An alert state of mind will be most helpful.
A sense of humor will be appreciated by everyone.
PLEASE TURN OFF YOUR CELLULAR PHONES AND
PAGERS DURING CLASS. You may not check email,
text or surf on the net during lecture.
Expectations:
Students are expected to attend every class.
If you are absent from class, regardless of the reason, you will be
responsible for the material covered. However, there will be no make
up participation activities, or in class quizzes.
Disability Resource Center - If you have a documented disability that may
require assistance, you will need to contact DRC for coordination in your
academic accommodations. DRC is located in the Reynolds Student
Services Complex, Suite 137. The phone number is 702 895-0866 or
TDD 702 895-0652. You may also visit their web site at:
http://studentlife.unlv.edu/disability/
Class participation and questions will be welcome. However, please be
courteous and respectful of others during discussions and question /
answer sessions. Inappropriate or rude behavior will not be tolerated.
This includes texting or surfing the net.
Policy:
This course will be composed of lectures, online exercises, homework and quizzes
assigned through SaplingLearning, in class activities, three – semester exams,
and a final exam. See the tentative class calendar.
Generally, quizzes will cover the concepts discussed in class. There will be no makeup quizzes given. The highest ten quiz scores out of 12 quizzes will be used
when computing quiz averages, and normalized to 100%, potentially contributing
up to 100 points earned toward your semester point total.
Each of the three semester exams [100 points each] may be a mix of multiple choice and
work problem questions. There will be no make-up exams.
The exam scores and quiz average will contribute up to 400 points [approx. 61.6%]
toward your point total.
Final Exam Scores Percentages will be used to replace a missed exam or the lowest
exam score if greater that the one lowest score. For example: Score of 120 /150
80% 80 points used to replace a zero or one score lower than 80.
Points earned for exercises and homework assignments on the SaplingLearning website,
and any in class activities and homework assignments submitted in class will be
totaled and normalized to 100 points [15.4%] and contribute up to 100 points
toward your total points earned for the semester.
Example:
Total 260 possible points for Homework.
You accumulate 230 points
(230/260) x 100% = 88.46 points toward your final point total
The topics covered in this course form the foundation for future topics. Thus all of the
material is cumulative and each exam may have questions for which you will need
to draw upon information covered by previous chapters or exams. The final exam
will be worth up to 150 points or 23% and will be cumulative, covering the entire
course. You must take the final exam to pass this course.
Your Final Course Grade will be a letter grade (no S/F grade). Your final grade
will be based upon [total points earned, 650. Mid Semester grade
estimates will be based upon percentages. The following grading scale
will be used as a starting point to assign letter grades. The grading scale
will never be raised but at my discretion may be lowered (to the
advantage of the class) at the end of the semester.
Grade
Total Points / %

The “15 minute rule” will prevail. If for any reason your instructor cannot make
a class or appointment and you have waited 15 minutes, then you may
assume that the class or appointment has been cancelled and will be
rescheduled at a later time.
You must register in the WebCampus part of the class, because lecture
presentations, announcements and discussions will be posted on the
site. Registering for WebCampus will be covered during the first and
second class of the semester.
You must also register in the SaplingLearning online program at the following
web address: http2://www.saplinglearning.com/
Cellular phones and pagers must be turned to OFF or SILENT while in class.
Tips for Success:
Attend ALL lectures. Take all quizzes and exams.
KEEP UP with the concepts presented in class. Study as often as possible. A
typical rule of thumb is to devote at least two hours of study for each hour
of lecture. CHEMISTRY IS CUMULATIVE! Don’t be afraid to ask for
help. It is available for the asking. Get help ASAP, do not wait until a day
or two before an exam to ask for help. Help may not be available at that
time.
The purpose of the online problems and homework is to allow you to practice
the kinds of questions that will help you gauge your understanding of the
concepts covered in lecture. The assigned problems are the minimum
number of problems that you should work in order to master the course
concepts. You may find that some exam questions may be similar to
these problems while some questions will be worded differently, although
cover the same topics and concepts.
If possible, study with others outside of class. Form a study group. Working
with others can be very helpful if each member of the group takes a turn
to explain a concept.
You may find studying with a tutor to be helpful. One on one attention may
work better for you than working with a group. You can meet with me and
possibly tutors at the Chemistry Department Learning Center in CHE 224
(recently moved)
You can also contact the Center for Academic Enrichment and Outreach in the
Reynolds Student Services Complex (895-4777), or at their homepage:
http://caeo.unlv.edu/tutoring.html for information regarding tutors.
Supplemental Instruction will be available through the Academic Success
Center. More information to follow.
Academic Dishonesty:
Cheating will not be tolerated in this course.
http://studentconduct.unlv.edu/.
Lecture:
As stated above, attendance at lectures is essential and expected. You are
responsible for all announcements and concepts covered in lecture
including information not covered in the textbook or lecture notes, but
presented during class lectures. . To get the most out of lecture, read the
chapters and/or suggested pages in your text before coming to lecture.
There may be pre-lecture quizzes. Study tip: After lecture, read the text
again along with your notes and work the relevant end of chapter problems.
Office Hours: Any time office door is open.
The days and times of office hours are posted on my office door schedule.
Although a recitation section is not officially scheduled, you may consider
office hours to be a recitation section. Office hours are for your benefit. It is
a time where you can seek help, discuss concepts, develop better
understanding of topics. In addition to posted office hours, stop by my office
and if the door is open, ask if I am available for questions.

