Chemistry, Geosciences, and Environmental Science
Chem 108-010 and 030 College Chemistry II Spring 2007
Objectives
This course is a continuation of the first semester College Chemistry course, CHEM 105. Over the semester, we will cover the remainder of the textbook that was used in CHEM 105. Using the material and skills learned in CHEM 105, the following topics will be covered:
1. The nature of solutions and
the factors that affect the solubility of solutes.
2. Chemical Kinetics or the
study of the speed of chemical reactions and the factors that influence how
fast a reaction can proceed.
3. Chemical Equilibrium: The study of chemical reactions in their
equilibrium or most stable states.
4. Chemical
Thermodynamics: The study of energy
flows during chemical reactions and the criteria that are necessary for a
reaction to occur.
5. Descriptive chemistry of
various parts of the periodic table.
6. Electrochemistry: The study of the relationship between
electricity and chemical reactions.
7. An introduction to Organic
Chemistry.
8. Nuclear Chemistry: The study of radioactivity and nuclear
reactions.
9. Coordination Chemistry: The study of a special type of compound that
transition metals form.
Required Materials
·
Textbook: Brown,
·
Lab book: A locally produced lab
book that should be available in the bookstore.
Be sure you get the second semester lab book. Students registered in honors lab do not need
to purchase a lab book.
·
A non-programmable scientific calculator (with trigonometric
functions, etc) will be required for quizzes and exams. The calculator policy will be explained in
further detail later in this syllabus.
Course Procedure
You
will be expected to attend all lectures.
Lectures will be given on a MWF 11 schedule. Regular attendance is an important factor in
doing well in this course. Even missing
one class may put you very far behind in the material. It requires an awful amount of work to catch
up in this course when you fall behind.
In
order to keep you studying at a regular pace, online homework will be assigned
using the PhGradeAssist program. In most
cases, you will be given one assignment per chapter of material. The due date and time of the assignments will
be given at the beginning of each lecture.
The problems will consist of a combination of multiple choice and
numeric problems. If you used the online
homework program last semester, your login ID and password from last semester
should still work on the Course Compass website. You will need to register on the
PhGradeAssist homepage for this class.
If you did not use the online homework last semester, you will need an
access code to set up a login ID and password for the program. There should have been an access code wrapped
up with the textbook if you bought it at the school store last semester. If not, an access code may be purchased
online at the course compass website.
More information about this online homework program will be given out in
the form of a handout during the 1st lecture and will be gone over
during the 1st lecture.
CHEM
108 proceeds at a faster pace than CHEM 105.
It is also assumed that you remember the material from CHEM 105. This course starts off at a fast pace right
at the beginning of the semester and
does not stop. You will need to start
studying starting at the beginning. If
you need help, there are various sources to get help. They include:
1. Your
textbook: I generally follow the
order in which the material is presented in the textbook but from a different
perspective. Reading the textbook may
present you with a different way of looking at the material that may help you
understand the material better.
2. The
Course Compass Website
(www.coursecompass.com) : This
site is generally used as a bridge to get to the PhGrade Assist web page. However, the Course Compass web page also
contains many features to assist you.
There is a math toolkit in the student learning resources that gives you
practice with math skills including the use of logarithms, exponentials, and
significant figures in calculations.
There is a section for each chapter in the book with practice problems
for you to solve.
3. Your
professor: Dr. Arthur A. Low,
Office: Room 417,
4. My
website at Tarleton (www.tarleton.edu/~alow)
At the homepage of this website are links to all the courses that I teach at
Tarleton. If you click on the link to
the CHEM 108 Spring 2006 page, you will find a course description with links to
the syllabus, lecture notes for each chapter, and keys to exams given last
year. There are also links to CHEM 108
classes given in previous semesters with more information that you might find
useful.
5. Supplemental
Instruction: An SI leader will be
assigned to this lecture. He or she will
sit in on the class and schedule a number of help sessions per week. Please attend these sessions regularly, not
just before a test. Usually the session
just before a test is the least useful because the room is crowded with
students wanting to know all the information in a very short amount of time.
