Document Summary

Mixture: (cid:1: homogeneous composition of mixture is uniform throughout (dissolve sugar in water) (cid:1, heterogeneous composition not uniform (sand & iron, physical process doesn"t change identity of substance. Used to separate mixtures (solid liquid) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Quantitative measured & expressed with a number. Chemical change or chemical process must occur (rusting corrosion or oxidation of iron) Extensive: depends on amount of matter (ex. Intensive: doesn"t depend on amount of matter (ex. * atomic mass unit (amu) masses of atoms * F = (9 f/ 5 c) x c + 32 f. Combine base units to derive appropriate units: v = m3 , dm3 , ml, 1 ml = 1 cm3, 1 dm3 = 1 l. Note: use scientific notation: 1 sig fig: 1 x 102.
