19
Q
  1. If the molar mass of gas A is greater than the molar mass of gas B,

A diffuses more rapidly than B

B diffuses more rapidly than A

they both diffuse at the same rate

neither diffuses because they interfere with each other

A

B diffuses more rapidly than A

20
Q

the molecules of A move faster than those of B

the molecules of A move more slowly than those of B

the molecules of both gases move at the same rate

the molecules move too quickly to determine which are moving faster

A

the molecules of A move more slowly than those of B

has a definite volume and shape

cannot be compressed

usually has a very high density

expands to fill the space it is in

A

expands to fill the space it is in

22
Q

all atoms contain neutrons

the charge of the protons balances the charge of the electrons

the charge of the protons cancels the charge of the neutrons

the total protons and neutrons equals the number of electrons

A

the charge of the protons balances the charge of the electrons