Chemistry is the study of substances in terms of:
• composition
• structure
• properties
• reactions
What is it made of?
How is it put together?
What characteristics does it have?
How does it behave with
other substances?
Branches of Chemistry
The field of chemistry is divided into branches
such as
•general chemistry
•organic chemistry
•biochemistry
•geochemistry
•physical chemistry
•analytical chemistry
•environmental chemistry
What are stubstances made of?
Matter.
Matter is anything that has mass and takes up
space.
Matter has both physical and chemical properties
Physical properties are:
Characteristics observed or measured without changing the identity of
a substance.
Shape, physical state, odor, boiling and freezing points, density, and
color of that substance.
Chemical properties describe the ability of a substance
To interact with other substances, and/or
To change into a new substance.
Physical Properties of Copper
Copper has physical
properties:
• Reddish-orange
• Very shiny
• Excellent conductor of heat
and electricity
• Solid at 25C
• Melting point 1083C
• Boiling point 2567C

States of Matter
All substances known as matter exist in
one of three forms or states:
• Solids
Have definite volumes and shapes
• Liquids
Have definite volumes, but take the
shapes of containers
• Gases
Have no definite volumes or shapes

Chemical Properties
Chemical properties describe the ability of a
substance
• To interact with other substances
• To change into a new substance
Example:
Iron has the ability to form rust
when exposed to oxygen.

Chemistry 103
This course serves
as introduction into
the world of
chemistry, and
includes both
chemical and physical
processes.
Chemistry in Our Lives
Some of the chemicals you may encounter
when you cook in the kitchen are
•antioxidants in food
•metal alloys
•plastics
Historical Perspective
• Ancient Greeks
and the 4 basic
elements:
Air,
Fire,
Water &
Earth.
Historical Perspectives
Alchemists
• Attempted to turn base
metals into gold
• Attempted to find the
“Elixir of Life”
• Attempted to Produce the
“Philosopher’s Stone”
(base metals to Gold and
immortality)
Faust depicted in an etching by
Rembrandt van Rijn (circa 1650).
Scientific Method
The scientific method is
the process used by
scientists to explain
observations in nature,
how scientists think.
The scientific method
developed out of the
methods used by
Alchemists.
Copyright © 2005 by Pearson Education, Inc.
Publishing as Benjamin Cummings
The Scientific Method Involves
• observations, facts obtained by observing and
measuring events in nature.
• an hypothesis, statement that explains the
observations.
• experiments, procedures that test the
hypothesis.
• a theory, model that describes how
observations occur using experimental results.
Everyday Scientific Thinking
Observation: Yesterday you went to visit your
friend. Soon after you arrived, your eyes began to
itch and you started to sneeze. You observed that
your friend has a new cat.
Everyday Scientific Thinking
Hypothesis 1: Perhaps you are allergic to cats.
Experiment 1: To test your hypothesis, you leave
your friend’s home.
•If the itching and sneezing stop, perhaps your
hypothesis is correct.
•If the itching and sneezing do not stop, perhaps
you have a cold.
Everyday Scientific Thinking
Observation: Upon leaving your friend’s home, the
itching and sneezing stop.
•The observation supports your original hypothesis.
To confirm, you visit another friend with a cat.
Experiment 2: Visiting a second friend with a cat
causes your eyes to itch and you begin to sneeze
again, further supporting your hypothesis.
Theory: The experimental results indicate that
indeed you are allergic to cats.
Periodic Table
Primary resource for a chemist as well as other
scientists.
Lists all the known elements in a “periodic way”
Element - a substance that can not be broken
down into simpler substances by chemical
means.
