A mixture of iron filings and sulfur can easily be separated by which of the following methods?

• A. Distillation
• B. Evaporation
• C. Filtration
• D. Using a magnet

Answer: (D)

Verified step by step guidance

1. Identify the physical properties of the components in the mixture: iron filings are magnetic, while sulfur is not magnetic and is a non-metal.
2. Understand that distillation and evaporation are separation techniques used primarily for mixtures of liquids or solutions, which do not apply here since both iron and sulfur are solids.
3. Recognize that filtration separates solids from liquids or separates solids based on particle size, but it does not separate solids based on magnetic properties.
4. Recall that magnetic separation is a technique that uses a magnet to attract magnetic materials (like iron filings) and separate them from non-magnetic materials (like sulfur).
5. Conclude that using a magnet is the most effective method to separate a mixture of iron filings and sulfur because it exploits the magnetic property of iron.
