Question

Mixing of powdered Sulphur with iron filings is a chemical change.

• A. True
• B. False

Answer 1

The correct option is B False

• The changes which can be observed and specified like changes in color, hardness, rigidity, fluidity, density, melting point, boiling point, etc. are the physical changes.
• A chemical change is a change that results in the formation of new chemical substances. It involves the making or breaking of bonds between atoms.
• Here, the mixing of sulfur and iron filings does not alter the chemical composition of a substance, and iron filings can be separated from the mixture by using magnetic separation. Hence it is a physical change.

Hence, the given statement is False.
