Which of the fallowing scientific claims about the bond in the molecular compound HF is most likely to be true?
DENIUS [597]

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.

A chemist wishes to prepare a stock solution of 1.25 M KI. She will be diluting a 3.25 M KI solution in order to obtain 0.355 L
strojnjashka [21]
0.137 L of the stock solution

M1V1 = M2V2
M1 = 3.25 M
V1 = This is what we’re solving for.
M2 = 1.25 M
V2 = 0.355 L

Solve for V1 —> V1 = M2V2/M1

V1 = (1.25 M)(0.355 L) / (3.25 M) = 0.137 L
