Course Prerequisites: Math A, Elementary Algebra with a grade of “C” or better.
Recommended: Reading level 5 or 6 Math prerequisite accomplished within the previous
two years.
Textbooks:
Lecture: Introductory Chemistry by Zumdahl and Decoste
7e (ISBN-13: 9780538736374) OR Intro Chemistry:
Chem 2A from the bookstore (a custom bundle including
the ebook version) ISBN 1111523347.
Laboratory: Laboratory Experiments for Introductory
Chemistry by Dan Kimball. Report Packet for F2013.
The lab book and packet can be purchased together at
Office Max 2693 Mt. Vernon Ave. available now.
Homework: Students will need to purchase a key for WebAssign,an internet homework site.
The text offered by the BC bookstore should come bundled with WebAssign. This should,
hopefully mitigate the book cost. [NB: Make sure you get WebAssign. Don’t count on the
book being bundled with the WebAssign key!!] This registration process will require a
course code as well as the purchased access code. The course code for the Monday Lab
section is: bakersfield 2213 9081. The course code for the Wednesday Lab section is
bakersfield 8848 7646.
Other Supplies:
1) Calculator: Students will need a basic scientific calculator with exponential notation (EE
or EXP on most calculators) and logarithm (log). Sharing of calculators will not be
allowed during exams, so be sure to have your own. You will also need a code for OWL
online homework (possibly included with book). USERID to use BC’s personal computer
labs. You will also need to download and print Power Points (or use a laptop during
lectures).
2) Goggles and a combination lock. The goggles must completely enclose the area around
the eyes with no direct access to the eyes.
4) Bring both textbook and lab manual to every lab period. The textbook may assist during
lectures. Printouts of Power Points or laptops will be important during lectures.
Course Description:
Three hours lecture, one hour discussion, and two hours laboratory per week (5 units). It
covers the principles and applications of general college chemistry. It is designed for
liberal arts, physical education and some baccalaureate nursing majors. A “C” or better in
this course (CHEM 2A) or high school chemistry are prerequisites of Chemistry 1A
(General Chemistry. A “B” grade or better in this course or a “C” or better in Chemistry
1A are perquisites for Chemistry 18, Organic Chemistry. This course (CHEM 2A) can be
used as a prerequisite for BIOL 15 (General Physiology) and BIOL 16 (General
Microbiology).
Anticipated Student Learning Outcomes:
At the end of the course the student will be able to:
1. Understand and explain the atomic and molecular basis for the properties of everyday
materials. Explain the periodicity of the various properties of the elements using the
periodic table.
2. Determine the electronic structure of an atom and understand the
theoretical basis for the arrangement of electrons and the basis for the types of formulas or
compounds formed. Explain the formation of cations and anions from the electronic
structure.
3. Determine the nature of chemical bonding of atoms in molecules and ions
using the periodic table.
4. Relate the chemical and physical properties of substances to molecular
structure, chemical bonding, and intermolecular interactions.
5. Understand and explain the states of matter and the transitions matter
undergoes and determine energy required for a particular transition.
6. Understand reactions by identifying reactants and products, recognizing the type of
reaction, balancing the equation for a reaction and making calculations from the equation
for the purpose of identifying the limiting reactant, product produced or reactant required.
7. Understand the concept of equilibrium and how it is applied in a chemical
reaction and in explaining pH or pOH.
8. Able to predict the formula of a simple inorganic compound and to
identify the compound by name using either the Stock or Classical
method. Determine the empirical formula using laboratory data.
9. Identify basic laboratory equipment and know it’s function or use.
10. State a solvable problem, state a hypothesis, and design an experiment to
solve the problem.
11. Understand the concept of oxidation-reduction and be able to apply the activity series
to predict simple single displacement reactions.
12. Be able to recognize/identify chemistry happening in everyday life.
Evaluation:
Homework: Homework will be done on-line using the Webassign system. You must
purchase an Access Code following the instruction on my Webassign web page. You
must register for the course online. Each homework assignment will cover one chapter
and will be due on the day of the Exam covering the material covered in the relevant
chapters. After this time, the homework assignment will not be available on-line.
Lecture Quizzes: After most lectures there will be a short quiz on the lecture material.
You can use your notes including Power Points. The better your notes the better you will
do on these quizzes. I will drop the lowest lecture quiz.
Exams: We will have three 100 pt. exams throughout the term (see schedule) plus a 200
pt. comprehensive final exam.
Lab Work: The student is expected to attend all laboratory sessions, complete all
laboratory experiments and turn in all reports. Labs generally cannot be made up.
However, you may attend another section with the permission of the instructor. A clean
and safe laboratory environment is expected to be maintained at all times. You are
responsible to keep your lab bench clean. If you make a mess in a common area, clean it
up or see me, if it is dangerous. Leaving the lab without cleanup may result in loss of lab
points. You may also lose points for lack of participation in group activities. I will drop
the lowest lab score. In the first week of class, a safety quiz will be administered based
on the safety rules discussed during the lab period. There will be a Lab Final Exam
administered at or near the end of the course.
