Fe + H2O = Fe3O4 + H2

Balanced Chemical Equation – Solution

3Fe + 4H2O → Fe3O4 + 4H2

The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.

Chemical Reaction Information

This is an oxidation-reduction (redox) reaction. H2O is an oxidizing agent, Fe is a reducing agent.
