ACS Chem Flashcards
increased vapor pressure….
decreased surface tension
decreased vapor pressure….
increased surface tension
Graham’s Law of Effusion
lightest weight effuses the fastest
melting point =
freezing point
cubic solid and poor electric conductor in solid state
crystaline solid like sodium chloride
melting point decreases… this is attributed to ???
freezing point depression
Ideal gases break from conditions at what conditions?
low temp - IMF significant;
high pressure - gas does not become compressible
solutions
homogeneous mixtures
Cooling curve and a long horizontal line…. depends on
the heat of melting of a pure substance
soft, poor conductor of heat and electricity
network covalent
CO2 as dry ice is what kind of solid?
molecular solid
Vapor Pressure and Raoult’s Law
XaPA + XbPB
VAPOR PRESSURE depends on
temperature
boiling point occurs when
temperature and pressure at equilibrium
PV=nrt; but what about finidng molar mass
PV = nRT n= Mass/ MM
solubility decreases as you go in what direction of the periodic table
decreases as you go down the periodic table
pure substances
the substances that have the same of the same……. they could be grouped together and seen throughout
