Minimum Requirements:
College Algebra (MTH 111) and CH 222 with a C or better
Required Materials: -Chemistry: The Molecular Nature of Matter and Change,
7th Ed., Silberberg
-Access Code for Sapling
-Chemistry 223 Laboratory Manual, Bridgid Backus
-Carbonless Lab Notebook
-Non-graphing/non-programmable Scientific Calculator
Optional Materials: -Lab coat
-Personal Safety Goggles
Calculator Policy: Students will be required to use a non-graphing/non-programmable
scientific calculator for quizzes and/or exams. Department approved calculators are: TI 30xa, TI
30X IIs, Casio fx-260, or HP 10s. If a student does not wish to purchase one of these calculators
the department will provide either a Casio fx-260 or TI 30xa for use on exams and/or quizzes.
Attendance and Classroom Decorum: Class attendance is very important to the learning of
chemistry. Students are expected to attend class regularly and on time. Entering the classroom
late or leaving before the class ends is distracting to students and your instructor. There is NO
cell phone use in the classroom allowed. The use of a laptop computer during lecture class is
approved for CH 223 lecture material only.

Homework Problem Sets: To succeed in chemistry, like learning a foreign language, you
should study and practice every day. As material is covered you will find the problems are
easier to work and not as time consuming as if they are attempted just before the due date.
Keep in mind a typical science course takes 3-4 hrs of work per week outside of class for
every credit hour. Refer to the schedule for homework due dates and times. ***No late
homework will be accepted. Solutions to the homework sets will be available after the due
date.
Warm-ups: Lecture sessions (excluding exam days) will begin with a short warm-up (practice
problem) at the beginning of the period. The warm-ups for a chapter will be collected the day
of the chapter exam. If you fail to turn in the warm-ups the day they are due, then you will
not receive credit for the warm-ups. The warm-ups will be worth a total of 40 points. No late
or make-up warm-ups will be given.
Exams: All exams are given in class. Students who have conflicts with exam days due to other
College functions, illness, or family emergencies must contact the instructor prior to the exam.
Documentation of the College function, illness and/or family emergency must be provided to
schedule a make-up exam.
Laboratory Reports: Lab reports are due at the beginning of YOUR next lab session after the
completion of the experiment. Late lab reports receive a 10% per day mark down. One lowest
lab report score is dropped and extra credit is given if all lab reports are turned in (see extra
credit). No make-up labs will be given. Also, if you miss more than three labs or turn in
fewer than five reports you will not receive a passing grade for the course. This is a lab
class and in order to pass the course you must be passing the laboratory component.
Prelab Questions: Be sure to check the syllabus for which lab is assigned for a
particular week. Most lab experiments described in the manual have prelab questions. Many
of these questions are designed to emulate the laboratory experiment that is about to be
performed. By answering these questions BEFORE the lab period students are able to
understand and perform the experiment more effectively. Prelab questions should be done on
separate sheets of paper and are due within the first 5 minutes of the lab period. The prelab
assignments are worth from one to five points of the lab report grade. No late prelabs are
accepted.
Extra Credit: If you turn in ALL of your lab reports, rather than subtracting your lowest lab
score, these points will remain in your score as extra credit.

An incomplete grade (I) may be given at the
discretion of the instructor. However, a
student must have a passing grade at the
time an incomplete is assigned.
Drop/Withdraw Policy: If you are withdrawing from the class you must file a Schedule
Change Form with Registration or use WebRunner. If you formally drop the class by Monday
of the second week of the term, you will receive a tuition refund. If you withdraw after the
Monday of the second week of instruction through the seventh week a ‘W’ will show up on your
transcript. No withdrawals are allowed after the end of the seventh week. An instructor may not
assign a “W” grade.
If you received financial aid or veteran’s benefits PLEASE talk with associates at the appropriate
office to determine what effects on eligibility dropping a course will have. Don’t jeopardize
your eligibility!! You can contact the Financial Aid Office by calling (541) 917-4850 or by
visiting the Financial Aid Office in Takena Hall.
If you stop attending the course without formally withdrawing you will continue to accumulate
grades (zeroes for all assignments not turned in) and will receive the grade assigned by the
instructor. You will also be held accountable for all charges on your account.
Academic Integrity: “An instructor has the right to issue a grade of F for the course in which
the instructor has reason to believe the student has cheated. A student has the right to appeal such
action in accordance with the Students’ Rights, Responsibilities and Conduct Policy.” The
preceding statement is Adminstrative Rule No. 7030-01.
LBCC Comprehensive Statement of Nondiscrimination: LBCC is committed to providing
equal opportunity in all of its programs, policies, procedures, and practices, and the college shall
promote equal opportunity and treatment through application of this policy and other college
efforts designed for that purpose. For further information see Administrative Rule No. 1015-01

Center for Accessibility Resources:
You should meet with your instructor during the first week of class if
 You have a documented disability and need accommodations,
 Your instructor needs to know medical information about you, or
 You need special arrangements in the event of an emergency.
If you believe you may need accommodation services, please contact the Center for Accessibility
Resources (541) 917-4789. If you have documented your disability, remember that you must
make your request for accommodations through the Center for Accessibility Resources Online
Services web page every term in order to receive accommodations.
