Questions
collected here cover most aspects of
general chemistry and are suitable for
use in examinations, quizzes, homework
sets, and review assignments.
Answers to some questions in JCE QBank
are available to chemistry teachers (but
not students). To find how to get answers,
click the Answers to Questions link at
the right.
We encourage you to contribute more
questions to any of the JCE QBank
collections, or to contribute one or
more entire collections of questions.

These questions
are designed to be used with the WebCT course management system.
They were written by Renee Cole, Sarah Moline, Johanna Wolf, Katy
Barnhard, Barry O’Grady, Vicki Malueg, John Moore, and others.
Questions were chosen to test various misconceptions students
may bring to a first-year course. Each question provides feedback
keyed to each possible answer. The feedback is designed to address
any misconception that would lead a student to choose an incorrect
response. The questions are organized by standard general chemistry
topics, closely related to textbook chapter titles.
Many questions require the use of data tables and images
that are accessible from within the question. These include
molecular structures that can be manipulated in 3-D using
the Chime plugin and QuickTime movies using the Quicktime
plugin.
In order to create individualized assignments and to allow
the same student to do a homework assignment more than
once, the questions have been divided into groups (called “sets”).
All questions with a set are closely related and test the
same skill or understanding of the same concept. For example,
questions in the same set might differ only by substitution
of a different number into a similar problem statement
or substitution of one compound or molecule for another.
For each general chemistry topic there are 5 to 25 sets
of questions. Each set contains 2 to 20 variations, that
is 2 to 20 unique questions. Questions range from those
assessing basic knowledge to many requiring the use of
problem-solving skills. Question formats include multiple
choice, multiple answer, matching, short answer and calculated
types.
Contributions of questions for WebCT or other course-management
systems are welcome at any time. If you find errors or
ambiguities, we would like to hear from you. Send error
reports or contributions of questions to Rachel Bain.
