Boyle's Law - answer V1P1=V2P2
Volume and pressure are inversely proportional
Charles Law - answer V1/T1=V2/T2
Volume and temperature are directly proportional
Combined Gas Law - answer P1V1/T1=P2V2/T2
T must be in kelvin
Ideal Gas Law - answer PV=nRT
p = pressure
v = volume
n = moles
R = 0.821 L*atm/mol*k
, T = temprerature
emperical formula - answer (E.F) most reduced formula, ratio of
elements
ex: M.F = C6H12O6
(divided by 6)
E.F = CH2O
Molecular Formula - answer How the molecule actually exist
MF = C6H12O6
EF Molar Mass formula - answer Mm =drt/P
Daltons Law - answer Sum of all the partial pressures of gases in a
mixture eqauls the total pressure
KE Speed of the individual gas particle - answer 1/2 mu^2
m in kg/mol
Tempreature and KE speed are ______ proportional - answer directly
proportional
as Temp goes up so does KE
root-mean-sqaure speed - answer
Density for Gases - answer PM/RT
P = pressure
M = molar mass
R = 0.0821
