When a mixture of iron powder and sulfur powder is heated strongly to...
Explanation:
Heating of Iron and Sulfur Mixture:
- When a mixture of iron powder and sulfur powder is heated strongly, a chemical reaction takes place.
- The iron and sulfur react to form iron sulfide.
Energy Change in the Reaction:
- In this reaction, energy is first absorbed to break the bonds in the reactants (iron and sulfur).
- Then, energy is released when new bonds are formed in the product (iron sulfide).
- This means that the reaction absorbs energy in the beginning and releases energy as it progresses.
Overall Energy Change:
- Therefore, the overall energy change in this reaction involves both absorption and release of energy.
- Initially, energy is absorbed to break the bonds in the reactants, and then energy is released when new bonds are formed in the product.
Conclusion:
- In the reaction between iron and sulfur to form iron sulfide, heat energy is first absorbed to break the bonds in the reactants, and then released as new bonds are formed in the product.

When a mixture of iron and sulphur is heated strongly, they first absorb the energy to get excited. This is followed by the formation of a new compound iron sulfide (FeS)(FeS) with the release of the huge amount of energy in the form of heat and light.
