Which answer below correctly identifies the type of change and the explanation for the separation of the iron with sulfur?
A. physical change because even though a color change occurred, each solid maintained its original properties, which could be seen as soon as the magnet was applied
B. physical change because no temperature change was observed, which would be an indicator of chemical change
C. chemical change because a color change was observed, which indicated that a new substance was formed
D. chemical change because the results depended on the interaction of two substances
Answer (2)
The separation of iron from sulfur is identified as a physical change because no chemical reaction occurs. Iron retains its properties, allowing it to be separated from sulfur using a magnet. Therefore, the original components of the mixture can be recovered without changing their chemical identities. ;
The separation of iron from sulfur is a physical change because no chemical reaction occurs, allowing for the iron to be separated using a magnet while retaining its properties. Therefore, the correct choice is option A. This process ensures that both substances can be recovered without any alteration to their chemical identities.
