You just calculated that the heat of fusion for chloromethane is 6400 j/mol. the heat of fusion for hydrogen is 120 j/mol. which of the following account for this difference? check all that apply. view available hint(s) check all that apply. hydrogen molecules can pack more closely than chloromethane molecules. chloromethane can absorb more energy at the same temperature. chloromethane experiences dipole-dipole interactions. hydrogen has stronger intermolecular forces than chloromethane. chloromethane has a higher molar mass than hydrogen.

Chloromethane experiences dipole-dipole interactions.

Chloromethane has a higher molar mass than hydrogen.

Explanation:

The molar mass is directly proportional to the heat of fusion, since the heavier the molecules the more energy they need to separate. Intermolecular forces are also directly proportional to the heat of fusion, because the greater the interaction they experience, the more energy they require to separate. The dipole-dipole interactions experienced by chloromethane are stronger than the interactions that take place in hydrogen.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
