Description: CH 115 General Chemistry I (5 semester credits)
General Chemistry is the
introductory university level course for students pursuing further study in science. A solid foundation in chemical principles is
needed for continuing your studies in chemistry, biology, engineering, geology,
physics, health sciences and environmental studies. This course will work to emphasize the
integration of concepts and applications with factual information and to stress
approaches to both conceptual and numerical problem solving. Throughout the course, chemistry will be used
to understand everyday phenomena, to evaluate the risks and benefits
environmental issues, and be related to other disciplines.

Grading:
Course grades
will be derived from Assessments 75%, Homework 8% and Laboratories 10%, other (in-class
quizzes, participation, and attendance) 7%.
The laboratory work is a mandatory component for the course, a passing grade in the lab must be
achieved to receive a passing grade in the course. In the occasional circumstance where a
student is repeating this course, the laboratory is still required and must be
completed irregardless of their past laboratory experience. Assessments includes online quizzes, term
paper, scheduled tests and the final exam.
Grading is progressively weighted with later tests (whose content is
cumulative for the entire course to date) weighted more than earlier
tests. Scantron forms and #2 pencil are
required for each test/exam date and the first laboratory. Attendance at all class sessions is strongly
advised, graded activities will be included without further notice. If you find that the class sessions are not
meeting your needs please let me know how you feel we could change the
structure to assist you.
Exam Dates: Regular exams are scheduled for September
19, October 10, October 31 and November 22.
Please note the Final Exam date is:
Exams: Each student is advised to bring a personal calculation aid
with them to every class, laboratory and test/examination (abacus, slide rule
or calculator) - these cannot be shared during tests and should be capable of
manipulating scientific notation, logarithms and exponents. Only NON-PROGRAMMABLE SCIENTIFIC CALCULATORS may
be used during tests, quizzes and examinations. My philosophy regarding the memorization
of formula and physical constants is that each student can and will learn those
that they find useful and valuable on an ongoing basis. Therefore I, for this semester only, (don’t count on anyone else doing this)
will allow the use during any quiz or mid-semester test, in addition to your
personal calculator, pencil, and blank scratch paper, the use of one and only one 3”x5” conventional index
card. No card may be used on the course final – you must work toward
full independence by the end of the course.
This one card may contain any physical constants, formulas, sample
calculations, prayers and/or meditative verse that you believe you may find
useful. All information on the card must be handwritten. I will provide unusual or unique physical
constants for specific chemicals, bond energies, activities of metals, and
standard molar enthalpies, etc. Each
student may possess one and only one
card as described above, violations of this rule are considered academic
dishonesty - severe penalties will be enforced. It is vital that you report promptly for
exams, as no time extensions are possible.
Online Homework/Quizes: Success in General Chemistry is undeniably
linked to the amount of time invested in learning the material and problem
solving. Online quizzes and homework
will be assigned through the publisher’s website. Additional information on the assignments
will be given in class. Quizes must be
completed prior to the exam for each chapter, and must be completed within the
allocated time. Follow the WebCT links
to the additional resources for non-graded practice questions for each chapter
to test your knowledge and to reinforce and review for exams.
Writing Assignment
Each student will
write a term paper (between three and five printed pages, 1” margins, 12pt font
or less, double spaced) on any subject covered in the first semester of this
course (or the first 13 chapters of the textbook) that is of interest to him or
to her. “Topics might include the types of glass used in thermal heating,
graphite used in fishing rods and sporting equipment, diamonds, films used in
the motion picture industry, Teflon, nuclear reactors, penicillin, ether, etc.”
“The paper should
contain an introduction, a narrative section, and a conclusion. The
introduction should be fairly brief and explain why you’re writing the paper or
why the topic you’ve chosen is important or interesting. The narrative section
should contain some historical background, the information you’ve learned from
your reading and from your searching of the Internet and the basis for any
arguments you’re going to put forth in your paper. For example, if your paper
is on fats in the American diet and you think there is too much fat in the
average diet, you need to define what fats do, why fats are a necessary part of
the diet, what evidence there is that too much fat is eaten and what might
happen from eating too many fatty foods. Just saying that the average American
is over-weight because she or he eats too many fatty foods will not suffice. .
. . The conclusion should also be brief and contain your “take home message” or
the main points you’re trying to make in your narrative. For example,
continuing the fat-theme, you might conclude that the percentage of total
calories that originates from fats in the diet is more important than the total
amount of fat in the diet.”
At least three
references must be used, and one of these references must be a book or a scientific
journal that is actually in the library (the citation would include the page
number). “Some references to consider are: Scientific American, Nature,
Science, Chemical and Engineering News, Journal of Chemical Education, and
Chemical Heritage. The latter journal is especially good for historical
subjects.” Do not bother citing People,
National Inquirer, Time for Kids or the “Ask Dr. Science” archives.
Your paper will be
graded based on both content and format, spelling and grammar “count”. The paper will be counted in the final grade at
a weight equivalent to one of the course tests.
The introduction and bibliography are due Monday, October 3. The complete paper is due Monday, November
28. Turn in a paper copy AND an
electronic copy by email (dmyton@lssu.edu subject line: “CH115 paper”) You
may include the words written by others directly only when presented in
quotation marks and properly cited. You
may include the facts and ideas of others in any format only when you properly
cite the source. You may include your
own original work without restriction.
For example, this assignment is based on an article written by Dr. David
Newman at

A failing grade (F) can be assigned to students who commit acts of
academic dishonesty. At the instructor’s discretion this grade may be for the
assignment or the entire course depending on the nature and severity of the
offense. Academic dishonesty includes
but is not limited to cheating (the intentional use or attempted use of
unauthorized materials, information or study aids in any academic exercise) ,
fabricating (intentional or unauthorized falsification or invention of any
information or citation in an academic exercise), facilitating academic
dishonesty (Intentionally or knowingly helping or attempting to help another
violate any provisions of this code), or plagiarism (intentionally or knowingly
representing the words or ideas of another as one’s own in any academic
exercise). Definitions from the Code of Academic Integrity, University

Laboratory: Chemistry
is an experimental science. You are
encouraged to think independently about the data you collect and you will not
be graded solely on whether you acquire the right number or deduce the correct
explanation, but rather whether your explanations and hypotheses follow
logically from the data and that your reasoning is clearly stated. In the laboratory component of this course
students may OCCASIONALLY work
together in teams of no more than two, as
directed by the instructor. Each student
team member is responsible for assuming an equal share of the lab responsibilities
and work load. Students are to prepare
the pre-laboratory assignments before coming to lab, and to complete and turn
in their own laboratory reports as assigned.
Students are advised to read the laboratory procedures and carefully
plan their work to maximize efficiency and guarantee success. If you must be absent from a laboratory
session you should contact your laboratory instructor and attend one of the
other sessions that has available space within the next week. Missed labs cannot be made up after the end
of the week following the scheduled lab.
