Document Summary
Acid vs. base: if base, add h for acid, if acid, take out h for base. A = atomic mass (p + n) Alkanes: methane = ch4, ethane = c2h6, propane = c3h8, butane = c4h10. Combustion: propanol c3h7oh, octanol = c8h17oh, complete, incomplete. O2 co & h20: acetic vinegar, citric lemon juice, ascorbic vitamin c. Phosphor emits light due to excited electrons, not heat. Superfund sites: if acid has to react with water to be strong, polluted locations requiring a longterm response to clean up hazardous material contaminations, determined by epa. Sdwa safe water drinking act 1974. Chromatography: physical separation, stationary more polar than mobile, rf = how much moved / total possible movement. Flocculating agents: traps material not wanted (fine particulate material) [h30] = 10^-5. 3: 5. 3 to 4. 3 = 1000% increase in [h30] Ph levels: dead @4, most life gone @5, many fish gone @5. 6, normal @7-9.
