Course Objectives:
The objectives of this course are to present the fundamental principles of chemistry
upon which subsequent course work is built. Basic topics include, but are not
limited to, atomic and molecular structure, the periodic table and periodicity,
chemical stoichiometry, reactions (precipitation, acid-base, and redox),
thermodynamics, and properties of gases, liquids, and solids. Laboratory
experiments are designed to support the lecture topics.
Textbook:
“Chemistry”, by Brady and Senese, 4th Ed. Required of all students.
Problem Book:
“Chemical Problem Solving Using Dimensional Analysis”, by R. Nakon.
Required of all students.
Laboratory Text:
“Laboratory Experiments for General Chemistry 115", by WVU Staff, 2nd Ed.
Required of all students. Because of the use of fill-in blanks and graphs in the book,
each student MUST have a new copy.
Calculators:
Only non-programmable calculators may be used during quizzes and exams.
Scientific calculators ($8-$12) that perform all the needed mathematical
calculations (including logarithms) are available at the University Book Store as
well as at various commercial establishments. Programmable calculators will be
confiscated at the examination site or the student will not be allowed to take the
exam.
Seating:
Each student will be assigned a particular seat in the lecture room. Attendance will
be checked each lecture. Seating assignments will be posted on the website by the
end of the second week of classes.
Attendance Policy:
Attendance will be used in determining each student’s final grade as shown below.
There are no “excused absences”, although minor adjustments may be made for
personal emergencies. Good attendance (2 or fewer absences) will be rewarded
by addition of 1% to the final numerical average.

In place of quizzes, there will be graded online homeworks (up to three assignments
per chapter). It is your responsibility to complete the homeworks by the given
deadlines. In general you will have three attempts at each question. The online
homework can be found at the following website address:
http://edugen.wiley.com/edugen/class/cls21918 for 115-001
Before you can access this homework, you must self-register (click the register button on the website). Be sure to register for the
correct section of Chem 115. To register, you will need the WileyPLUS REGISTRATION CODE. You should have obtained this
code when you purchased your Brady and Senese textbook package. A registration tutorial can be found at
http://www.wiley.com/college/twomin/stu/register.html
Hourly Exams
Hourly exams will be given outside of lecture. The schedule for exams is as
follows:
Thur., Feb. 1
Exam #1 (7-8 PM)
Thur., Feb. 22
Exam #2 (7-8 PM)
Thur., March 15
Exam #3 (7-8 PM)
Thur., April 19
Exam #4 (7-8 PM)
Wed., April 25
Lab Final Exam (In Lab)
Tue., May 1
Final Exam (7-9 PM)
Students are expected not to register for a class that will conflict with these exam times.
Cell phones are not permitted during exams/quizzes. Covers should be removed from nonprogrammable calculators before entering the exam/quiz site.
Final Exam:
A comprehensive final exam on the material covered in Chemistry 115 is
scheduled for Tuesday, May 1 from 7:00 PM-9:00 PM.
ANY STUDENT SCORING 40% OR BELOW ON THE FINAL EXAMINATION WILL EARN A GRADE OF “F”,
REGARDLESS OF HIS/HER OTHER AVERAGES. SIMILARLY, OTHER VERY LOW SCORES COULD RESULT IN A
REDUCTION OF ONE LETTER GRADE.
This final exam will be comprehensive and cumulative covering the entire course. Due attention will
be given to the cumulative nature of the learning process with emphasis being placed on major topics and
concepts. Your study during the semester should be designed for comprehensive and long-term retention of
the factual material, principles, and use of these. “Cramming” for individual exams largely defeats the
purpose of a college education.
Laboratory
Final Exam:
A comprehensive laboratory final examination will also be given during the last
laboratory period on Wednesday, April 25. Additional details will be provided at
a later date.
Make-Ups:
Make-up exams and labs will only be given for students with legitimate absences
(university business, serious illness, medical emergencies and family emergencies).
A documented excuse must accompany all requests for make-ups. The instructor
should be informed of the absence as soon as possible. Prior knowledge especially
in the case of absences due to university business is appreciated.
Calculation
of Grade:
My object is to give you the best possible grade which can be justified by your
achievement in the course. Final numerical averages will be calculated as shown
below:
Hourly Exams (4)
40% (10% each)
Online Hmwk. Avg.
