Hunter Fuller · Answer 1

B: It was a compound

Explanation:

If a chemical reaction was used to separate a sample into its components, then it was a compound. For example, water (H2O, a compound) can be separated by electrolysis into oxygen and hydrogen (its components). the chemical reaction is:

2 H2O - > O2 + 2 H2

Heterogeneous and homogeneous mixtures can be separated by physical ways. Pure substance can be either a compound or an element, so this option is not specific enough to be the correct answer.

Camron Cabrera · Answer 2

C, a compound because it means it was made up of more than one element but, still able to be separated from the other compound (s)
