Example 3
mediumExplain why mixing iron filings and sulfur powder produces a mixture, but heating them together produces a compound (). How could you distinguish between the two?
Solution
- 1 When mixed without heating, iron and sulfur retain their individual properties — iron can be removed with a magnet, and sulfur can be dissolved in carbon disulfide. This is a mixture.
- 2 When heated, they undergo a chemical reaction (), forming a new substance that is non-magnetic and has different properties from either element.
Answer
This classic experiment demonstrates the difference between physical mixing and chemical combination. The compound FeS has properties entirely different from iron and sulfur, confirming that a chemical change occurred.
About Mixture
A physical combination of two or more substances that are not chemically bonded, retain their individual properties, exist in variable proportions, and can be separated.
