A chemical reaction was used to separate a sample into its components. What conclusion about the sample can be formed based on the technique used?

Question

a It was a pure substance.
b It was a compound.
c It was a heterogeneous mixture.
d It was a homogeneous mixture

Answer 1

The most appropriate conclusion about the sample based on the technique used is:

b) It was a compound.

Chemical reactions are typically used to separate mixtures into their individual components. Since a chemical reaction was used in this case, it suggests that the sample consisted of different chemical substances that reacted with each other, indicating that it was a compound.
