genchem midterm examz Flashcards
the particle of this matter has complete freedom of motion
gas
it is the fundamental difference of particles between the state of matter
distance
their particles are closer together so it is referred as condensed phases
solid and liquid
the particle of this matter is free to move relative to each other
liquid
what is the density of liquid
high
this matter assumes the shape of the container it occupies
liquid
when the kinetic energy increases, the intermolecular attraction
decreases
what is the diffusibility of solid
extremely slow
force of attractions between an instantaneous dipole and an induced dipole
london dispersion forces
the tendency of an electron cloud to distort
polarizability
in this force, molecules that have permanent dipoles are attracted to each other
dipole-dipole interactions
these forces are present in all molecules, whether they are polar or nonpolar
london dispersion forces
these forces are only important when the molecules are close to each other
dipole-dipole interaction
the bonding of electrons shared unequally between atoms
polar covalent bond
the strength of these forces are what makes it possible for ionic substances to dissolve in polar solvents
ion-dipole interactions
the force when hydrogen is bonded to one of those very electronegative elements
hydrogen bonding
TRUE OR FALSE: The normal boiling point is the temperature at which its vapor pressure is 750 torr
False
TRUE OR FALSE: As pressure increases, the solubility of gas in liquid increases
True
True or False: Aqueous solutions are solutions in which water is the solvent
True
True or False: Vapor substances are substances that evaporate easily
False
true or false: When the solute is non polar and the solvent is polar, then it is soluble/miscible
False
true or false: stirring increases solubility of solids in liquids
true
when the solvent is liquid and the solute is solid, the final state will be solid
false
it is an endothermic reaction when the solubility decreases with an increase in temperature
false
it is insoluble if the solute is greater than or equal to 10g dissolves in 100g of solvent
false
