the intermolecular forces will be less in gaseous state and hence is less stable
Answer: This is true.
Explanation:
It is true because if becomes frozen, then it is physically harder to melt...
Answer:

Explanation:
The total amount of atoms is found by multiplying Avogradro's Number and the number of moles:


Answer:
For H-Cl, the direction is towards the chlorine atom
For F-CH3, the direction is towards the flourine atom.
Explanation:
The dipole moment is a vector quantity. This implies that it has both magnitude and direction.
Thus, the direction of the dipole moment always points from the positive atom towards the negative atom.
This explains the fact that it points to chlorine in HCl and points to flourine in F-CH3
