Exams, Quizzes, and Make-up Policy
Examinations will consist of three non-cumulative regular exams (45%) plus a comprehensive final (20%) and combined quizzes (15%). Make-up exams will not normally be given, so make every effort to take the exams on their scheduled dates. In the event that you must miss one and only one regular exam, the final exam grade may be substituted for the missed exam or the combined quizzes average. Remember that the final exam will be comprehensive and is usually more difficult than the regular exam (meaning that it will cover all of the material from the whole semester, not just the last part). If you do not miss any of the regular exams, I will replace your lowest exam score with your final exam score if the final exam grade is higher.
Please note:
1) All students are required to take the final (no student can be exempted),
2) After the withdrawal date, a grade of W cannot be given.
3) All students are responsible for keeping track of their own grades. Exams and labs will be returned to you in
a timely manner. Please keep records of your own grades.
Grading
The overall score is based on the following:
Grade Evaluations

Laboratory Safety and Requirement Policies
On the first day of lab a safety video will be shown (about 35 min long) and a safety "quiz" will be given and reviewed. Each student will then sign a statement affirming his or her commitment to following safe procedures in the laboratory, and turn the form in to the instructor. You should be especially aware of the need for adequate eye protection and proper dress in the laboratory. Glasses or goggles must be worn at all times during the laboratory period . Any student not wearing glasses or goggles after the experiment has begun may be given a zero for that experiment! Experiments will be performed in groups of up to two students each. Before you leave the lab, be sure to show me your report so I can review and initial it . Each student should arrive at the lab on time , with his or her lab manual. Laboratory reports are due on or before the next lab experiment . Each report must be done individually, but of course you can work with your lab partners. If you are not sure about a calculation or a particular section, always feel free ask me about it! Each report will be graded on a 100-point basis. Come to lab prepared . Read through the experiment beforehand, and review the pre-lab questions and answer them in the lab report. You will be much better organized when doing the experiments, and your laboratory experience will be much more rewarding!
Note Attendance, performance of assigned experiments and completion of data sheet required for each lab. No absences are accepted.
A) The lab work and the lab assignments together are 20% of the overall grade.
B) A complete lab report has 3 parts:
(1) Pre-lab report: This includes writing procedure for the experiments to be performed on that day and answering any assigned lab questions. It needs to be completed before starting the labs.
(2) In-Lab report: This includes writing all observations, calculations, results, and discussion. It needs to be completed in lab.)
(3) Post-lab report: This includes answering assigned lab questions, if any. Lab reports are due either same day of the lab completion or the following lab period. (Check with instructor)
C) Students will work in lab individually or in-groups of two. Each student has to submit an individual lab report on assigned due date. Late assignments will not be accepted and a grade of zero will be awarded for the experiment.
D) There is no formal lab exam. Lab grades will be assigned on punctuality, attendance, work ethics, completion of the experiment, and the lab report. Students who arrive late for the lab or have an unexcused absence from the lab will lose 25% of the lab grade for each occurrence.
E) Make-up for one missed lab is not allowed. A grade of zero will be awarded for that experiment.
F) Students must complete all laboratory assignments. Students must arrive on time to do the lab. If you arrive 15 minutes after the lab starting time you’ll not be allowed to perform the experiment. Also come with proper clothing and shoes to the lab.
G) Each student is required to follow all the safety procedures in the lab, such as, wearing safety goggles
while doing a lab. Detailed orientation for safety will be given during first week of lab. Community lab coats and safety goggles are available in lab for individual use, but you will have to buy gloves to wear when needed.
H) All students working in chemistry labs should be aware of the inherent dangers, which exist even though the instructor has taken utmost precautions. It is therefore important for each student to behave responsibly and report any irresponsible behavior to the instructor. Students guilty of irresponsible behavior will be dropped from class.
I) Only experiments that are assigned by the instructor are to be performed. All other experiments are prohibited.
J) Any accident in lab, no matter how slight, must be reported to the instructor immediately.
4

Incomplete Grade (I)
An incomplete grade can be awarded under extraordinary circumstances, only if 90% of the course has been completed. For example, at the end of the semester, if you miss one exam, one lab or the final due to sudden illness, family emergency, catastrophic accident etc., you can request for incomplete grade with proper documentation.
Each student must sign a written contract prior to the “I” being given. Without paperwork no Incomplete will be given. If the missing work is not completed in the specified time (details are available in the ACC student handbook), a grade of 'F' will be awarded. An Incomplete grade does not allow a student to retake the entire course to improve their grade.
Class and Attendance Policies
The Alvin College attendance policy is stated in the Schedule of Classes.
Students are expected to attend classes regularly. Students are responsible for materials covered during their absences, and it is the student's responsibility to consult with instructors for make-up assignments. Class attendance is checked daily by instructors. Should a student miss a lecture or lab, he or she is responsible for asking classmates what he or she missed.
If circumstances significantly prevent you from attending classes, please inform me. I realize that sometimes outside circumstances can interfere with school, and I will try to be as accommodating as possible, but please be aware of the attendance policy.
A.
If a student needs to drop the course, it is the responsibility of the student to follow the correct procedure and deadline(s) to officially drop or withdraw from the course (details are available in the ACC schedule handbook). A student may receive an "F" in the course if fails to officially drop or withdraw from the course.
B.
Students are expected to attend class regularly. The course cannot be completed if the absences exceed more than 2 weeks in the semester of instructional period.
C.
Student should work independently on all assignments and exams delivered in the class (unless instructed to work in groups). In case of scholastic dishonesty (any type of cheating, copying, etc.), no credit will be given for the particular assignment and the student may receive an “F” in the course.
D.
Responsible adult behavior is expected in the classroom. Failure to exhibit adult behavior will result in dismissal from class.
Last Day for Administrative and Student Withdrawals Instructions
For Spring 16 weeks classes, this date is in college catalogue .

Chemistry is a vast field, ranging from the study of simple inorganic salts to enormously complex molecules such as enzymes and nucleic acids in living organisms. In this course, we will be covering chemical kinetics, equilibrium, pH and buffer solutions, thermodynamics, electrochemistry, nuclear chemistry, and organic chemistry. A professional chemist may devote his or her entire career to only one of these general disciplines; we have a semester to touch on all of them! Here are some general suggestions:
Learning chemistry takes time. A reasonable guide is to allow yourself two hours of study for each hour of lecture. Heavy work and/or class loads are not compatible with learning chemistry!
Attend class regularly (!) and take generous notes during class. Ask questions.
When beginning a new chapter, I recommend that you read through it quickly the first time, just to give yourself a good feel for what it is about. If you are really on the job you will have done this before the class lecture on the chapter! You will understand what's going on in class much better if you do this.
Next, start tackling the end of chapter problems! Often, working problems facilitates understanding much better than just reading and rereading the chapter itself. Chemistry is a "hands on" course - working problems is essential. However, do not spend an inordinate amount of time on a single problem - skip it for the time being and go on to another. Try working some of the sample exercises.
They are worked out in the chapter and are very helpful.
Get a good, scientific calculator that has scientific notation ("EE" or "EXP" key), log, ln, x
2
,

, etc.
Business calculators usually do not have all of these features.
Review basic math operations such as properties of logarithms, if you are rusty.
Study groups can be very helpful. Keep the group small though, no more than three or four people.
Finally, keep a positive attitude! Chemistry can be hard, but with the right attitude and approach, you will succeed in mastering it!
I hope you find chemistry to be an interesting and rewarding subject which will not only be useful in your academic major, but will give you a better insight into the many scientific challenges we are facing today.
I look forward to working with you this semester!