6. Tutors: There should be lists of tutors available in
the departmental office (room 117) and the Teaching and
In
addition to the assigned homework, I have chosen a number of the problems from
the end of the chapter that I think you should know how to solve. The list of these problems is in the
tentative schedule at the end of this syllabus.
Please try to do these problems on your own. The answers to these problems will be linked
to the course syllabus on my website.
Grade Evaluation
Your
grade in this course is evaluated on the basis of your performance in lecture,
lab, and the final exam. You will be
given a grade for each part. Your course
grade is a weighted average of these three grades with the lecture grade
counting 50%, the lab grade counting 25%, and the final exam grade counting 25%. An easy way to calculate the course grade is
to take two times your lecture grade, add your lab grade and your final grade,
then divide the sum by 4. For example,
if a students lecture grade was 75, the lab grade was 85 and the final exam
grade was 77, then the course grade would be equal to 80.3 as shown below:
Letter grades are assigned as
follows based on your course grade:
90-100: A; 80s B; 70s C; 60s
D; below 60 F. Because this is a lab
science, you may not pass this course without passing both the lecture and
lab portions of this course separately. Your lab grade needs to be
above a 60 and your lecture grade needs to be above a 60 in order to pass this
course. Your lecture grade may include
the final exam, if necessary (if your lecture grade is below a 60, you may
still pass if you pass the final exam).
Your lecture grade is
calculated based on your performance on the 4 exams given in class and your
homework average. The lecture grade is
calculated by averaging your 4 exam grades plus two times your homework
average. The exam grades are curved
grades on each exam based on your actual score on each exam. The homework average is the average of your
10 highest assigned homework grades.
During the semester, I may give an attendance quiz which will give you
an additional homework grade of 100 for just being in class. Attendance quizzes are given at the discretion
of the professor.
There are 4 exams
scheduled during the semester for:
Wednesday, Jan. 31; Monday, Feb. 26; Monday, Mar. 26; and Monday, Apr.
23. These exams consist of 10 multiple
choice questions worth 4 points each for 40 points and 5 numerical problems
consisting of 3 10-point problems and 2 15-point problems for a 60 points for a
total of 100 points. You will be given a
raw score for each exam on the test.
Each exam is curved to a certain extent and the curve will be given to
you in terms of a grade range for the scores.
For example, on a certain test a grade of 87 up to 100 is an A; 74 up
to 86 is a B; 60-73 is a C; 46-60 is a D; and below 46 is an F. Your curved grade will depend on where your
grade lies in the range given. For
example, in the curve above, a grade of 70 on your exam would be curved to a
grade of 76. Again, the curved grades
are the grades used to calculate your lecture average.
The final exam for this
course will be given during the Freshman chemistry slot on Saturday, Apr. 28 at
11:30 AM. It consists of two parts. The first part is a national exam written by
the American Chemical Society that covers the entire year of college chemistry,
both CHEM105 and CHEM108. It consists of
50 multiple choice questions and you will have a maximum of 55 minutes to
finish it. It will be graded by scantron
(green sheets). The second part is an
exam written by me that covers only CHEM108.
It will be assembled using questions given on exams given in class. It will consist of 10 multiple choice
questions and 5 problems just like a class exam. The final exam grade will be a weighted
average of your grades on the two parts with the national exam counting 40% and
the second exam counting 60%
Makeups
Makeups will be given for exams only. Makeups will be given during the week after
the exam was scheduled. The makeup exam
will cover the same material but will consist of different questions. It is up to the student to arrange a time and
place to take the makeup exam. The
arrangements must be made with me in person or over the phone.
Calculator policy
It is the departmental policy that programmable and graphing calculators will not be allowed for use for quizzes and exams in all College Chemistry courses. You will be allowed only a non-programmable scientific calculator (one with trigonometric functions, logarithms, square roots, etc.). You can obtain a simple scientific calculator for $10.00 or less nowadays. Violations of this rule will be treated as an act of academic dishonesty.
Cellphones
All cellphones, pagers, etc. need to set to silent vibrate in class. The ringing of cellphones and pagers is very disruptive both to me and to the other students in the class. If you need to be contacted by someone during lecture, please set your cellphone to silent vibrate during lecture. If someone calls you, please leave the class, answer the phone, and then return when you are done.
