CHM 109 Lecture Notes - Lecture 2: Kinetic Theory Of Gases, Lewis Structure, Systematic Chaos
Document Summary
2 matter & energy (c&p 5th ed. ) revised f 2014, 6th ed fall 2015 and 2016. Practice questions from the end of the chapter,4th ed, pp. 42+ and 6th ed pp 42+: 11,13,15,19,21,22,23,33,35,37,39,41,43, 53, 55, 71. Chemistry is the study of matter and energy in chemical and physical changes. Space-filling, ball-and-stick, lewis dot diagrams, formulas, line-angle drawings. Line-angle drawings represent carbon chains and rings ! this is 5 carbons in a chain. A . kinetic molecular theory says that different states of matter are possible for one substance because it consists of tiny particles in constant motion. Water can be separated by electricity into hydrogen and oxygen. These changes are detected by color change, heat production, heat absorption (feels cold), change in melting or boiling point temperature, formation of a precipitate (a solid), a change in density, etc. see ch 8. 1 , p 206.
