Which of the following statements about fractional distillation are true. a. The distillation process involves several concurrent vaporization-condensation cycles.
b. For good separation by distillation the volume of liquid condensing back to the pot should be lower than the volume of liquid distilling off.
c. Continual change in boiling temperature is observed as the distillation progresses.
d. The lower the HETP (height equivalent to a theoretical plate) of the fractionating(packed) column the more efficient it is at separation of components.
e. Can ideally separate mixtures with comparable volatilities small BP differences.

Answer    "a salt" would be the best answerexplanationsalts can be defined as ionic compounds that are neither acids nor bases. nacl is an example of a salt, and its ionic.an enzyme is an organic compound which is covalently bonded, not ionically bonded.acids are generally held together by covalent bondsan element does not need any bonds to exist
