Question

e. a pure substance made up of two or more elements that are chemically combined
f. a process in which a mixture is separated using differences in boiling point between the different components of the mixture
g. a mixture whose components cannot be distinguished and that appears as a single phase
h. a mixture whose components can be distinguished
compound
element
mixture
distillation

Explanation:

A compound is a pure substance made up of two or more elements that are chemically combined. Distillation is the process of separating a mixture using differences in boiling - point. A homogeneous mixture has components that cannot be distinguished and appears as a single phase, while a heterogeneous mixture has distinguishable components.

Answer:

E. compound
F. distillation
G. homogeneous mixture (not listed in options but for clarity)
H. heterogeneous mixture (not listed in options but for clarity)
