Lab: Physical and Chemical Changes

Question 4 • FL-2003350-Chemistry 1 Honors Sem 1 - Flex

Which answer below correctly identifies the type of change and the explanation for the separation of the iron with sulfur?

Answer

physical change because even though a color change occured, each solid maintained its original properties, which could be seen as soon as the magnet was applied

physical change because no temperature change was observed, which would be an indicator of chemical change

chemical change because a color change was observed, which indicated that a new substance was formed

chemical change because the results depended on the interaction of two substances

Explanation

Mixing iron and sulfur without heating makes a mixture, so each substance keeps its original properties. A magnet can attract and separate the iron from the sulfur, showing that no new substance formed. A color change alone does not prove a chemical change, and the mixture can be separated physically.
