what must hydrogen bonding molecules contain? -
....ANSWER...first must contain H covalently bonded to O,
N, or F; the second must have O, N, or F w/ lone pair
the lone pair on the O, N, or F in a hydrogen bond has a
large delta (positive/negative) charge -
....ANSWER...negative
H-bonds are also strong _______ interactions -
....ANSWER...dipole-dipole
compounds that have H-bonds also have what IMFs? -
....ANSWER...dipole-dipole interactions and LDFs
properties of water are: - ....ANSWER...anomalous
,ice takes up what form? - ....ANSWER...hexagonal crystal
why does ice take up a hexagonal crystal form? -
....ANSWER...b/c of the 4 hydrogen bonds around each
water molecule
NaCl forms in what way? - ....ANSWER...colorless
crystals; cubic in shape; hard and brittle
melting point of NaCl - ....ANSWER...802°
when does NaCl conduct electricity? - ....ANSWER...when
melted
simple ionic compounds contain: - ....ANSWER...a metal
and a nonmetal
ionic compounds also contain one element w/ _____ and
one element with ______ - ....ANSWER...low
electronegativity (metal); high electronegativity
(nonmetal)
,metals form (cations/anions) - ....ANSWER...cations
non-metals form (cations/anions) - ....ANSWER...anions
each ion typically achieves _______ configuration -
....ANSWER...noble gas
what happens to a system when an ionic compound forms?
(stabilized/destabilized) - ....ANSWER...it is stabilized
ionic compounds are positive/neutral/negative??? -
....ANSWER...neutral
Each Cl- in NaCl is surrounded by ____ Na+ ions? -
....ANSWER...6
Each Na+ in NaCl is surrounded by ____ Cl- ions? -
....ANSWER...6
, cations are (positively/negatively) charged -
....ANSWER...positively
cations are (larger/smaller) than corresponding atom? -
....ANSWER...smaller
when metals lose electrons, what is formed? -
....ANSWER...simple cations
charge of cations usually corresponds to: -
....ANSWER...loss of electrons back to "core" but not b/c
this is more stable
loss of electrons requires: - ....ANSWER...energy
why do cations form? - ....ANSWER...highly charged ions
form stronger bonds--which are more stable
anions are (positively/negatively) charged -
....ANSWER...negatively
