balancing
cheminstry
changes in matter
chemical changes
changes in the molucules of a substance
photosynhisis
O2
H2O
O2
rotting food
physical changes
state(solid,liquid and gas)
liquid
evaporate
freeze
gas
precipitation
condensation
solid
melt
gas
deposition
solid
sublimation
shape
charecteristic properties
density
how much g per cm3
meting point
the point that something melts at
boiling point
the point something starts to boil at
malleable
how easy to morph
ductile
how easy it is to stretch
magnetism
how much a material attracts other magnets
conductivity
how easy electricity travels through a matrial
solubility
how it melts in solvents
luster
how shiny something is
flame test
the color something burns at
litmus
accididty test paper
specific heat capacity
how much energy is needed to change the temp
reactivity
a particals let off from a material
reactivity with oxygen
does it rust or tarnish?
mixtures
different types of solutions
saturated
the solvent cant dissolve more solute
unsaturated
the solvent can dissolve more solute
super saturated
too much solute is mixed with the solvent. extra solute settles to the bottom
all solution types
pure substance
mixture
homogeneous
heterogeneous
suspension
colloid
different types of solubility
solubility
dissolving a certain amount of solute in a solvent
concentration
diluted
lots of solvent and little solute
concentrated
lots of solute little solvent
percent
solute amount / total volume
parts per million
PPM=x Grams/ 1000 liters
example
3.78mg / 50 ml =
consentration from dilution
C1V1=C2V2
C1= starting concentration
V1= starting volume
C2= concentration after
PH scale
a scale between acidic and basic
it goes from 0 to 14
you can taste these
7 is neutral
each step on the scale is 10x greater/less than the next step
you can test this via litmus test
hydro chloric acid
water + sodium
sodium hydroxide
naming ionic compounds
example
potassium + bromine
potasium bromide
if there are only 2 elements in the compound the word ends in ide
compunds containing transition metals
hint:keep an eye on the total negative charge and remember the positive must cancel it
examples
FE(iron)+O(oxide)
FE(III)
Fe2 O3
O(-II)
Ag2 O
silver oxide
Pb c
lead carbide
Cr P
chronium phosphide
Ca I2
calcium iodide
N Br

FACT:ther are three transition metals that dont use roman numerals
Ag= +1
Al= +3
Zn= +2
