Chemistry
Pure Substances
Def: consists only one substance
example: tap water is not pure substance
an element of compound
Heating+Cooling of stearic acid
melting/freezing point (MP
H2O: 0C
BP-Boiling Point
H2O: 100C
Separation Methods
Evaporation
soluble solid from liquid
Magnetism
magnetic from non magnetic
Distillation(蒸馏
liquids with different BP
simple
Must have LARGE DIFFERENCE IN BP
fractional-same but w/ glass beads
Use: sep crude oil+purify water
Chromatography
liquid of different colors
pencil line bc it can't be dissolved into water
ink above the line- dissolves on the paper and spreads
use: criminology
Filtration
an insoluble solid from a solid liquid mixture
Decanting
separate mixtures w/ different densities
Solubility-the ability to dissolve
Metal Compounds+Reactions
metal+ Acid
metal salts can be made
metal oxide+Acid-->Metal salt+water
Sulphuric Acid=H2SO4
metal +oxygen-->metal oxide
magnesium+oxygen-->magnesium oxide
PPT
2 soluble substance-->soluble substance+insoluble substance
WORD EQUATION: metal+metal-->metal compound+metal solution
metal compound=PPT
example: Potassium Iodide+Lead Nitrate--->Lead Iodide+Potassium Nitrate Lead Iodide=PPT
Iron-Green Copper-Blue Calcium-White
Hydroxide-PPT
Potassium, Lithium, Sodium-no PPT

Basics
Must know elements(damn)
Hydrogen-H
Na-Sodium
Lithium-Li
Mn-Maganese
K-Potassium
Si-Silicon
Hg-Mercury
P-Phosphorus
N-Nitrogen
Ca-Calcium
Fe-Iron
Cu-Copper
Ni-Nickel
Ag-Silver
Zn-Zinc
Au-Gold
C- carbon
Pb-lead
Al- Aluminium
Sn-Tin
O-Oxygen
S-Sulfur
F-Fluorine
Cl- Chlorine
Br-Bromine
I-Iodine
balance reactant and product: Pb+O2-->PbO=2Pb+O2--->2(PbO)
Dilute=less concentrated
