    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!

    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

    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
