Which of the following pairs are not miscible? Group of answer choices hexane, C6H14 and water benzene, C6H6 and hexane, C6H14 ethyl alcohol, CH3CH2OH and water methyl alcohol, CH3OH and water pentane, C5H12 and hexane, C6H14

Hexane, C6H14, and water.

Explanation:

The highly polar group molecules are completely soluble in water because of the polar nature of water. Only the polar compounds or molecules can dissolve in water because poles of polar molecules attract by the poles which are present on water molecules.

Hexane is known as a pure hydrocarbon and non-polar in nature so, it does not have the ability to fulfill requirements of hydrogen bonds that why Hexane is immiscible in water.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
