Asample of concrete contains cement, gravel, crushed rocks, sand, and water. each of these contains different metals and minerals and hence has different colors and different properties. which term or terms could be used to describe this sample of concrete? a. mixtureb. heterogeneous mixturec. homogeneous mixtured. solutione. pure chemical substancef. compoundg. element

The answer to your question is a heterogeneous mixture

Explanation:

The Matter is classified as Pure substances and Mixtures

Pure substances are elements or compounds which are not mixed with more substances.

Mixtures are several elements or compounds together, mixtures can be homogeneous or heterogeneous.

Homogeneous mixtures are when the different components can be identified.

Heterogeneous mixtures are when the different components can be identified just by looking at the mixture.

In concrete we can identify the different components like gravel, sand, crushed rocks, etc, so concrete is a heterogeneous mixture.
