedule, a portion of class each week will include a introduction of the experiment to be done that week. However, I will not be your lab instructor. If you would like to know how you are doing in lab, contact your instructor. At the end of the term, your lab instructor will provide me a grade for you and this will account for 20% of your total class average.

Make-Ups and Late Work:

Exams:

· It is your responsibility to take exams at the time they are scheduled.

· General policy is that make-up exams are not permitted. However……If you must miss an exam and expect the option of a make-up exam – You must contact the instructor within 24 hours.

· Your request for a make-up exam will depend upon the validity of your reason for missing. The instructor has the final say in the matter.

· Make-up exams must be completed before exams are handed back to the rest of the class.

· The final exam time is set by the college, not the instructor. I cannot and will not reschedule your final exam without approval from the Dean of Student’s office!!!!!

Quizzes:

· There will be no make-ups for quizzes, no matter the reason.

· The lowest one of the six quiz grades will be dropped. This includes one missed because of an absence for any reason. If you must miss more than one quiz due to an extended illness or college-sponsored academic or athletic activities please see the instructor to make special arrangements.

W+H:

· There will be no make-ups for worksheets or on-line homework, no matter the reason.

· The lowest 20% of worksheet grades will be dropped. No on-line homework grades will be dropped.

· Late worksheets will be docked 10% per day and will not be accepted once they have been handed back.

Group Project: You are expected to participate fully in the project and turn it in on time. You will be penalized for any lack of participation or late work.

Information Technology Services: Every student should become at least partially literate in the area of information technology, since it has become such an integral part of the education process. Students requiring assistance with the use of information technology should take advantage of the resources available to them in the Olin Center. Besides student consultants who can provide aid in the computer labs, there are other opportunities for tutoring or training by the ITS department. For example, free one hour classes are offered to students in various subjects, such as Photoshop, Digital Video, and more. Watch for notices in your e-mail for dates and times of these classes. For additional information, go to http://its.augustana.edu/students.html .

Using WebAssign:

In order for you to complete the on-line assignments during the term you will need to log on to http://www.webassign.net/student.html . You can do these assignments using any computer that can connect to the Internet; such as those in the computer centers throughout campus. The only exception is that the America On-line 4.0 browser is incompatible with WebAssign. You will have three chances to submit submit your answers.

Important points to note:

1. In order to log in, you need a username and password.

Þ Your username will be your first and last names in lower case with no separation (e.g., johnsmith).

Þ Your password will be your student ID number (leave out zeros at the beginning).

Þ You will also need to enter the word "augustana" when asked for the institution.

Þ Within a few days after the beginning of the term, you must register by entering coded information you get from the WebAssign materials you purchase at the bookstore.

2. Do not wait until the last minute to do your assignment…….there are no “make-ups” for on-line homework.

3. Before you begin the first on-line homework set, click on "Student Guide" at the left-top of the log in screen, and then select topics from the list on the right side of the screen in order to learn how to use WebAssign.

4. When doing your assignment, be sure to always start with a fresh copy of the browser. If you use a terminal where a previous user has not logged off the browser completely, WebAssign will not know who is doing the assignment! Also, “reloading” a page is not recommended. You must also log off the browser completely after you have submitted your assignment for grading.

5. If you exit the browser before you submit your answers for grading, you will lose all of the work you have entered. You will have to start again from the beginning, often with altered problems. Since computers sometimes crash, it is wise to keep a paper record of your work and answers.

6. WebAssign has little (if any) imagination and does not assign partial credit. Thus you need to enter your answers in the way that the computer can understand. Follow any directions given for the problem. In general, answers with typographical errors will be marked incorrect. Be very careful to spell words correctly and to check your arithmetic before submitting your answers. Often the correct format of an answer is crucial. For example, if you wish to enter the number 0.002586 in exponential notation, only 2.586e-03 or 2.586e-3 will be recognized by WebAssign. Often the required format of the answer will be specified in the problem, so you need to read questions very carefully.

7. The proper use of significant figures is important. Normally WebAssign expects calculated results to have three significant figures. (Recall that counting significant figures is not the same as counting decimal places.) However, in problems where strictly applying the rules of significant figures is important, answers with the incorrect number will be marked incorrect. In multi-step problems, it is wise to keep all the figures in your calculator until the problem is completed. You may have to round the value in your calculator to get the correct number of significant figures for the answer to an early step, but it is unsafe to use this rounded number to get answers for later steps.
