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, a magnet can be used to separate them. A heterogeneous mixture has visibly different parts and components that can be separated by physical means like using a magnet. A homogeneous mixture has a uniform composition throughout and cannot be separated by such simple physical - magnetic means. A compound is a pure substance made of two or more elements chemically combined. A solution is a homogeneous mixture at the molecular level.

Answer:

C. heterogeneous mixture
