Which one of the following equations is the balanced chemical equation for the given reaction? Fe + H2O → Fe3O4 + H2
- A.Fe + 4H2O → Fe3O4 + H2
- B.3Fe + H2O → Fe3O4 + 2H2
- C.3Fe + 4H2O → Fe3O4 + 4H2
- D.3Fe + 4H2O → Fe3O4 + H2
Show answer
Only this equation has the same number of iron, hydrogen and oxygen atoms on both sides. Iron reacts with steam to form iron(II,III) oxide and hydrogen gas.
