lecture. Discussion sections and labs will meet starting the week of Sept. 9. For discussion
sections, please bring a calculator. For lab, please bring safety goggles and a lab notebook and
dress appropriately (closed-toe shoes, long pants or skirt, and a shirt that covers your midriff).
Required Materials
Text: Brown, LeMay, Bursten, Murphy, Woodward, Chemistry: The Central Science, 12th
edition. This text is available in the college bookstore. You may also purchase an electronic
version of the text at www.mypearsonstore.com. If you buy a new copy of the text in the college
bookstore, it comes with access to the “Mastering Chemistry” website, which provides additional
problems and learning materials to accompany the text, and a student solution manual, which has
solutions to problems with answers in the text as well as an explanation of the solution. You can
buy a used text and purchase access to “Mastering Chemistry” and/or the student solution
manual separately if you desire. Neither access to the “Mastering Chemistry” website or the
student solution manual is required.
Safety Goggles: These must be worn at all times in the laboratory. Goggles will be available
for you to use but you are encouraged to purchase your own (they should be available in the
college bookstore).

Laboratory Notebook: This is a bound duplicate notebook with numbered pages; it can be
purchased in the college bookstore.
Calculator: This must have log and exponential capabilities.
General Information
Student Learning Outcomes
By the end of this course, students will be able to:
1. Apply the concepts of uncertainty and dimensional analysis to solve chemical problems.
2. Understand the relationship between atoms, molecules, and moles and be able to apply this
idea to chemical equations
3. Understand the atomic basis for the periodic table and the trends in atomic properties that
exist in the table.
4. Identify and describe the subatomic particles (electron, proton, neutron) and understand how
they fit into the picture of the atom. Students will be able to describe how chemist’s
understanding of these particles has changed with the development of quantum mechanics
and be able to apply this knowledge to solving problems involving small particles.
5. Identify the type of aqueous reaction that is likely to occur between two reactants
(precipitation, oxidation-reduction, or acid-base) and predict the products that will form.
6. Use thermodynamics to predict the energy and/or temperature change in a given chemical
reaction or phase change.
7. Apply the gas laws to solve a variety of chemical problems.
8. Predict the three dimensional and bonding structures of molecules. Moreover, students will
understand how these structures affect various properties and the reactivity of the molecules.
9. Apply the scientific method to their own experiments, be proficient in fundamental
laboratory techniques, be able to record relevant laboratory data and observations, be able to
analyze their experimental results, and be able to accurately summarize and convey these
results to others.
Course Strategy
Reading the text (skim it before the lecture and then read it thoroughly after the lecture),
doing all the assigned homework, and coming to class are essential for succeeding in this course.
Doing extra problems is especially helpful. The text has a website (Mastering Chemistry) with
some self-study resources. If you purchase a new text, you should receive an access code for this
site. If you purchase a used text, you can purchase access to this site (~ $40) at
www.mypeasrsonstore.com. I encourage you to form study groups and I can help get these
groups together and/or can suggest problems to work on. Don’t be afraid to ask questions—there
are no stupid questions and I guarantee that someone else has the same questions. In addition to
helping you, your questions will help me by making me aware of difficulties that the class is
having with the material. Don’t hesitate to see me if you’re having difficulties!
Lectures
It is important to read your textbook before coming to class or at least skim it over to get
a sense what we will be covering. Use the syllabus to find out what will be covered in lecture
3
and read ahead. After class read the chapter and try some of the problems to practice what you
learned that day. If you don’t understand something, ask questions during lecture or come see
me after class or during my office hours.
Office Hours
If you have questions that cannot be answered in class, would like additional practice
problems, would like to talk about the class, or would like to talk about chemistry in general,
please see me during my office hours. If the posted times don’t work for you, feel free to make
an appointment with me for another time or talk to the other General Chemistry professor (Louis
Kuo) as appropriate.
Discussion Sections
These sections give you the opportunity to practice what you’ve been learning in lecture
and to challenge your comprehension of the material. You must register for a discussion and
show up. Students will work in assigned groups to complete a set of problems with help from
your group members as well as your instructor. For discussion section, please bring your
textbook and calculator.
