Question

Use the chemical equation to complete the activity.

4Fe + 3O2 → 2Fe2O3

Iron (Fe) reacts with oxygen (O2) to form iron oxide. A scientist adds 15.4 grams of Fe to 3.6 grams of O2 to start the reaction. All of the iron and oxygen react to form iron oxide. Explain in detail how you can determine how many grams of iron oxide will be produced.
Use the law of conservation of mass in the explanation.

To determine how many grams of iron oxide will be produced, you need to calculate the number of moles of each reactant. Then, using the stoichiometry of the balanced chemical equation, determine the mole ratio between iron and iron oxide. Finally, convert the moles of iron oxide to grams using its molar mass. The law of conservation of mass states that the total mass of the reactants must equal the total mass of the products, so the calculated mass of iron oxide should be consistent with this principle.