10%
Lab Avg.
25%
Final Exam
25%
The Laboratory Average is calculated as follows:
Unknown Average
65%
Lab Final Exam
25%
Lab Hmwk & TA Eval. 10%
(Lowest unknown grade dropped.)
NOTE: The lowest unknown grade from a completed lab will be dropped. A zero due to an absence from lab will
not be dropped. There is only one scheduled make-up laboratory.
While individual exams and quizzes may vary in relative difficulty, experience with my classes in
the past has shown that final numerical averages in the sixty range will earn a student a grade of “D”,
averages in the seventy range will earn a “C”, averages in the eighty range will earn a “B” and averages
above ninety will earn a grade of “A”.
In general, the hourly exam average is the best indicator of your performance. In order to determine
how you are doing in the class at any given time, calculate your hourly exam average and compare it to the
class average. If your hourly exam average is much higher than the class average, you are doing “A” or “B”
work. If your average is close to the class average, you are doing “C” work. If your average is well below
the class average, you are doing “D” or “F” work.
Problems and At the end of each chapter in the text and in the problem book are numerous questions and
Questions:
problems. Specific problems related to the material covered in lecture will be assigned as
other homework. Although these problem assignments will not be collected and graded, they should help
you understand the various concepts in lecture and thereby prepare you for the examinations. Answers
to many of these problems can be found in the back of your textbook and problem book.
West Virginia University is committed to social justice. I concur with that commitment and expect to foster a nurturing
learning environment based upon open communication, mutual respect, and non-discrimination. Our University does
not discriminate on the basis of race, sex, age, disability, veteran status, religion, sexual orientation, color or national
origin. Any suggestions as to how to further such a positive and open environment in this class will be appreciated and
given serious consideration.
If you are a person with a disability and anticipate needing any type of accommodation in order to participate in this
class, please advise me and make appropriate arrangements with Disability Services (293-6700).
West Virginia University recognizes the diversity of its students, many of whom must be absent from class to participate
in religious observances. Students must notify their instructors by the end of the third class meeting regarding religious
observances that will affect attendance. Further, students must abide by the attendance policy of their instructors as
stated on their syllabi. Faculty will make reasonable accommodation for tests or field trips that a student misses as a
result of religious observance.

YOU DROP THE COURSE, YOU MUST CHECK-OUT OF YOUR LABORATORY DESK.
Laboratory Conduct: There is no smoking in the building. Each student is to do his/her own work
in a quiet, efficient manner. The work area is to be kept clean and orderly. At the end of the
laboratory period, the work area/sink should be clean and all common equipment should be returned
to the common equipment container. The gas jets should be checked to ensure that they have been
turned off. The student should inspect the desk area to ensure that no apparatus has been left out.
Laboratory Safety: Read the safety regulations carefully and adhere to them rigorously at all times
for your own well-being and that of your fellow students. YOU MUST WEAR SAFETY
GOGGLES (NOT SUNGLASSES OR CONTACTS) WHENEVER YOU ARE IN THE
LABORATORY. Covered shoes (not sandals, clogs, or open shoes) are to be worn at all times
in the laboratory. Long pants or long skirts are to be worn instead of shorts. Old jeans, a Tshirt, and sneakers are the best laboratory attire. Portable radios, walkman, etc. are prohibited in the
laboratory. NO FOOD OR DRINK IS PERMITTED IN THE LABORATORY.
Laboratory Absences: Students should attend all laboratory sessions. Students absent because of
severe illness or university business will be given a make up lab at the end of the semester. A
documented excuse is required to make up a lab. This excuse should be given to the instructor
in charge and not to the TA.
Preliminary Work: Before coming to the laboratory, you should read through the experiment
carefully. Make a list of all precautions to be observed and plan the best way to do the experiment
beforehand.
Desk Locks: You will be given a combination lock for your desk. You are responsible for the
equipment in your desk. It is your responsibility to open and lock your own desk.
Unknowns: Only one attempt will be allowed for each unknown. Check any calculations carefully
before you hand in your result. These results should be handed in at the end of the period. If you
have not completed the experiment, notify your teaching assistant.
