A mixture of heptane (bp 98oC) and 1-propanol (bp 97oC) is not fully resolved using SE-30 as the stationary phase, but is easily separated using a column of DEGS. Explain with your own words.

Answers

A mixture of heptane and 1-propanol  easily dissolved using DEGS because diethylene glycol sussinate (C8H14O6) 1 propanol easily dilutes and retain surface.

What is mixture?

Generally, a mixture speaks to the joining of two different substance in other to achieve a different substance or something combining or becoming matched.

In conclusion, SE-30  is  neutral in nature, DEGs is a stationary phase containing a non-volatile liquid phase. It also includes polar group OH types,

Hence, using Hydrogen bonding it can easily bind  1-propanol.

Vibranium

Answers

Choosing the material with the highest specific heat capacity is ideal and true.

What is Specific heat capacity?

This is defined as the quantity of heat needed to raise the temperature per unit mass.

Insulators have a higher specific heat capacity as it takes more time for them to absorb heat thereby making it ideal in building an  insulated home.
