  3. Chemistry 120 is designed specifically to prepare the student for the one-year general chemistry course.

  4. Prerequisite • Good working knowledge of intermediate algebra.

  5. Text • Zumdahl, “Basic Chemistry,” • Homework packet • Lab manual

  6. Additional Requirements • Calculator: Capable of scientific notation (may not be shared during exams). • Notebook: spiral or looseleaf for homework • Safety Glasses: Z-87 Safety goggles (purchased in bookstore), • Ink Pen (for laboratory write-up) • Combination Lock: (purchase from hardware store or bookstore)

  7. Grading • Exams 35% • Laboratory Assignments 25% • Quizzes 15% • Assignments, WebCT 10% • Final Exam 15% • Total 100%

  8. Grading Scale • A 89% • B 79% • C 65% • D 56% • Must pass both lab and lecture to pass course!

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

  10. Late Work • Labs - lose 20% per week late. No labs accepted more than 2 weeks late. • Assignments WebCT and Homework sheets

  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. 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!!

  15. Chemistry: An Introduction Chapter 1

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

  17. 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.

  18. 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.

  19. Chemistry is the Central Science

  20. 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

  21. 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

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

  23. 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
