When two atoms combine, the overlap of their atomic orbitals produces molecular orbitals.
Answer:

Explanation:
Hello.
In this case, given the heat of fusion of THF to be 8.5 kJ/mol and freezing at -108.5 °C, for the required mass of 5.9 g, we can compute the entropy as:

Whereas n accounts for the moles which are computed below:

Thus, the entropy turns out:

Best regards.
S2F6, is the correct answer I believe!
Yeah im here and i am alos getting bored to
what are you doing and how is your day ?
