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.
- 8 HI + 8 e– → 8 H0 (reduction)
- 3 Fe0 – 8 e– → 3 Fe8/3 (oxidation)
