Course Description

• Chemistry 101 is a 5 unit course in general
  college chemistry. The course combines about 3
  hours of lecture with two 2 hour laboratory
  sessions and 2 hours of conference per week.
  Students should have knowledge of college algebra
  with a minimum grade of "C". Chemistry 101 is a
  college level course in general inorganic
  chemistry. The course is designed primarily for
  students who have had previous chemistry training
  either in high school or an elementary course at
  a community college. A minimum grade of "C" in
  this course is necessary in order to enroll in
  Chemistry 102.

Academic Integrity

• Board Rule 9803.28
• Students found cheating will receive a grade of
  F for the quiz/exam, and will be recommended to
  the Dean of Students for expulsion from the
  college.

Financial Aid

• If you need help paying for books and other
  college expenses, call the Financial Aid Office
  at [phone] extension 2010, or see them at
  Student Services Village room 117.

Student LearningOutcome

• By the end of this course you will be able to
  solve a stoichiometry problem in which the
  limiting reactant is not identified in the
  problem. Given a stoichiometry problem in which
  the limiting reactant is not identified in the
  problem, the student will be able to correctly
  interpret the problem, develop a correct
  solution, and generate a correct answer to the
  correct number of significant figures.

12
Science and Technology

• Science is the process of seeking an
  understanding of underlying principles of nature.
  Science involves two facets
• Technological (or factual) and philosophical (or
  theoretical).
• Technology is the direct application of knowledge
  to solve problems.
• Science grew out of natural philosophy or the
  philosophical speculation of nature

13
Science

• Scientific laws are descriptions of natural
  phenomenon. (Law of Gravity, Law of Conservation
  of Mass/Matter)
• Many scientific laws can be stated
  mathematically.
• i.e., Boyles Law (PV k)

14
Science

• A scientific theory is a set of tested hypotheses
  that explain natural phenomena. Scientific
  theories are the best current explanation for
  natural phenomena. Theories are always tentative
  and may change as observations of nature change.

15
Science

• Scientific models are tangible items or pictures
  used to represent invisible processes.

16
Limitations of Science

• Science is limited to studying that which is
  observable, and natural processes in which
  variables can be controlled.

17
Science and Technology Risks and Benefits

• Science and technology are interrelated. They
  involve both risks and benefits.
• Risk-benefit analysis involves an estimation
  called the desirability quotient (DQ).
• DQ Benefit
• Risks

What is Chemistry? Definition Chemistry is the
study of matter and its changes from one
substance to another. Chemistry is central to
all sciences and overlaps with physics, biology,
geology, and astronomy. Learning about chemistry
teaches you about the benefits and risks
associated with chemicals and will help you to be
an informed citizen and make intelligent choices
concerning the world around you. Chemistry
teaches you to solve problems and communicate
with others in an organized and logical manner.

Chemistry is called the central science as the

• Major Chemistry subdivisions
• Analytical (qualitative and quantitative)
  Chemistry
• Qualitative Analytical Chemistry What is a
  sample of matter composed of?
• Quantitative Analytical Chemistry How much
  stuff is in a sample of matter?
• Physical Chemistry
• The study of the physics involved with chemical
  changes.
• Organic Chemistry
• The study of properties and reactions of
  compounds that contain Carbon
• Inorganic Chemistry
• The study of properties and reactions of
  compounds that are not Carbon based
• Biochemistry
• The study of living systems (Biology Chemistry)

• Major Hints in being a successful Chemistry
  Student
• Study Everyday!! A 5 unit class requires at least
  10 hours/week of study time to earn a C
• Dont fall behind you will never catch up!!!
• Always ask for help when you need it dont
  wait.
• Working in groups is very helpful IF you have the
  right group!!!
• Read the chapter and/or online lecture notes
  before class to familiarize yourself with the
  material.
