Document Summary
Chem121 - lecture 1 - intro to chemistry. Midterm (monday, june 29th, 6:00pm - 8:00pm) Final (wednesday, august 12th, 8:30am - 11:30am) Mostly based on info from chem 11 (high school) The names, symbols and position in the periodic table of the first 36 elements in the periodic table for the first midterm. The names of cations and anions in tables 2. 3 - 2. 5 and those in the table of polyatomic ions posted on the canvas page. The names of acids in tables 2. 7 - 2. 8. Chemistry is study of matter, its properties, and composition. Physical properties are properties that can be observed without changing the chemical identity (ex. colour, mass, mpt, density) Chemical properties are properties that matter shows as it undergoes or resists change in chemical composition (ex. reactivity (or lack thereof) with oxygen => rust) Si units: derived mostly from metric system. Meter (m), kilogram (kg), second (s), kelvin (k), mole (mole), ampere (a)
