5. 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.

6. Attendance
Attendance taken daily (sign-in) & carbon copies are collected at the end of each lab period for lab attendance.
Adding the class
Lottery in week 2 (must attend every class)
Dropping the Class
Drop by ______________________to drop without “W”
If you think you will not be able to complete the class, and earn a grade of “C” or higher, consider dropping the class before _________________.

8. 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.

9. Financial Aid
If you need help paying for books and other college expenses, call the Financial Aid Office at (323) extension 2010, or see them at Student Services Village room 117.

10. Student Learning Outcome
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.
&
The student will perform proper laboratory skills and techniques exhibited in first semester chemistry titration laboratory experiment, demonstrate correct analysis of data, and calculation skills.

11. 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

12. 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., Boyle’s Law (PV = k)

13. 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.

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

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

16. 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

17. 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.

20. 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)

21. 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”
Don’t fall behind – you will never catch up!!!
Always ask for help when you need it – don’t 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.
