Answer: The freezing point depression is 
Explanation:
Depression in freezing point is given by:
= Depression in freezing point
= freezing point constant = 
m= molality = 
Thus freezing point depression is
Yes you are correct it is
The bond is highly polar is the scientific claim about the bond in the molecular compound HF is most likely to be true.
The term polar means that there is separation of charges, the bonds will be the more polar the greater the difference in electronegativity between the bonded atoms.
- In hydrogen fluoride, for example, F is more electronegative than H because its nucleus, with 9 positive charges, attracts e-shares with H more strongly than the nucleus of H, with only one positive charge.
- Therefore, the e- shared by covalence will be closer to F than to H and the molecule forms a permanent dipole.
Therefore, we can conclude that the bond is highly polar is the scientific claim about the bond in the molecular compound HF is most likely to be true.

Given , Speed of light = 3 × 10⁸ m/s
Distance = 40 × 1.61× 1000 m
= 264400 m
We know that, speed = distance/time
so, time = distance/speed
t = 264400 / 3 × 10⁸
t = 0.00881333 sec Approx
The answer is 0.00881333 sec Approx
Chadwick did!
Hope this helps!
