Chemistry
Chemistry (from Egyptian kēme (chem), meaning "earth"[1]) is the science concerned
with the composition, behavior, structure, and properties of matter, as well as the
changes it undergoes during chemical reactions.[2] It is a physical science for studies of
various atoms, molecules, crystals and other aggregates of matter whether in isolation
or combination, which incorporates the concepts of energy and entropy in relation to
the spontaneity of chemical processes.
Chemistry is often called “the central science" because it connects the other natural sciences
such as astronomy, physics, material science, biology, and geology.[5][6]
Disciplines within chemistry include inorganic chemistry, organic chemistry, biochemistry,
physical chemistry, analytical chemistry. Many more specialized disciplines have emerged in
recent years, e.g. neurochemistry the chemical study of the nervous system (see
subdisciplines).
Chemistry is an integral part of the science curriculum both at the high school as well as the
early college level. At these levels, it is often called "general chemistry" which is an
introduction to a wide variety of fundamental concepts that enable the student to acquire
tools and skills useful at the advanced levels, whereby chemistry is invariably studied in any of
its various sub-disciplines. Scientists, engaged in chemical research are known as chemists.[9]
PRS Question #1:
Thinking of what you want to get out of your
college education and this course, which of
the following is the most important to you?
1.Acquiring information (facts, principles,
concepts)
2. Getting a good grade
3. Learning how to use information and
knowledge in new situations
4. Developing lifelong learning skills.

Chem 31A Philosophy
• Two week learning cycle through lectures,
lab sections, outreach sections, office hours,
homework...
• Introduce new phenomena, conceptual models
• Build problem solving skills
• Units and unit conversion are important
• Understand/explain chemical phenomena in daily life
(link chemistry with every day life)
• Assess mastery of the above in quiz/exams
Your course grade will be determined on an
absolute basis. You are NOT competing against
one another
There are a total of 1000 points available:

Objectives/Skills developed in Chem 31A:
• You will understand the structure of matter and the
types of energy associated with chemical
transformations
• You will develop:
– the ability to construct your own conceptual
understanding of physical systems through a progressive
sequence of observation, experimentation, reading,
discussion, argument and writing.
– critical thinking skills to analyze and solve scientific
problems.
– communication skills to discuss science and to explain
your understanding in writing.
– the ability to demonstrate your command of scientific data
and conceptual models in written exams.

What’s out big end goal?
Be able to apply chemical concepts to
understand, explain, and solve problems
in new situations:

MJT4&feature=related
How do we work together to become
better scientists?
• Read the assigned material and do practice
problems BEFORE lecture
• Lectures will be a time to discuss and engage with
the material
• You will have at least 40 PRS questions this quarter
- help both me and you gauge your understanding
of the material
• Sections will give you the chance to experiment and
observe chemical phenomena – from which you will
work to generate models or key concepts
Lab Clean-up
SAFETY FIRST!
• None of your skin (including your feet) should be
visible except your head and hands even when
bending over the lab bench
• Lab coats can be purchased at Chemstores with
credit card or bring clothes to change into (shoes,
long pants, sleeves)
• Safety goggles must be worn at all times in the
laboratory on experiment days.
• Know the location of the exit, fire blanket,
extinguisher, and first aid kit
• During an earthquake, take cover in the recesses
under the lab benches until the shaking stops,
and then evacuate to the Emergency meeting
point – Mudd Lawn.
Which of the following are
acceptable to wear in the lab?
1)
3)
4)
2)
• Only pure water can go down the sink.
• Discard all chemical waste in the proper
container: acid, base, or heavy metal.
• If any chemicals go down the sink, the county is
alerted, which can result in shutdown of all
research in the Mudd building.
• Rinse all disposable or broken glassware with
ethanol before discarding it in the broken glass
waste container.
• Rinse all regular glassware with ethanol before
placing it in the bins for the glassware washer.
Which of the following are
