emrpical
gas law
heat transfer
273 to go from kelvin to Celsius
plug into missing variable
1 atm is 760 torr
gasses go low pressure high temp
PV=NRT
add up ending subscripts to find formula
combustion yields oxygen as product
convert to mole, divide by small, multiple till whole
ionic compounds always come in empirical!!!!
100g=100%
avagadros law is volume is proportional to moles
partial pressure you add up all the moles of the substances
q=mcat
goes from hot to cold
find missing variable to solve for specific heat
phase changes have certain equations
vapor is going to gas and fusion is going to liquid from solid
vapor solid liquid 3 phases
phase change multpily by grams to find amount then add to equation
1010.325 KPA
prsrrue and volume inversely related
Kienetics
solutions
Equilirbrium
convert from ml to l
to find mol use gram conversion
M=mo/vol
solute is dissolved nine solvent
concentration affects rate
only use liters
homogenous mixture means you can't see the different particle
hettrogeonous you can see the mistures
adding substance doesn't affect the equation
products/reactents t find eq
shift to opposite side of whats added except volume
q>k shift left,
rate law powers the number of mols
ICE table to find values
pressure and volume inversely related
must be in kelvin
q<k shift right
plug in any row of tables and it works
solids don't count but AQ does
r=k(a)^x(b)^y
any unit of measure is fine
difference in order you're trying to find
kinetics is equal in all gasses
change in temp goes on bottom
must be in kelvin
Salts/solutinos
acid and base are determined by molecules
determined by OH and H molecules
-log
used to neutralize most reactions
acid is below 6
base is aove 7
more acid is sour
base is bitter
