The laboratories are located in the Frost Chemistry Building, 1st floor. You will have
laboratories and tutorials in alternate weeks. The tutorials will be held in room GA30. Note
that the morning tutorial sessions begin at 9:00 am, the afternoon sessions at 2:30 pm.
The program begins with WHMIS safety training in weeks two and three. I will post a tutorial
and laboratory schedule on the WEB.
Required Materials
Text:
Steven S.Zumdahl, Chemical Principles, ( 3rd Edition, Houghton Mifflin, 1998)
is the primary text and all text references in lectures will be keyed to this book and
some problems will be drawn from it.
Last year, we used D.W. Oxtoby and N.H. Nachtrieb, Principles of Modern
Chemistry, 3rd ed., and many used copies may be available. This book is similar
in level and content to Zumdahl and some students may wish to use it. However,
they are then responsible for finding the references from lectures and getting
problems from Zumdahl.
Laboratory:
The laboratory manual is available through the laboratory and the laboratory
notebook and safety goggles are available from the Campus Bookstore.
Refer to the laboratory manual for all the safety regulations that must be
followed in the laboratory.
Resources on the Web site. WWW.CHEM.QUEENSU.CA
Many different forms of course material can be found on the chemistry World Wide Web
site. This will include outlines of some of the lectures, solutions to assigned problem sets, and
copies of old midterm and final exams. QChem, a thermochemical database is available on the
file server also, ftp.ccs.queensu.ca. QChem provides tables of thermochemical data together with
utilities for the calculation of the Molar Mass of compounds and for calculations and graphical
representations involving both the ideal gas relation and the van der Waals and Redlich-Kwong
equations of state for real gases. Other information will be made available as the term proceeds.

REGULATIONS
Completion of the experiments, reports and laboratory assignments is mandatory. Failure
to complete an assignment without an acceptable documented reason (illness, compassionate
leave) will result in a grade of zero for that assignment. Failure to complete a satisfactory
amount of the laboratory work will result in a maximum grade of 45% in the course.
Students who believe they have satisfactorily completed the equivalent of the laboratory
program in a course at Queen’s or another post-secondary institution can apply for a laboratory
exemption. Forms for this purpose are available from the instructor. It will be the applicant’s
responsibility to confirm that an exemption has been granted. Such exemptions apply only to the
laboratory part of the program; the candidates are expected to complete all other assignments and
examinations in the course. If an exemption is granted, the mark in Chem 120 will be
determined solely by the student’s performance on the assigned problems, Midterm and Final
Examinations.
Laboratory experiments are to be conducted only under supervision and in the assigned
laboratory period. The laboratory record book is to be kept up to date and completed during the
laboratory session. The usual writeup will record the data collected during the experiment, the
calculations and the final results and the answers to specific questions in the laboratory manual.
Laboratory record books are to be deposited with the demonstrator at the end of each laboratory
session and will be returned to the student at the beginning of the next laboratory session. For
one of the laboratory experiments an extended formal report will be required.
The scheduled tutorial/discussion periods will be devoted to working practical examples
of the type likely to appear on tests and exams, and answering questions about the course
material. Attendance is not compulsory, but is highly recommended for all students. Students
will have laboratory and tutorial sessions scheduled on alternate weeks in the first part of the
term and offset later in the term. Tutorial sessions will be 1 to 1 ½ hours in length.
Working many problems is the best way to test and solidify your mastery of the course
material. In addition to assigned problem sets and tutorial work, students should attempt a good
selection of the problems in the text (checking answers in the Solutions Manual) and from old
tests and exams (available on the file server).
Engineering students may also wish to take advantage of the Douglas Tutorials, a
program in which senior year students are made available to tutor 1st year students.
LECTURE MATERIAL
The course material is divided into two units, each unit handled by one instructor. Towards the
