Fe2O3 + CO = Fe + CO2

Balanced Chemical Equation – Solution

Fe2O3 + 3CO → 2Fe + 3CO2

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

Hematite + Carbon Monoxide = Iron + Carbon Dioxide

This is an oxidation-reduction (redox) reaction. CO is a reducing agent, Fe2O3 is an oxidizing agent.

  • 3 CII  6 e  3 CIV (oxidation)
  • 2 FeIII + 6 e  2 Fe0 (reduction)

Reaction Type

Double Displacement (Metathesis)

Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.
