i had the same question for my class lol, do u go to forest park?
(( PLEASE HELP QUICK ))Which expression can be used to calculate the ratio of the rate of effusion of gas A to the rate of effus
1 answer:
Answer:
The square root of the molar mass of B ÷ the square root of the molar mass of A
Explanation:
Graham’s Law applies to the effusion of gases:
The rate of effusion (r) of a gas is inversely proportional to the square root of its molar mass (M).
If you have two gases A and B, the ratio of their rates of effusion is

Answer : is the molecule that exhibit dipole-dipole forces as its strongest intermolecular force.
Explanation : The shape or geometry of given molecules of ,
,
,
and
are linear, linear, tetrahedral, trigonal planar and angular respectively.
The given molecules ,
,
,
are symmetrical molecules. These symmetric molecules cannot exists as dipole even they contain polar bonds. Thus, these molecules will not exhibit dipole-dipole forces.
molecule has polar bonds and unsymmetrical bonds as shown in attached image. This molecule cannot exhibit H-bonding. It exhibit only dipole-dipole forces.
Therefore, molecule exhibit dipole-dipole forces as strongest intermolecular force.
