Answer:
17.6510 L
Explanation:
First we should get the number of moles of helium here by Boyle's law
PV=nRT
P=750/760= 0.9868 atm
T=25+273=298 kelvin
R= 0.08206
V= 20L
so
n=PV/RT
n=0.9868×20/0.08206×298
n=0.80707 mol
Then use the same law
V=0.80707×0.08206×263/0.9869=
17.6510L
SO THE VOLUME WILL BE 17.6510 L
<span>Although two centuries old, Dalton's atomic theory remains valid in modern chemical thought. 1) All matter is made of atoms. Atoms are indivisible and indestructible. 3) Compounds are formed by a combination of two or more different kinds of atoms.</span>

Explanation:
Things can only go downhill from here
Answer: pentanol>pentanal>pentane
Explanation:
Pentanol will have the highest viscosity, boiling point and surface tension because it has the highest degree of intermolecular interaction. The molecules of pentanol are held together by strong intermolecular hydrogen bonds which raises its boiling point. This degree of intermolecular interaction is absent in pentanal and pentane. They have much lower boiling points with pentane having the lowest boiling point due to the presence of weak London forces.
