Iron filings are placed in powdered sulfur. Both iron and sulfur are elements. The iron and sulfur are stirred together until they are evenly mixed. Then, the iron filings are removed from the sulfur with the use of a magnet. What type of substance is the iron and sulfur combination?A A pure pure substancesubstanceA A compound compound A A solutionsolutionA A mixturemixture

A mixture

Explanation:

A pure substance must have only one element . But it contains two types of elements . One is iron and the other is sulphur . So it is not pure substance .

A compound must have at least two element joined with chemical bond . So they are not easily separable . But here iron and sulphur are easily separated . so it is not a compound.

It is not a solution because a solution must have two elements out of which one should be in liquid form . But here none of the elements involved ie iron or sulphur is in liquid form so it is not solution .

Hence , it is a mixture.
