Course Catalog Description
Science and Engineering majors study atomic structure, chemical reactions, thermodynamics, electronic
configuration, chemical bonding, molecular structure, gases, states of matter, and properties of solutions. The
laboratory includes appropriate experiments.
Prerequisites: One year of high school chemistry and MATH 1314 (College Algebra). 4 credit (3 lecture, 3
lab).
Course Prerequisites
These are stated in the course description in the HCC catalog (quoted just above) and they are stressed again here for
emphasis. Lack of satisfactory completion of the course prerequisites are one of the main reasons that cause
students to do poorly in chemistry. Basic math and problem solving skills at the level of college algebra are
essential. If you are not sure if your prior coursework meets these prerequisites, come and talk to me or to the
department chair for advice. With the prerequisites satisfactorily completed (preferably with a grade of B or better),
you can be confident that you are well-prepared for this course.
Course Intent
This course is intended for students majoring in one of the physical sciences or life sciences, or for students who are
pursuing pre-professional programs in medicine, dentistry, pharmacy, veterinary medicine, or other health programs.
The course is also beneficial to students who are preparing themselves for higher level science courses in their
respective curricula.

Attendance Policy
The HCCS 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. Although it is the
responsibility of the student to drop a course for non-attendance, the instructor has full authority to drop a student
for excessive absences. A student may be dropped from a course for excessive absences after the student has
accumulated absences in excess of 12.5% of the hours of instruction (including lecture and laboratory time).”
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.
Last Day for Administrative and Student Withdrawals
This date is stated in the Schedule of Classes. After the withdrawal date no W can be given, you must receive a
regular grade (A-F) in the course. I urge any student who is contemplating withdrawing from the class to see me
first! You may be doing better than you think. Either way, I want to be accessible and supportive. I do not believe
in "weed out" classes, and I consider you to be much more than just a name or number!
If you need assistance, do not hesitate to contact me (my phone number and e-mail address are listed above). I'm
here to help.
IMPORTANT NOTICE:
Students who repeat a course three or more times may soon face significant tuition/fee increases at HCC and
other Texas public colleges and universities. If you are considering course withdrawal because you are not
earning passing grades, confer with your instructor/counselor as early as possible about your study habits,
reading and writing homework, test-taking skills, attendance, course participation, and opportunities for
tutoring or other assistance that might be available.
Disability Support Services (DSS)
HCCS is committed to compliance with the American with Disabilities Act and the Rehabilitation Act of 1973
(section 504)
"Any student with a documented disability (e.g. physical, learning, psychiatric, vision, hearing, etc.) who needs
to arrange reasonable accommodations must contact the Disability Services Office at the respective college at
the beginning of each semester. Faculty are authorized to provide only the accommodations requested by
the Disability Support Services Office”
If you have any special needs or disabilities which may affect your ability to succeed in college classes or
participate in college programs/activities, please contact the office of disability support services at the college.
Upon consultation and documentation, you will be provided with reasonable accommodations and/or
modifications. Please contact the DSS office as soon as you begin the term. For questions, contact Donna Price at
713 718 5165 or the Disability Counselor at HCC-Southwest: Dr. Becky A. Hauri at 713 718 7909; also see the
Schedule of Classes for additional DSS numbers.

Faculty Orientation is also available at http://www.hccs.edu/students/disability/faculty.htm
HCCS Sexual Harassment Policy
HCC shall provide an educational, employment, and business environment free of sexual harassment.
Sexual harassment is a form of sex discrimination that is not tolerated at HCC. Any student who feels that
he or she is the victim of sexual harassment has the right to seek redress of the grievance. HCC provides
procedures for reviewing and resolving such complaints through its Grievance Policy. Substantiated
accusations may result in disciplinary action against the offender, up to and including termination of the
employee or suspension of the student. In addition, complainants who make accusations of sexual
harassment in bad faith may be subject to equivalent disciplinary action.
Academic Honesty
Students are responsible for conducting themselves with honor and integrity in fulfilling course requirements.
Disciplinary proceedings may be initiated by the college system against a student accused of scholastic
dishonesty. Penalties can include a grade of "0" or "F" on the particular assignment, failure in the course,
academic probation, or even dismissal from the college. Scholastic dishonesty includes, but is not limited to,
cheating on a test, plagiarism, and collusion.
Laboratory Policy
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 manual. You will
be much better organized when doing the experiments, and your laboratory experience will be much more
rewarding!
Exams, Quizzes, and Make-up Policy
Examinations will consist of three non-cumulative regular exams (45%) plus a comprehensive final (20%).
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. 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.
During the semester I will periodically give a short chapter quiz at the beginning of class. I will drop the
lowest quiz grade. The remainder will count as a regular exam grade (15%) which cannot be dropped.
These quizzes are highly beneficial for learning the material and are intended to help you in this regard.
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.
Grading
The overall score is based on the following:
Three Regular Exams
Quiz Grade
45%
15%
Laboratory
20%
Final Exam
20%
Overall Score = 0.45(Average of three regular exams) + 0.15(Quiz Grade) + 0.20(Laboratory
grade) + 0.20(Final Exam)
The course grade is then obtained from the overall score:
Final Average
Letter Grade
90 - 100
A
80 - 89
B
70 – 79
C
60 – 69
D
< 60
F
Other Information
Free chemistry tutoring is available. A tutoring schedule will be posted in the classroom and lab and will also be
placed on my web site and departmental web site. There are many interesting chemistry resources on the Internet.
These are interesting and informative, but spending long hours searching for sites or waiting for graphics intensive
sites to load, is not beneficial! Your best immediate source of information is your textbook - make thorough use of
it.

General Suggestions
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, the major topics we will
be covering are Chemical Formulas, Reactions, and Stoichiometry Calculations, Gas Laws, Chemical
Thermodynamics, Electron Configuration, Chemical Bonding, and Solutions. As you might suspect, it
can be easy to fall behind and, as a result, to not be ready for the exams. Following are some general tips
that may be helpful:
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. I 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, x2, , 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!
