Answer:
Why do you need good toothpaste?
Explanation:
Oxygen atoms and sulfur atoms form compounds with similar molecular structures because if you look at these two, they both have six electrons in their valence shells. Therefore, they will generally react in much the same manner. I hope this helps you on your assignment.
Explanation:
More is the intermolecular forces present between the molecules of a substance more will be the boiling point of the substance.
Since, water is able to form hydrogen bonding and it also have dipole-dipole interaction as these are stronger than the forces present in ammonia. Hence, boiling point of water is greater than the boiling point of .
In , there are only dispersion forces present in it and these forces are weakest intermolecular forces.
As a result, the enthalpies of vaporization of the following substances increase in the order .
