Powdered iron is magnetic, but powdered sulfur is. What occurs when they form a mixture in a beaker at room temperature?

The powdered iron is magnetic, but the powdered sulfur is not. If they both form a mixture in a beaker at room temperature the iron retains its magnetic properties.

Explanation:

Mixing of iron with sulfur, No chemical reaction occurs. This a type of physical reaction so no changes occur.

The iron retains its magnetic properties. If this mixture is heated for a certain degree celsius.

Then it undergoes a chemical reaction. The iron mixed with the sulfur to form iron sulfide (FeS).
