Chem. 110 Spring 2008 T. Miles Lesson I : Intro., Measurement (Chs. 1&2) Objectives: Introduce scope of chemistry and the scientific method. Discuss uncertainty in measurement. Discuss significant figures (S.F.’s). S.F.’s and calculations. Chapter 1: Introduction to Chemistry I.) Chemistry A.) Scope : study of structure and interactions of matter. B.) Main Branches Physical : quantitative study of chemical structure and reactivity using laws of physics. (e.g. study of rxn. rates) Organic : study of properties and rxn’s. of C-containing compounds. (e.g. refining of crude oil to gasoline) Inorganic : study of properties and rxn’s. of compounds not containing C. (e.g. developing catalysts for catalytic converters) Biochemistry : study of chemical processes in living organisms. (e.g. cancer research) Analytical : development and implementation of instrumentation and techniques for use in chemical study. (e.g. new methods for soil analysis) C.) Applications (Look around. It’s everywhere!) Environment Medical Industry Computers/microtechnology Food/beverage II.) Scientific Method : set of logical steps taken by scientist employed in an effort to better understand nature. Step 1: define problem (ask question). (e.g. Why does it get overcast during the month of June in Glendora, CA ?) Step 2: gather data through experimentation.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
