select the correct answer. a chemist divides a large sample of a mixture into three smaller portions. each of these portions contains different ratios of the component substances that make up the mixture. which description best fits the mixture? a. compound b. element c. heterogeneous mixture d. homogeneous mixture e. pure substance

Answer

Brief Explanations:

A compound has a fixed ratio of elements. An element is a pure substance made of one - type of atom. A pure substance has a definite and constant composition. A homogeneous mixture has a uniform composition throughout. A heterogeneous mixture has different compositions in different parts. Since the three smaller portions of the sample have different ratios of component substances, it is a heterogeneous mixture.

Answer:

C. heterogeneous mixture
