forces. - Correct Answer low, indefinite, indefinite.
weak
Liquids have a ___ density, ___ shape, and ___ volume. These qualities are due to ___ intermolecular

moderate
Solids have a ___ density, ___ shape, and ___ volume. These qualities are due to ___ intermolecular
forces. - Correct Answer hihgh, definite, definite
strong
Solids can be ___ or ___. - Correct Answer Crystalline or amorphous
Amorphous solids are composed of atoms or molecules that exhibit ___. - Correct Answer no long range
order
,Crystalline solids are composed of atoms or molecules that exhibit ___. - Correct Answer definite order
in a three dimensional array
What two things can be changed in order to transform one state of matter to another? - Correct Answer
Temperature and pressure
In general, increases in pressure favor the ___ state. - Correct Answer Denser
Intermolecular forces originate from - Correct Answer the interactions between charges, partial
charges, and temporary charges on molecules (or atoms and ions)
_____ Law stat
decreases (becomes more negative) with increasing magnitude of charge and decreasing distance
between the two particles - Correct Answer Coulomb's
Equation of Coulomb's Law is -
Why are intermolecular forces much weaker than bonding forces? - Correct Answer Bonding forces are
result of largue charges on protons and electrons interacting at very close distances, and intermolecular
forces are the result of smaller charges interacting at greater distances
What are the four main types on intermolecular forces? - Correct Answer Dispersion, dipole-dipole, H+
bonding, and ion-dipole
Dispersion forces are the result of ___. - Correct Answer fluctuations in the electron distribution within
molecules or atoms which induces a temporary (or instantaneous) dipole
Dispersion forces are exhibited by ___ and increase with ___. - Correct Answer atoms/molecules
increasing mass
The magnitude of dispersion forces depends on how easily the electrons can ___. - Correct Answer
move or polarize in response to an instantaneous dipole
, A larger atom exhibits greater dispersion forces because - Correct Answer the electrons are held less
tightly by the nucleus and therefore polarize more easily
Dispersion forces are directly related to not only mass but ___. This is due to the molecules ability to
___. - Correct Answer shape
stack efficiently
Dipole-dipole forces exist in all ___. - Correct Answer Polar molecules
Dipole-dipole forces are due to the effects of a molecule's ___, which is due to ___. - Correct Answer
permanent dipole
a molecule's partially positive and partial negative ends
Polarity of molecules determines their miscibility of liquids. What is miscibility? - Correct Answer the
ability to mix wihtout separating into two states
In general polar liquids are miscible with ____, but are not miscible with ____. - Correct Answer polar
nonpolar
Hydrogen bonding exists in all ___. - Correct Answer molecules containing a hydrogen atom directly
bonded to a nitrogen, oxygen, or flourine
Hydrogen bonding is due to - Correct Answer the large electronegativity differences between the H+
and -F, -O, -N
A typical hydrogen "bond", despite it being the strongest intermolecular force, is only about ____ as
strong as a covalent chemical bond. - Correct Answer 2-5%
Ion-dipole forces occur when - Correct Answer an ionic compound is mixed with a polar compound
and liquid
