Spring 2006                            General Chemistry II                        Lycoming College

 

 

Course description - This course is designed to look at ions/molecules in dynamic situations.  We will focus on chemical reactions and various measurable parameters associated with reactions (equilibrium constants, energy, rates of reaction….).  Applications of these ideas to everyday life will be discussed whenever possible.

Course format

Lectures - MWF, 11:30 – 12:20, HBC G09, Attendance required.

 

Recitations - Thursday, 7:45 - 8:35 am and 1:00 - 1:50 PM, HBC G09.  The primary method for evaluating chemistry students in testing situations is to have them work problems.  In recitation we will practice the same sort of problems you will see in testing situations.  Attendance expected.  I will not take attendance but I might use some of the examples discussed in recitation as exam and quiz questions.  I have found, that on the average, students who attend recitation in my courses get an average of one full letter grade higher than those who don’t attend

Assigned homework - Problems designed to enhance your understanding and prepare you for testing situations.  A key will be posted on the web (I'll provide a web address soon) and outside my office.  Homework will not be collected.  A large chunk of recitation will be devoted to working these problems.

 Laboratory -  Here you will experience what chemists actually do.  Your labwork will be evaluated as described in the lab.  A lab syllabus will be distributed at the first lab session.

 Grading scheme

a.   The final grade is based on the number of points obtained out of a possible 600 points.  I suggest trying to get as many of these points as possible.  The points will be distributed as follows:

 

      quizzes                                                                  60 points (10%)

      hour exams                                                          300 points (50%)

      final exam (cumulative, standardized)*              110 points (18%)

      laboratory                                                            130 points (22%)

      total                                                                     600 points (100%)

 

*a higher score on the final exam can be used to replace a lower score from exam 1-3.

 

As always you will have the opportunity to obtain bonus points through attendance at our colloquium series.  Assuming you stay for the whole show and you mind your manners you will receive 3 points per colloquium.  You may also receive up to 6 bonus points by writing a paper on a topic that we have mutually agreed upon (2-3 pages, typewritten, double spaced, with a minimum of 2 bibliographic sources.  The ceiling on bonus points (excluding bio assignment and those on exams) is 12.

 

Guidelines for Attending Colloquium:

i.    Be on time.

ii.   The speaker has expended a lot of effort to prepare for the talk.  Be attentive and polite.

iii.  If you can’t stay for 45 minutes for an internal speaker or 60 minutes for an external speaker, don’t come (please do not ask the speaker how long the talk will last).

iv.  Realize that questions for the speaker at the end is part of the talk and you will be expected to stay for that as well.

 

 

b.   Assignment of letter grades is based on the following scale:  540 - 600 A, 480 - 539 B,            420 - 479 C, 360 - 419 D, < 360 F.

 

c.       A word about learning chemistry.  Studying chemistry is hard work for most people (this is certainly true for me).  Thoreau said, “The cost of a thing is the amount of what I call life which is required to be exchanged for it”. Chemistry will certainly cost you a lot of effort (we wouldn’t have it any other way!)   I would recommend that you work on the lecture material at least one hour per day outside of class for starters.  Once you see how things are going this amount can be adjusted as needed (I suggest a significant increase in study time prior to an exam).  If you are having trouble, make sure and come and see me.  I’m easy to talk to and will do whatever I can to help you.  You will be responsible for all of the material listed on the following schedule for the indicated exams and quizzes.  It is not sufficient to learn the material from the lecture alone.  You are expected to read and think about the material prior to the lecture.  I also suggest you work problems, LOTS of problems. We must necessarily cover a large amount of material so our pace must be geared towards those who are ready to learn.  The hour exams will be somewhat cumulative in the sense that we need to know the earlier material to comprehend the latter. 

 

Policy on attendance

Attendance at quizzes and exams is mandatory.  No makeups will be administered.  If I am made aware of the absence beforehand and I deem the reason for the absence to be legitimate, later tests/quizzes will be averaged and used for the earlier missed exam or quiz.  Each documented, unexcused lecture absence beyond the first two will cost you one point from your total.

GENERAL CHEMISTRY 111—Laboratory

Dr. Jeremy Ramsey

Heim 232

321-4103

 

            The labs for Chem 111 consist of two quantitative analysis experiments followed by a series of qualitative analysis determinations and then two investigative labs.  Grades in lab are much more dependent on the accuracy of your results than was the case in Chem 110.  In most experiments, students will work individually on their own unknowns.  You are welcome to consult with your friends and neighbors, as well as with the teaching assistant and instructor, but please remember that your grade ultimately depends on your own work.

 

             Please note the following reminders concerning lab safety.  Unsafe behavior in Lab will not be tolerated.  Repeated unsafe behavior will result in a zero for that lab.

 

 

All accidents and injuries must be reported immediately.  Know the location of all exits and emergency equipment (fire extinguishers, fire blanket, eye wash, showers, etc.)  If you are unsure if you are performing a technique safely, please ask first.  Wearing contact lenses in lab is highly discouraged.   If you do wear them in lab, you MUST inform the lab instructor and the lab assistant and you MUST wear a full goggle.  Wear older clothes - they could be stained or ruined.  Above all, use common sense and your intuition—if it seems dangerous, ask first!  As a student chemist, you will be working in many situations that demand your utmost care and attention to protect the safety and health of yourself, your fellow students, and the environment.  Preparation and careful, patient work are needed to obtain the results required in each experiment.

 

            Your Lab Notebook should be neat, well organized, up-to-date and complete, with a Table of Contents.  Leave room to record your data, the uncertainties in measurements, and any observations about the experiment.  Use a different notebook page for each day’s data, and submit the carbon at the end of the lab period.

 

            Lab reports consist of the already submitted carbon copies of your notebook pages, the appropriate report form, sample calculations, and answers to any questions.  Additional instructions will be given in the prelab lectures.  For all parts of Exp. 21, there are simple report forms indicating the presence or absence of the cations in question.  Lab reports are due at the beginning of the lab as shown on the schedule below - any changes will be announced in lab.  Late labs will be penalized 10% plus 1 point per day late (weekends count as one day) and can be turned in no later than two weeks from the original experiment date.  Prelabs are due at the start of lab, and will not be accepted late. 

 

            In order to make-up a lab, only absences notified ahead of time will be excused.  All requests to make up a lab or attend a section other than your normal lab must go through me.  Lab make-ups must be scheduled by the end of the week that the lab is missed and must be completed by the end of the following week. Students who simply show up at a different lab section will not be admitted to that lab.
