Final Review Flashcards
(31 cards)
IMF: permanent dipole (polar)
dipole-dipole force
IMF: all atoms, larger and heavier are stronger
Dispersion Force
Very strong Dipole-dipole; H bonded with F, N, or O
Hydrogen Bonding
ions attracted by electrostatic forces, very strong
ionic compounds
Hard and brittle, high melting point, solid at room temp, don’t conduct as solids
ionic compounds
NaCl, NH4Br, MgCl2
ionic compounds
packed tightly together with sea of electrons; electrons are the “glue” that holds everything together
metallic solids
range of melting points, malleable, ductile, conduct
metallic solids
diamond, silicone dioxide (sand), graphite
covalent network
held together with covalent bonds, very strong
covalent network
high melting point, hard, brittle, not conductive
covalent network
dissociates in water “salt”
ionic electrolytes
molecule compounds that react with water to ionize
covalent electrolytes
miscible
2 liquids mix
immiscible
2 liquids don’t mix, form layers
partially miscible
2 liquids partially mix and form layers
osmotic pressure of solution is less than osmotic pressure of blood
blood cells swell and rupture; hypotonic
osmotic pressure of solution is greater than osmotic pressure of blood
blood cells shrivel, crenation; hypertonic
is endothermic pos or neg delta H?
positive
what makes a reaction more disordered?
Mixtures, heavier atoms, more atoms
delta S is greater than zero is it spontaneous or non-spontaneous?
Spontaneous
delta G is less than zero is it spontaneous or non-spontaneous?
non-spontaneous
if volume is increased which way does equilibrium shifted?
whichever side with the most moles of gas
turns litmus red, reacts with metal to produce H2 gas
acids
