Answer:
B
Explanation:
To form hydrogen bondings between the molecules, the compound needs a highly electronegative atom (usually N, O, or F) bonded with a hydrogen atom;
and that the highly electronegative atom has lone pair outermost shell electrons.
In the 5 options, only B (CH3OH) has an N, O, or F atom that has lone pair outermost shell electrons (2 lone pairs on each O atom), so it can form hydrogen bonds within its molecules.
Hydrogen bonds are stronger than the van der Waals' forces between its molecules (that exist regardless of whether there are hydrogen bonds).
Answer:
the heat capacity of steam is 2.01 J/(g⋅∘C) and of ice is 2.09 J/(g⋅∘C). 1. See answer.
Answer:
You need to heat the mixture to 78.37°C
Explanation:
In distillation, you can separate 2 or more compounds based on their difference in boiling points.
In a mixture of ethanol and water, in theory, you need to heat the mixture to 78.37°C. In this temperature, the ethanol must be evaporated and then condensed in the receiving flask.
