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.

Lectures - MWF, 9;00 – 9:50, 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 in the secretary’s office and outside the lab. 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. Make sure and show up with
your $5 lab deposit plus $3 copying fee that first week.
a. The final grade is based on the number of points obtained out of
a possible 600 points. The points will be distributed as follows:
intro/biography 5 points (01%)
quizzes 60 points (10%)
hour exams 300 points (50%)
final exam (cumulative) 100 points (15%)
laboratory 135 points (28%)
total 600 points (100%)
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.
A word about learning chemistry. Studying chemistry is hard work for
most people (this is certainly true for me). 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. A chem 111 study coordinator
is also available (Phil Levesque,
firstname.lastname@example.org ). 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. 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. Makeups will be administered only if I deem the reason for absence to be legitimate and I am made aware of the absence beforehand. Each documented, unexcused lecture absence beyond the first two will cost you one point from your total.

Unsafe behavior in Lab will not be tolerated. Repeated unsafe behavior will result in a zero for that lab. In lab: 1) Goggles must be worn at all times; 2) No eating, drinking, or smoking; 3) No horseplay; 4) No unauthorized, "independent" experiments; 5) No sandals (enclosed shoes only); 6) No shorts (long pants only); 7) Additional safety rules given in Lab. You are expected to read the safety information in the Lab Folder and to come to lab each week well prepared. Report all accidents and injuries immediately. Know the location of all exits and emergency equipment (fire extinguishers, fire blanket, eye wash, showers, etc.) When in doubt, ask.
Wearing contact lenses in lab is highly discouraged. If you do wear them in lab, please let the lab instructor and the lab assistant know (you will not be penalized - it is good to know in case of an accident). Wear older clothes - they could be stained or ruined. Above all, use common sense and your chemical intuition - THINK. As a student chemist, you will be working in many situations which 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. Make a copy of each notebook page with carbon paper.
Lab reports consist of the report form, sample calculations, and any graphs or other material needed. Graphs should be on proper paper, fill the page, show data points in ink, have linear (or proper) scales with units and labels on axes. Data from unknowns and values determined from the graph should be clearly marked. Additional instructions will be given in the prelab lectures. For all parts of Expt. 21, there are simple report forms indicating the presence or absence of the cations in question.
In order to make-up a lab, only absences notified ahead of time will be excused. Each lab section is very full, so all requests to make up a lab or attend a section other than your normal lab must go through Dr. Mahler. Students who simply show up at a different lab section will not be admitted to that lab. Prelabs are due at the start of lab, and will not be accepted late. Lab report due dates are given below - any changes will be announced in lab. The overall Lab grade will be scaled to 135 points (see course syllabus).
