The attraction between two different
molecules with different chemical identities is
known as _____.
● cohesion
● viscosity
● capillary action
# adhesion
RATIONALE
Adhesion is the attraction of two different
types of molecules to one another. Capillary
action occurs when the adhesive forces are
greater than the cohesive ones, like when a
paper towel soaks up water. Viscosity is a
measure of fluid's resistance to
flow. Generally, greater cohesive forces lead
to higher viscosity because it make it harder
for the molecules to move past one another.
Which of the following is nonpolar AND has a
linear molecular geometry?
● HCN
● NH₃
# BeH₂
NO₂
RATIONALE
Be is the central atom and is an exception to
the octet rule, requiring only 4 electrons.
Since there are no lone pairs of electrons, the
Be-H bonds spread out from one another,
resulting in a nonpolar linear geometry.
One way to state Boyle’s law is, “All other
things being equal, the pressure of a gas is
_____ its volume."
●
● NO₂⁻
● unaffected by
● proportional to
