  3. SCOPE OF COURSE • Chemistry 120 is designed specifically to prepare the student for the one-year general chemistry course. • Plan to spend two hours per lecture hour and one hour per lab hour per week for studying, minimum

  4. Prerequisite • Good working knowledge of intermediate algebra.

  5. Text • Text: Cracolice/Peters, An Active Learning Approach, Grossmont Custom edition • Lab Book: Chem 120 Lab manual • Homework: OWL assignments (online homework), http://www.cengage.com/owl/

  6. Additional Materials • Calculator:Nonprogrammable calculatorcapable of scientific notation (may not be shared during exams). • Notebook: spiral or loose leaf for homework • Safety Glasses: Z-87 Safety goggles (purchased in bookstore), • Ink Pen: Fine Tip Black Sharpie pen and a blue or black ink pen. • Combination Lock: preferred V69 series (purchase from hardware store or bookstore)

  7. Grading • Exams 40% • Laboratory Assignments 25% • Quizzes 15% • Homework 10% • Final Exam 10% • Total 100%

  8. Grading Scale • A 100% - 88% • B 87% -78% • C 77% - 66% • D 65% - 55% • All grades may be subject to a (+/-) 1-2 % instructor evaluation of the student. • Must pass both lab and lecture to pass course!

  9. Make-up Policy • Quizzes/ Labs - No make up allowed. • Exams - Must be made up within 1 week of original test date. (With a reasonable, verifiable excuse).

  10. Supervised Tutoring Referral • Students are referred to enroll in the following supervised tutoring courses if the service indicated will assist them in achieving or reinforcing the learning objectives of this course: IDS 198, Supervised Tutoring to receive tutoring in general computer applications in the Tech Mall; English 198W, Supervised Tutoring for assistance in the English Writing Center (Room 70-119); and/or IDS 198T, Supervised Tutoring to receive one-on-one tutoring in academic subjects in the Tutoring Center (Room 70-229, 644-7387).

  11. Attendance • Regular attendance is mandatory - you may be dropped if you miss more than 6 hours of class (1 week). • You will not be dropped if you have not checked out of the laboratory! This means you may receive an F!!!!

  12. Academic Integrity Policy • All work must be your own! • Calculators will not contain cheat sheets! • See college catalog for more information, as well as the Grossmont Chemistry Departments Academic integrity Policy.

  13. Disabled Students • Students with disabilities who may need accommodations in this class are encouraged to notify the instructor and contact Disabled Student Programs & Services (DSPS) early in the semester so that reasonable accommodations may be implemented as soon as possible. Students may contact DSP&S in person in Room 110 or by telephone at (619) 644-7112 or (619) 644-7119 (TTY for deaf).

  14. Additional Information: • The maximum number of times a student may enroll in the same credit course is three times. • A student, through a combination of substandard grades (D or F) and withdrawals on their student record, may only take a class three times. • If a student, through a combination of substandard grades (D or F) and withdrawals, wishes to take a class for the fourth time, they must submit a petition to the Admissions and Records Office. Petitions will only be approved based on extenuating circumstances. • Military Withdrawals do not count in terms of repetition restrictions, nor do withdrawals that occur due to fire or flood

  15. Studying Chemistry • Be curious • Learn vocabulary (and nomenclature) • Keep current in the class. Don’t wait for a test • Form a study group • Do problems again and again!!

  16. Chemistry: An Introduction Chapter 1

  17. Chemicals • What are they?? • There is nothing you can touch or hold that is not made of chemicals.

  18. What is Chemistry? • Chemistry is the science of the properties, composition, and behavior of materials. • Chemistry is the science concerned with describing and explaining the different forms of matter and the chemical reactions or matter.

  19. Branches of Chemistry • Applied Chemistry - the search for and isolation of useful materials. • Theoretical Chemistry - Provides a chemical view of nature and explanations of natural processes.

  20. Chemistry is the Central Science

  21. Scientific Thinking • Make observation • Gather facts (more observations) • Propose hypothesis (tentative explanation) • Test hypothesis (perform experiment) • Gather more facts and generate new hypothesis • Re-test new hypothesis - Show that results are reproducible • Propose theory

  22. From Scientific Model • Hypothesis- a tentative explanation for an observation. (An unproven theory) • Experiments – tests that look for observable predictions of a hypothesis or theory • Laws – brief statements that summarizes past observations and predict future ones • Theories or Models - unifying explanation for a set of observations, facts, and laws

  23. Element Names and Symbols • Element Ele • name symbol • 1 or 2 letters (occasionally 3) • 1st letter is capitalized, 2nd letter is lower case.

  24. Nomenclature • Learn the names and symbols of the elements. • You must know 1st 36 elements + Rb,Sr, Cs, Ba, Ra, Zr, Ag, Cd, Sn, Sb, Te, I, Xe, Pt, Au, Hg, Pb, Bi, Rn, U