Pre-laboratory Assignments: You must come prepared for lab with some
understanding of the concepts, procedures and safety precautions for the day. Before lab,
read the entire experiment and work the “prelab assignment” in your lab book as best you
can. Familiarity with the experiment and the prelab questions will increase your
understanding of the lab work and the class. Waiting until class time to look at the lab
may result in not having enough time to finish the lab and/or poor lab reports and lower
lab grades. Failure to work the pre-lab assignment prior to lab will result in the student
being asked to leave the lab for that period and the points for that lab will not be awarded.
Lab Reports and Prelab Exercises: In this class we will use the “Lab Report” section at
the end of each lab exercise or in the separate lab report packet to serve the purpose of
both the lab notebook and the lab report. Work must be neat and orderly with clear-cut
conclusions. All work and calculations should be shown with answers to the correct
number of significant figures with labels or units. Late labs will either lose points or not
be accepted. The prelab and the lab report of the lab should be stapled together (with the
prelab stapled on top) and handed in at the start of the next lab period. Again, you may be
docked points for non-participation in the lab work.

exam score to determine whether to award you the higher grade.
Assistance:
My primary goal is to teach you chemistry and I enjoy helping students one-on-one. If
you are having trouble, please come and see me. Please feel free to make an appointment
(If I am available, I may only need a moment’s notice). You can set up appointments in
person, by phone or by email. The learning center can assist you in math and reading
skills if necessary. The learning center may also have chemistry tutors available.
Special Note: If you have any special concerns or disabilities that could affect your
learning or if you need any special assistance, please see me as soon as possible. Students
with disabilities who believe they may need accommodations in this class are encouraged
to contact Supportive Services in FACE 16 or call them at 395-4334 as soon as possible to
better ensure such accommodations in a timely manner.
Attendance:
Students who attend class regularly will perform better on exams. In addition, state law
requires instructors to maintain attendance records. Because much of the course material
and experience cannot be gleaned from the course books alone, if you are absent for 4
lectures or 2 labs or the equivalent you may be dropped. If you are dropped you still need
to go through the withdrawal process (see below). You are responsible for material
missed or assignments given during absences.
Late assignments:
No homework or lecture quizzes will be accepted late for any reason. No make-ups will
be allowed for these assignments. Late lab reports will lose points or will not be
accepted. Make-up for tests will be made only with prior arrangement and by special
permission of the instructor.
Withdrawal:
See the BC Catalog. If you discontinue the course for ANY reason, please make
an official withdrawal. To withdraw you need to:
1) Check in your lab equipment to the stockroom and take your lock, apron and
goggles.
2) Pay any fees owed for broken or missing equipment.
3) Go to Admissions and Records Office to complete withdrawal or drop
online. Make sure that you do this or you could receive an “F” in the course.
Classroom Etiquette and Rules:
Please be considerate of other classmates. Students who disrupt the class may be asked
to leave. The following class rules will be expected to be followed.
1. No talking in class unless called upon by the instructor. This includes no cell phone
conversations including texting.
2. All language should be respectful to other students and to the instructor.
3. No disruptive behavior during class discussions.
4. All safety rules should be adhered to.
5. No eating or drinking in class unless specifically authorized by the instructor.
6. No listening to music or other electronic media during lecture or labs.
Academic Honesty:
According to the BC Catalog, “Every instructor has the responsibility and authority for
dealing with such instances of cheating and plagiarism as may occur in class. An
instructor who determines that a student has cheated or plagiarized has a range of many
options which may be as severe as giving the student a failing grade for the assignment.
Furthermore, the student may face other penalties as stated in the college’s Student
Conduct Policy. Finally, it must be understood that a student who knowingly aids in
another student’s cheating or plagiarism--e.g. permitting the other student to copy a paper
or examination question--is as guilty as the other of the offense.”
Cheating on exams or plagiarizing work will not be tolerated. However, I do encourage
you to study in groups. You may work in groups on your homework, but I do expect that
all assignments turned in represent your own work. Although it is impossible for me to
monitor how your assignments are completed, I do consider it cheating to copy from
someone else. Photocopies and/or exact wording and format constitutes evidence of
copying from someone else’s paper and may result in loss of points or a zero on the
assignment for both parties. Remember that you are responsible for learning the material
for exams and you will not learn it if you copy your work from others.
Discussion Periods:
The first hour of the lab period is designed to be for discussion. This relates more to lecture
material than lab material. The instructor will answer any questions you may have on
homework assignments. The instructor will assign students in the class to work homeworklike problems and write them on the board. This is a time to practice what you have learned
in lecture and to assist you in homework assignments. Because of scheduling differences with
the various lab sections and how they relate to the lecture schedule, it would be wise to review
lecture material and homework assignments well in advance to discussion periods, even a
week in advance, in order to maximize your efficiency in learning the material.
