ACHM 112 - Spring 2008

Syllabus for Sections 1 and 2

Dr. Kutty Pariyadath

 

ACHM 112 is the second half of the two-semester General Chemistry sequence. Successful completion of ACHM 111 is a pre-requisite for ACHM 112. Since most of what was learnt in ACHM 111 will be needed to understand the chemistry taught in ACHM 112, those who earned a 'D' or 'D+' in ACHM 111 are urged not to take ACHM 112 until they have retaken (and earned a grade 'C' or better in) ACHM 111.

ACHM 112 is a 4-credit course.

Course Objectives: The purpose of this course is to continue to provide instruction in the fundamentals of chemistry that may then be applied to other courses for which chemistry is a pre-requisite. As in the case of ACHM 111, this course also involves the vocabulary of chemistry, the processes of chemistry and the quantitative aspects associated with data collection and interpretation of results.

The topics covered are fundamental to the study of the physical world and include, chemistry of the transition metals, rates of chemical reactions, general principles governing reactions that do not go to completion (or equilibrium reactions), acid-base equilibria, ionic equilibria including complexation and precipitation equilibria, thermodynamics, redox reactions, and electrochemical cells. In addition, brief introductions to organic chemistry, biochemistry, and nuclear chemistry will be provided.. All of these topics are quite relevant to the study of the chemical processes that take place in chemical, biological and geological systems as well as to the study of many processes that are applicable to the various fields of engineering.

In order to get a good grasp of the chemistry that we will cover, you should read the topics in the text, attend classes regularly and take notes and/or tape the lectures, solve the sample problems in the chapters, and solve as many problems at the end of the  chapter as possible. At the least all of the assigned homework problems should be done with the intention of learning the associated chemistry. In case of any problem with any of the topics, you should seek my help, in my office or in class, as soon as possible. Staying with the class will help prevent falling behind in a subject that is built vertically and makes recovery quite difficult.

If your goal is an 'A' in this course, then it is imperative that you understand all of the topics covered to the extent of being able to answer all of the homework and test questions on them. This may take only a few hours of studying for some of you but many more for the others. If, for whatever reasons, you have set your sights lower than an 'A', then it is not fair to expect to be able to answer all of the questions on any quiz or test.

 

Quizzes and Tests: There will be a quiz every week, except when tests are scheduled. Quizzes will include topics covered both in the lecture and in the lab. Ten quizzes will be counted towards your grade. Some of the quizzes will have multiple choice questions. There will be three tests, each covering several chapters. The final exam will be the American Chemical Society's General Chemistry Examination, which includes questions from topics covered in both 111 and 112. Those who expect to pass this course must take the final exam.

 

Academic Integrity: You are required to follow the USCA Honor Code in all assigned work that will be graded, be it a quiz, test, or homework. Details on academic integrity are given in the USCA Student Manual for 2005-2006, and you are urged to review this information since violators of academic integrity will be prosecuted according to the guidelines in the manual.

 

HOMEWORK: Problem solving is an integral part of learning the concepts in chemistry. Many sample problems and end-of-the-chapter problems will be solved in class. Additional problems will be assigned using Webassign, a web-based technology for assigning, completing and grading homework. Each of you will sign up for homework using Webassign. In order to sign up you have to follow the procedure below:

 

1.      On the internet explorer, type in www.webassign.net

2.      Click on sign in which is in the left margin.

3.      Type in your USCA email address without the .edu in the space for User name.

4.      Leave the space for institution blank

5.      In the space for Password, type in the last 4 digits of your SS# and click on  log in

6.      On the page that comes up, click on the down arrow next to choose your access code prefix and select the 2-digit prefix of your access code that came with your textbook if you bought the book at USCA bookstore. If you bought your book elsewhere, click on PURCHASE AN ACCESS CODE online and follow the procedure. You will have to pay using a credit card online.

7.      Steps 1-6 registers you in the course and you have now access to all of the assigned homework and related information.

I expect to assign 3-5 homework problems after each lecture. Each homework assignment will have a starting date and time, usually after the lecture, and a deadline usually before the next lecture. The homework deadline will not be extended. Since homework will be based on the lecture material, you should be able to do them if you are up-to-date with the topics covered in class. Obviously, the purpose of assigning the homework is to improve your understanding of chemistry and, thereby, your grade. If you are able to successfully complete all the assigned work, including the homework assignments, correctly without external help, you should earn a good grade in the course. 

Note that you may be offered more than one opportunity to solve some of the homework problems. I hope you will take advantage of these additional opportunities.

Just remember that your poor performance in quizzes and exams resulting from not doing the homework yourself will more than cancel any points gained from cheating on the homework.

Lab Activities: The class will be divided into groups of 2. Each group will carry out each lab activity. Sometimes a given activity may be divided among several pairs such that the data collected will be shared by the whole class. It is imperative that you read the lab introduction and procedure prior to the action and write a summary before coming to class. These summaries will be collected at the beginning of the period. Two points are assigned to each such pre-lab write up and 5 points to each lab report. More work than you put into ACHM 111 is expected in both the summary and the report in ACHM 112

 

Required Dress and Conduct in Lab:

·        Long pants/skirts

·        Closed top shoes (absolutely no sandals or flip-flops)

·        Must always wear safety goggles when in the lab (you may take them off in the hallway only)

·        Long hair should be pulled back completely away from the face.

·        No portable electronic devices are allowed in the lab (excluding your calculator)

·        No food or drink allowed in the lab.

·        No horseplay.

 

Attendance and In-class Behavior: Attendance of all class meetings is expected, though excused absences are understandable. An attendance sheet will be passed around each class period for you to sign. Any student who has more than 10% unexcused absences will be assessed a one letter grade penalty off the final course grade. Any student who has been absent (excused and unexcused) more than 25% of all class meetings will receive a failing grade for the class. Unexcused absences on exam days will result in a grade of 0 for the exam. Unexcused absences on lab days or quiz days will result in a 0 for that assignment. Exams for people with excused absences must be made up as soon as possible at a time convenient to the student and the instructor. If you have an excused absence on lab or quiz days, these assignments do not have to be completed. The maximum points possible for this course will be altered to reflect this change if you missed more than one  quiz due to excused absences. Excused absences require a doctor’s note, a note from a family member that includes a telephone number to check, a business note, or a receipt (in the case of car problems). Please contact me with any questions on this topic.

 

Please respect your classmates’ right to pay attention to the instructor. Therefore, please don’t start, or participate in, any conversation or other activities while the instructor is engaged in teaching activities. If you choose to this request, you may be asked to leave the classroom.

 

Cell Phones: You must turn off your cell phones and put them away at all times while in my lecture class. If you expect an emergency call, please let me know ahead of time and I will allow you to keep the cell phone on. If such an emergency is expected during a quiz or test, I will keep your cell phone at my desk. If at any time I see your cell phone out, I may ask you to leave the room.

 

Disabled Student Policy: If you have a physical, psychological, and/or learning disability which might affect your performance in this class, please contact the Office of Disability Services, 126A BSED, (803) 641-3609, as soon as possible. The Disability Services Office will determine appropriate accommodations based on medical documentation