Laboratory
The lab is an integral part of the course. This is when you get to put into practice what
you’ve been learning. Plan on attending all your labs as there are no make-ups. Scheduling
conflicts due to athletics or illness must be worked out with your lab instructor as soon as
possible, preferably before the lab that will be missed. Read the lab before you arrive! Doing so
will likely give you greater experimental success and help you to finish faster. In order to pass
the course, you must pass the laboratory section of the class!
Moodle
The class moodle page will feature copies of assignments and solutions to homework and
discussion problems and practice tests. There will also be links to other sites that you may find
interesting as well as class announcements. To access our course Moodle page directly, go to
http://moodle.lclark.edu. You'll be prompted to login to Moodle - use your L&C login and
password (same as for email). Scroll down in the list until you find the chemistry department,
click this link and then click on our course/section. Remember, we’re section 1. You'll be asked
to type in the enrollment key for this Moodle page, which is CHEM110_01. Remember,
enrollment keys are case sensitive. Please let me know if you have any difficulty accessing the
page.
Academic Honesty
I expect academic honesty. This means homework, labs, and exams should be your own
efforts. Discussion about homework assignments and labs is encouraged but the work you turn
in should be your own (i.e., it should be in your own words and you should be able to explain it
fully if asked). You will be assigned a clicker to use during lecture; do not use another student’s
clicker and/or take the clicker for a student who is not in class. Cheating will result in failure on
the assignment, possible failure of the course, and disciplinary action by the College Honor
Board. Please consult the Pathfinder for more information on the College’s academic integrity
policy. If you are having problems come see me!
Classroom Disruption
I expect the classroom to be a comfortable environment for learning and that we support
each other as we cover the basics of chemistry. Thus, disruptive class behavior, which is
4
behavior that in my judgment impedes another student’s opportunity to learn or interferes with
the class goals, is unacceptable. Should such behavior occur, the student will be asked to leave
class and I will refer the matter to the director of Academic Advising. Permission to return to
class will be granted only after the student meets with the director of Academic Advising and
agrees to stop the disruptive behavior. If the disruptive behavior continues, the student will be
dropped from the course.
Academic Accommodations
If you have a disability that may impact your academic performance, you may request
accommodations by submitting documentation to the Student Support Services Office in Albany
Quadrangle (x7191). That office will notify me of the accommodations for which you are
eligible.
Grading
3 “Midterm” Exams 45%
Final 20%
Homework 10%
Discussions 2.5%
In-class activities 2.5%
Laboratory 20%
Midterm Exams
Three one hour midterms will be given in class. The dates for these tests are in the syllabus.
Final Exam
Your final exam is scheduled for Monday, Dec. 16, 1 – 4 pm.
Homework
Homework will be assigned weekly and will be due at the start of class each Friday. To be fair
to students who hand their homework in at the start of class, papers handed in right after class or
later in the day will be accepted with a 5% penalty. Students get one “free pass” (i.e., no
penalty) for homework that is less than one day late. Late homework will be accepted up to one
week past the due date; homework that is more than one day late will be penalized by 10%. The
lowest homework score will be dropped.
Discussions
Students will work in assigned groups during their discussion section. We will change groups
mid-way through the semester. Each group should work their way through the problems
provided. Solutions will be available during the discussion so that you can check your answers
and make sure that you understand the material. Your discussion grade will be based on
attendance and participation. If you are late to discussion or leave early (unless you show the
instructor that your group has completed all the problems), your grade will be the percentage of
the class hour; thus, if you are 10 minutes late, your grade for that discussion will be 83%. We
also expect you to participate in discussion; this means that you shouldn’t use the time to do
homework or study for other classes, text, etc. Your two lowest discussion grades will be
5
dropped. Since we are dropping the lowest two grades, unless there are extenuating
circumstances, absences will count as a 0 (and the grade will presumably be dropped)
In-class activities
Throughout the semester we will have in-class activities of primarily two types: clicker
responses and problem-solving based on lecture/reading/viewing material. These activities are
intended to encourage you to think about the lecture material during the lecture, to give me a
sense for how well the class is learning the material, and to keep track of attendance. Students
will receive a score of 100 (for trying) or 0 (for being absent or failing to respond the
assignment).
Your lowest two in-class activity grades will be dropped. Since we are dropping the lowest two
grades, unless there are extenuating circumstances, absences will count as a 0 (and the grade will
presumably be dropped).
Laboratory
Your lab instructor will discuss how to prepare your lab reports and how these will be graded.
In order to pass the course, you must pass the laboratory section of the class!
