What is the correct balanced chemical equation for the reaction of iron with water (steam)?

Subject: General Science

Topic: Chemical Reactions and Equations

Options:

1. Option A: Fe + H2O → FeO + H2
2. Option B: 2Fe + 3H2O → Fe2O3 + 3H2
3. Option C: 3Fe + 4H2O → Fe3O4 + 4H2
4. Option D: Fe + 2H2O → Fe(OH)2 + H2

Correct Answer:

Option C: 3Fe + 4H2O → Fe3O4 + 4H2

Explanation:

The text details the step-by-step balancing of this reaction, concluding with the balanced equation: 3Fe(s) + 4H2O(g) → Fe3O4(s) + 4H2(g). This equation satisfies the law of conservation of mass, with equal numbers of each atom on both sides.
