Chemistry is all around us. Chemical reactions are constantly occurring in our everyday life.
With each breath we take, a chemical reaction occurs. When we eat carbohydrates what reaction
occurs? How does an antacid tablet work? What reaction occurs when an air bag inflates in a car
accident? Did you ever wonder why fireworks are so colorful? Or why hot air balloons rise?
Why are more homeruns hit in stadiums at high altitudes? What is the geometric shape of a water
molecule or the carbon dioxide molecules that we exhale? Why is chemistry considered the
central science? The answers to these questions and others can be found in Chemistry 120. I hope
you will join me in discovering the chemistry that surrounds us.
Course Description: Chemistry 120 at KVCC is an introductory college chemistry course.
Topics include measurement, chemical terminology, stoichiometry, atomic
theory, chemical bonding, geometry, the periodic table, gases, molarity, and
thermochemistry. Mathematical relationships in chemistry are emphasized.
Class Format:
Topics will be presented in a lecture-discussion format with questions from
the instructor and also from the students. Class participation by students is
expected. Laboratory time will involve pre-experiment discussions and
performance of experiments and/ or exercises. Lab work is designed to
demonstrate concepts presented in class. To successfully complete this
course, attendance is necessary in lecture and lab.
Student Conduct:
Treat others with respect. Be prepared for class and actively participate.
Dress appropriately for lab. Turn cell phones off prior to class.
Academic Honesty:
KVCC’s policies regarding cheating, academic dishonesty, plagiarism, and
fabrication will be upheld as stated in the Student Handbook under Student
Rights and Responsibilities.

Testing Policy: If an emergency situation occurs that prevents a student from taking a test, the
instructor must be contacted preferably prior to the test (or within 24 hours of the
scheduled test). Makeup exams are at the discretion of the instructor. Failure to
contact the instructor will result in a zero for the test.
Assessments: Assessment of your performance in this class will include quizzes, exams, and
laboratory work. No make-ups are allowed for laboratory experiments/exercises or
lecture quizzes. As a result, if you are absent, you are allowed to drop one
laboratory score and one lecture quiz score from your total course points.
Makeup exams are at the discretion of the instructor. (See Testing Policy above)

OWL web site: Online required homework assignments will be accessed through OWL (Online
Web-based Learning) at www.cengage.com/owl . In addition to required homework assignments,
helpful tutorials and simulations are at this site. Please see the attached OWL Student Guide for
more information.
Laboratory Web Site: All experiments and lab procedures will be accessed through the web site
http://classes.kvcc.edu/chm120. Prior to each lab session, the student must read the pre-lab and
lab experiment at this website.
The score for each lab experiment consists of 30 points for the OWL homework assignments and
70 points for the laboratory assignment. The scores from the 11 experiments are averaged to
contribute 100 points to the total course points. You may miss one experiment without a penalty,
however the second absence results in a zero for that experiment. The third absence from lab
results in a zero for the missed experiment and an additional 10 % reduction of your course grade.
Laboratory Safety Rules: Safety glasses must be worn while cleaning glassware, working with
chemicals, and performing experiments (at all times in the lab).
Sandals and open toe shoes are not allowed in the lab. Shoes must cover the entire foot.
Dress appropriately for lab.
Beverages and food may not be consumed in the lab.

Answer Formatting in OWL
As with most online homework systems, when you answer questions in OWL, your
responses must be correctly formatted in order to be graded. For some answers, you
must enter superscripts and subscripts in your answer. Proper answer formatting is
especially important when entering chemical formulas, mathematical equations, and
units of measurement. Improper formatting will lead to otherwise correct answers
being marked wrong. Be sure to complete the Intro to OWL assignments to learn the basics of
answer formatting and setting up your browser correctly.
