Recipe for Iron Sulfide

5 grams Iron Filings (Fe)
5 grams Sulfur (S)
HEAT (from Bunsen Burner)

Add iron filings and sulfur together, and place in test tube. Add heat from the Bunsen burner. Simmer for several minutes. Let reaction occur in a fume hood to prevent the aroma from going around the whole school.

Here is a view of what happened as our mixture of Iron and Sulfur became Iron Sulfide:



Some questions for the Crazy 8s:

1. What were some signs that a chemical change took place? (What did you observe as the mixture in the test tube was heated?) Be descriptive!
2. Did the properties of the original components change when the new substance was formed? How? Which ones?
3. The mass of your new substance was less than the mass of the individual components that went into the reaction. However, in a chemical reaction, matter is neither created nor destroyed. What explains the change in mass?
