Course
Description:
This
is the second semester of a one-year sequence covering general inorganic
chemistry. It is designed primarily for
students entering fields such as chemistry, biology (including pre-medical and
pre-dental programs), physics, pharmacy, and other majors requiring a full year
of inorganic chemistry. This course
assumes a basic understanding of general chemical concepts such as those
covered in a high school chemistry course or CHM 122, completion of the first
semester of college level general chemistry (CHM 165) and familiarity with
algebra. Math 073 (Elementary Algebra II)
or two years of high school algebra and CHM 165 are required
prerequisites to this course.
What
will you learn in this course? You will
learn how to take a systematic approach to solving problems. You will look at the structure of matter at
the atomic level, and study the changes which occur during chemical
reactions. Particular attention will be
focused on a number of different types of chemical reactions (acid-base,
oxidation-reduction, etc.) and a detailed look at equilibrium reactions,
including energy changes during chemical reactions. We will also take a look at the field of
nuclear chemistry and study how changes in the nucleus affect the structure and
energy of the atom. Intermittently throughout our studies we will take time to
focus on subject matter applicable to our daily lives, such as a study of
household chemicals, energy, and environmental issues.
Class
Schedule:
The
class meets Monday,
Wednesday, and Friday 10:10 am - 12:10 pm. Laboratory experiments
will generally be started on Fridays
and completed on Mondays.

The dates of events (i.e., exams) listed above are
subject to change. The instructor will
announce any changes at least one week in advance.
Participation Points:
Active participation in daily class
activities is essential for maximal course performance. Participation points are awarded for engaging
in daily class activities (approximately 1/3
point per day for a total of 15 points for the
semester.) Students must be present in class and
actively participating to receive these points; consequently, failure to
participate and/or any absences will result in an appropriate deduction from
participation points. You are encouraged
to contact me (in person, by phone, or by e-mail before or soon after an
absence) to determine what material was missed.
Pop Quizzes/Assignments:
Pop quizzes could occur
at the beginning of a class period on any given day. These pop quizzes will focus on material that
has recently been covered in class, assigned as reading from the textbook, or
scheduled for laboratory activities on the day of the quiz. To be prepared for pop-quizzes, be certain to
review your notes after each class period, keep up to date on reading and
practice problems, and read the introduction and procedure for all labs before
coming to class.
Throughout the semester, a few graded assignments will
also be given in class. On some
occasions these assignments will need to be completed in class on the day that
they are given, on other occasions they will be due the following class
period. These assignments may pertain to
either lecture or laboratory materials.
Laboratory
Policy:
There
are required laboratory exercises which will be performed throughout the
semester. Due to the physical make-up of
our classroom/lab, it is hazardous to keep excess lab equipment set-up. Therefore, you are required to be present when a laboratory period is scheduled. Students not attending lab may not turn in
the lab report. Lab reports are due one
week following completion of the lab, with a 10% deduction per week for late lab reports. If you must be absent for a lab, you will be
able to make up credit for one lab report during the week of classes prior to
final exams. This is the only form of
make-up credit available. Out of the 130
lab points, 120 points are allocated to successful completion of reports and 10
points are allocated to appropriate lab etiquette – sharing data as required,
following safety guidelines, care for lab equipment, working safely, cleaning
up, etc. Most labs will
extend over two or more days.
Quiz Policy:
Quizzes are structured as group quizzes. Your instructor will assign you to a group
containing 2-4 members. During a quiz,
an initial period of time will be spent discussing the questions as a
group. No writing or calculating can be
done during this group time, but the members should discuss together the
approach which is required to answer the questions. This will be followed by individual quiz
time, when each individual will work independently to complete his/her quiz.
None of the quiz scores will be
dropped. It is expected that you will
take these quizzes at the times scheduled; however, if you must miss a quiz for
reasons of illness or personal emergency, you must call or e-mail the
instructor before the quiz. Under no
circumstances will a makeup quiz be given simply because the student does not
“feel ready.” If you do not
contact the instructor before the quiz period, a score of zero will be recorded. Makeup
quizzes must be taken within one week of the scheduled date or a score of zero
will be recorded for the missed quiz.
Exam Policy:
You must take four unit exams and
the final exam on the dates indicated. None of these scores will be
dropped. It is expected that you will
take these exams at the times scheduled; however, if you must miss an exam for
reasons of illness or personal emergency, it is expected that you will call or
e-mail the instructor before the exam. If
you do not contact the instructor before the exam period, a score of zero will
be recorded. No make-up exams will be allowed. If
you receive approval to be absent for an exam, your final exam percentage will
be used to calculate a make-up score (percentage multiplied by 60 points). You are strongly encouraged to do what is
necessary to be present for all exams in order to avoid this situation.
Bonus points:
Quizzes: If all group members receive at least
a 90% on a given quiz, the group members will be awarded 2 bonus points. Any group member who is absent on the day of
the quiz forfeits his/her right to bonus points for that quiz.
Exams: Each exam will contain some extra questions
for which bonus points will be available.
Bonus points will be awarded for correct answers to these questions and
will be added into your total exam points.
These
are the only forms of extra credit available for this course.
A note on honesty:
Science is a field which often relies on
collaboration. During both the
laboratory and lecture portion of the class, we will often share ideas and data
with each other in order to help clarify what is happening and to more fully
describe an idea or concept. You are
free to discuss your laboratory reports with each other, but the work that is
submitted must be your own. On exams,
you must rely solely on your own knowledge.
All written work must be in your own words – do not copy from a
book, another individual, or any other source.
A first offense of cheating on a laboratory report or exam will result
in a score of zero recorded for the project involved (exam, lab report,
etc.). Any further incidents of cheating
will result in a failing grade for the course.
Examples (for first offenses):

Study Guide
The textbook provides a detailed
description of material covered in this course.
As you daily read portions of the text, focus on the material covered in
the reading objectives (distributed in class).
As you read, select the most important information (i.e., major
concept). After reading, summarize
each major concept in your own words.
Pencil in
hand
Example problems are provided
throughout the text as a means to test your understanding. I suggest working these sample problems on
your own as you read. It will be
crucial for you to complete the sample problems before moving forward. Chemistry builds on itself - understanding
one concept is essential to understanding the next interrelated topic.
You may also want to note the
subject matter that did not readily make sense to you. Use the margins of the text to record your
questions and bring these questions to the next class period.
Class
time
The direction for this course will
be provided primarily during class time.
In order for you to make best use of this time, you will need to be
alert and prepared for class. Remain
involved by asking questions during discussions in order to clarify concepts in
your mind. The pace of the course will
be monitored such that you will have time to record brief notes. You will sometimes need to write more that
what is required to fill in the blanks in the handouts in order to fully
understand the material. Record notes in
your own words as best you can. Soon
after class, re-read or re-write your notes, supplementing them with pertinent
information. This is also an excellent
time to check your understanding and prepare for the upcoming class period.
Working
Problems
Throughout the semester, you will be assigned practice problem sets and asked to work problems in class, in laboratory experiments, on quizzes
