Introduction

Iron (III) oxide, also known as rust, is a chemical compound composed of iron and oxygen. It is a common byproduct of the oxidation of iron and its alloys, particularly in the presence of oxygen and moisture. The production of iron (III) oxide involves a chemical reaction between iron and oxygen, resulting in the formation of the oxide. In this article, we will explore the production of iron (III) oxide from iron and determine the amount of iron (III) oxide that can be produced from a given amount of iron.

The Chemical Reaction

The production of iron (III) oxide involves a chemical reaction between iron and oxygen, which can be represented by the following equation:

4Fe + 3O2 → 2Fe2O3

This equation indicates that four moles of iron react with three moles of oxygen to produce two moles of iron (III) oxide.

Calculating the Amount of Fe2O3 Produced

To determine the amount of iron (III) oxide produced from a given amount of iron, we need to calculate the number of moles of iron (III) oxide produced. Since the reaction is a 4:2 ratio, we can calculate the number of moles of iron (III) oxide produced by dividing the number of moles of iron by 2.

Number of moles of Fe2O3 produced = Number of moles of Fe / 2 = 38.6 moles / 2 = 19.3 moles

Calculating the Mass of Fe2O3 Produced

To calculate the mass of iron (III) oxide produced, we need to multiply the number of moles of iron (III) oxide by its molar mass. The molar mass of iron (III) oxide is given as 159.70 g/mol.

Mass of Fe2O3 produced = Number of moles of Fe2O3 × Molar mass of Fe2O3 = 19.3 moles × 159.70 g/mol = 3085.41 g

Conclusion

In this article, we have explored the production of iron (III) oxide from iron and determined the amount of iron (III) oxide that can be produced from a given amount of iron. We have calculated the number of moles of iron (III) oxide produced by dividing the number of moles of iron by 2, and then calculated the mass of iron (III) oxide produced by multiplying the number of moles of iron (III) oxide by its molar mass. The result shows that 3085.41 grams of iron (III) oxide can be produced from 38.6 moles of iron.
