This chemical equation illustrates the reaction process between Magnetite (Fe3O4) and hydrogen (H2) to produce iron (Fe) and water (H2O).
-
According to the law of conservation of mass, the total number of moles of the elements in the reactants must equal the total number of moles of the elements in the products. Therefore, the stoichiometric coefficients in front of the substances in the chemical equation must obey the law of conservation of mass.
- Reaction conditions
- The reaction conditions require high temperature and high pressure for the contact between Fe3O4 and H2.
- Reaction process
- When Fe3O4 contacts with H2 at high temperature and pressure, the chemical reaction occurs. In this process, the iron atoms in Fe3O4 will combine with the hydrogen atoms in H2 to form iron and water.
- Phenomena occurred
-
When the reaction occurs, the solid iron (Fe3O4) gradually disappears and forms gray-colored iron (Fe).
-
If the reaction takes place in a test tube or a sealed jar, you can observe the formation of water by watching the gas bubbles appearing in the test tube or jar.
