CHEM 125 Lecture Notes - Lecture 1: Significant Figures, Si Derived Unit, Scientific Notation
Document Summary
Bring to class a notebook, writing utensils, a calculator, your i>clicker, and the periodic table. Packet posted on canvas > files > additional documents. Note that i>clicker questions recorded during lectures 1 and 2 (l1 & l2) will be posted in the canvas gradebook, but the scores will be dropped at the end of the term. We post these scores so that you can ensure that your clicker is properly registered on canvas. Finally, bring this outline to class so that you do not have to frantically copy down the text of problems presented on the lecture slides. L1 reading assignment: zumdahl & zumdahl r. 1 r. 4. All quantitative observations consist of a number and units. Know common prefixes and their exponential notation (highlighted in blue in table r-2). R. 3 significant figures and calculations (we will review quickly in class) Rules for counting significant figures: nonzero integers, zeros, leading zeros, captive zeros, trailing zeros, exact numbers.
