Law of Conservation of Mass: Iron and Chlorine Reaction

In this bell ringer activity from January 28, 2013, students will explore the Law of Conservation of Mass through a chemical reaction involving Iron (III) metal and chlorine gas. The reaction 2Fe + Cl2 → 2FeCl3 demonstrates that mass is conserved. Students will convert moles of the reactants and products into grams, showing 111.6 grams of Fe and 213.0 grams of Cl2 produce 324.6 grams of FeCl3, proving mass equality on both sides of the equation. Join us in learning about reactions and balancing in chemistry!

  2. Bell RingerMonday, 1-28-13 Prove the Law of Conservation of Mass for the following reaction: Iron (III) metal reacts with chlorine gas to produce iron (III) chloride. 2 3 2 Fe + Cl2æ FeCl3 • Convert2 moles of Fe to grams of Fe • = 111.6 grams of Fe • Convert3 moles of Cl2to grams of Cl2 • = 213.0 grams of Cl2 • Convert2 moles of FeCl3to grams of FeCl3 • = 324.6 grams of FeCl3

  3. Bell RingerMonday, 1-28-13 Prove the Law of Conservation of Mass for the following reaction: Iron (III) metal reacts with chlorine gas to produce iron (III) chloride. 2 3 2 Fe + Cl2æ FeCl3 æ • 111.6 g + 213.0 g • 324.6 g Mass is equal on both sides of the equation, thus satisfying the Law of Conservation of Mass.
