Course objectives:
This
course is the second of a two semester sequence and consists of three components
(lecture, laboratory, and workshop), which are integrated to provide a
comprehensive but thorough introduction to the principles of chemistry. The
laboratory component introduces students to common laboratory methods. The
workshop is a peer-led, small group discussion of concepts and problem solving
in general chemistry.

Course guidelines:
All students are expected to
adhere to ethical conduct and standards.
Attendance to class is
required. Attendance in the lecture will be taken randomly several times throughout
the semester.
Prepare for each class by
reading the Chapter sections prior to class.
Prepare for the
workshop by completing the reading and self-test problems in each chapter prior
to the workshop.
Work out recommended homework
exercises as each chapter is completed.
Homework exercises solutions
and exam solutions will be posted in a Blackboard website that will be kept for
the course.

Final Examination will be scheduled during the final exam period (May
19 – May 24)
Assessment tools:
The
final grade is calculated as follows:
Best
two scores of the three in-class examinations* (40%)
Quizzes
– Grade to be added to exams
Final
Exam (35%)
Laboratory
(20%)
Workshop
grade (5%).
* The lowest grade exam will
be dropped. Missing an exam will result in receiving a zero grade for that
particular exam and thus dropping that grade. There will not be any Make-up Exams.
