Question

1. you are given a container filled with clumps of iron and sand. you can separate the iron from the sand using a magnet. this makes this a ___. a. homogeneous mixture b. compound c. heterogeneous mixture d. solution

Explanation:

A mixture of iron clumps and sand is not chemically combined. Since iron is magnetic and sand is not, using a magnet can separate them. A homogeneous mixture has uniform composition throughout, which this isn't. A compound is a pure - substance made of two or more elements chemically combined. A solution is a homogeneous mixture at the molecular level. This is a heterogeneous mixture as the iron and sand are visibly distinct and can be separated physically.

Answer:

C. heterogeneous mixture
