test 1 – Chemistry Flashcard

sublimation/fusion/vaporization/condensation/deposition
sub: solid to gas (dry ice)
vapor: liquid to gas (more energy)
fusion: melting
depo: gas to solid

solid to gas is endothermic
gas to solid is exothermic

kinetic motion equation
KE=mv2
constant, randomn
no IMF in gas
london “dispersion”
all molecules; WEAK; big masses
depends on polarizability> more spread out ^
dipole dipole
week
polar
ion dipole
moderate
ion and a polar molecule
Hydrogen
NOT A BOND JUST IMF
bonds with: O, N, F
moderate
IMF and surface tension, viscosity, capillary action, vapor pressure and boiling poitn
IMF increases

surface tension, viscosity, capillary action, boiling point INCREASE

vapor pressure DECREASES

Temperature increase effects what
DECREASE in surface tension, viscosity, vapor pressure
phase diagram
triple: all three
critical: liquid/gas
water is less dense bc hydrogen makes 4 bonds
heating curves equations
solid to fusion to liquid to vapor to gas

e=m* change in H
e=mcat

solids types
crystalline “repeat” and amorphous “not repeat”
crystalline solid types
molecular: low melting point “ice”
ionic: high melting point “salt”
nonbonding: dispersion forces, low mp
metallic: various points, gold
network covalent: high MP, “quartz”
solution types
homogenous: transparent
colloids: cloudy/ not seperate
suspensions: solute is visible; will seperate with standing
electrolytes
strong: dissociation IONS
weak: partial diss; molec + ions
non: no diss
strong acids/bases
h2so4, hno3, hclo4, hcl, hbr, hi,
hydroxides of 1a, lower 2a
weak acids/bases
hf, h3po4
nh3
solubility chart
salts of 1A
NAPS
SLM SOLUBLE
BIC
CHOPS
Sulfats ex: ca, strontium and barium; SOLUBLE
saturated/unsaturated/supersaturated
sat: equal with undissolved solute
unsat: less than equal of solute
super: more than equil of solute
ppm
10 to the 6
ppb
10 to the 9
minisible vs imminisible
minis: homogenous
imm: oil and water
solibility factor
temp: ^ solub. ^, gas solub decreases
concentra: unsat>sat>supersat
agitation: dispersing particles
surface area: smaller
pressure: ^ pressure ^
colligative properties
decrease vapor pressure, freezing point
incease boiling point
osmotic pressure

MORE MOLES MORE COLLIGATIVE PROPERTIES

Osmotic pressure
isotonic: equal
hypotonic: high concentration outside
hypertonic: high concentration inside
