Question:
how is mixing of iron and sulphur a physical and chemical change on heating ? explain giving reason
Answer:
When iron filings and sulfur powder are combined, their inherent properties remain unchanged. Consequently, the amalgamation of iron and sulfur is classified as a physical change.
However, upon heating the mixture of iron filings and sulfur powder, they undergo chemical reactions, resulting in the production of ferrous sulfide.
Thus, the act of heating the combination of iron filings and sulfur powder is considered a chemical change.
The application of strong heat to a mixture of iron filings and sulfur powder will yield ferrous sulfide.
