Question

mechanical separation
what technique would you use if you wanted to separate a mixture of iron and sulfur?
distillation
filtration
evaporation
magnetism

Explanation:

Iron is a magnetic material, while sulfur is not. Magnetism leverages this property difference to pull iron particles out of the mixture, which is an effective mechanical separation method for this pair. Distillation, filtration, and evaporation are used for mixtures involving liquids or dissolved substances, not this solid-solid mixture with magnetic differences.

Answer:

magnetism
