CHEM 105aLg Lecture Notes - Lecture 5: Sulfite, Binary Phase, Permanganate
Document Summary
Chapter 1 matter and measurement scientific study of matter (properties, interactions with other matter and with energy: except for the space in a vacuum. 1. 3 composition of matter pure substances: have constant compositions (diamonds: element: cannot be decomposed chemically into simpler substances but can be broken down using nuclear reaction, compound: can be broken down into elements. Mixtures: impure: homogeneous mixtures (solutions): visibly indistinguishable parts. Wine water, alcohol, sugar, grape extracts bronze: heterogeneous mixtures: can visually see the separated components sand & water, oil & vinegar, amber. M-mega (106), k-kilo (103), d-deci (10-1), c-centi (10-2), m-milli (10-3), -micro (10-6), n-nano (10-9), p-pico (10-12) Time: minutes, hours, days, etc. aren"t metric don"t increase by factors of ten, kelvin all kelvin temperatures are positive (an absolute unit of measure) 0 k cannot be attained only use k (unless calculating t) calculations that result in division or negativity (if use. 1 dm3 = 1 l = 1000 cm3 = 1000 ml.
