Chemistry 107: Survey of Chemistry
Fall 2006
Chem 107 is the first of a 3 quarter series covering the fundamental concepts of inorganic,
organic, and biological chemistry and is intended primarily for students in various healthrelated programs. While no previous chemistry is required, high school chemistry or
Chem 101 (100) is strongly recommended. Chem 107 requires modest proficiency with
algebra; as such Math 65 is a prerequisite. The suggested reading level for Chem 107 is
Read 98 (or higher placement) and a ‘C’ or better in English 099 (or higher placement) is
required.
Chem 107 will develop the central concepts of measurement and determination of physical
properties; scientific and analytical methodology, the nature of atoms, molecules, and
ions; bonding between atoms and molecules; mass relationships and stoichiometry;
solubility and solution chemistry. Additionally, Chem 107 will focus on chemical reactivity
in terms of equilibrium and kinetics. Acids, bases, and pH will be considered in some
depth, and oxidation and reduction will also be developed. The course will be presented
within a framework of practical relevance, and should provide a “chemical scaffold” on
which to interpret physical phenomena, with examples geared towards the health science
student. Chemistry 107 fulfills the requirements for a general education core class at
WWCC.

Grading:
The Grading for Chem 107 will be as follows
 3 Examinations2
 Exam I = 100 points (20%)
 Exam II = 100 points (20%)
 Final Exam = 100 points (20%)
 10 Laboratory Experiments: 10 Labs(10 points/Lab) = 100 points (20%)
 2 Quizzes: 2 Quizzes(20 points/Quiz) = 40 points (8%)
 6 Group Exercises/Homework Assignments: 6 HW(10 points/HW) = 60
points (12%)
Total graded* points = 500
*non-extra credit
Grades will be assigned as a percentage of total points possible, as follows:
Percentage
91-100
89-90.9
86-88.9
82-85.9
80-81.9
77-79.9
73-76.9
70-72.9
68-69.9
65-67.9
<65
Grade
A
AB+
B
BC+
C
CD+
D
F
As may be noted from the above, the course is not graded on a Gaussian distribution. I
reserve the right to normalize the grades upward if the class average falls below a C+.
However, the more likely occurrence will be the assigning of additional problems for extra
credit
2
Exams will be a combination of multiple choice, short answer (generally mathematically based),
and fill in the blank. Questions for the examinations will be taken from material covered in lecture
(≥ 90%) and reading assignments (≤ 10%).
Schedule of Tests:
Section I: Physical Properties of Substances; Atomic & Molecular Structure;
Mass Relationships and Stoichiometry – Friday, 10/13
Section II: Solution Chemistry; Behavior of Gases; Reaction Rate & Equilibrium –
Friday, 11/03
Section III: Acids, Bases, and Salts; Nuclear Chemistry (Final Examination) –
Friday, 12/08, 11:30 to 1:30 am, Room 402
Make-up Examinations
Make-up exams will be considered only if you approach me before the
scheduled exam with an exceptional, documentable excuse. Documentation is
mandatory before a make-up examination will be provided. If you miss an exam
and have not notified me beforehand you will receive a zero for that exam.
Due to time constraints, make-up examinations will not be given for poor test
performance.
Excusal from Final
In the event a student has only to pass the final to receive an A for the course, he
or she is excused from taking the final examination. Since the total number of
graded (non-extra credit) points in the course is 500, .91(500) = 455 points are
required for an A. As a passing score for the final is 65, 390 points (455 – 65)
accumulated prior to the final is required to have the examination waived. This
corresponds to 97.5% of graded points (390/400) on all other work. All other
work must be turned in to exercise this option.
Behavior
You are students who have elected to pursue professional careers in the health
sciences. As such, little needs be said concerning behavior. You should be
mindful of creating distractions, as they only impede your fellow students’
chances of success. Please note that questions are never considered a
distraction, but must be limited to the topic at hand. Flagrant disruptive behavior
will result in dismissal from class; failure to depart will result in the loss of 5 points
for every minute the dismissed student remains.
As a courtesy to others, cell phones should be turned off, or switched to vibrate
only in the event an emergency call is anticipated.
Cheating will not be tolerated under any circumstances. My standing policy is to
give a score of 0 for any exam a student is caught cheating on. As each exam is
worth 20%, and the division of letter grades roughly corresponds to 10% of the
total points available, cheating on an exam will cost you no less than 2 letter
grades.
Disabilities
If you are a student with a disability and would like to request an accommodation,
please see me and/or make an appointment with Claudia Angus, Disabilities
Coordinator (527-4262, Office 133H, e-mail:claudia.angus@wwcc.edu) as soon
as possible. Additional information may be found via the following series of links
from the WWCC website: old website  current students  student services 
disability services. All allowances must be approved by the Disabilities
Coordinator.
