CH3OH + O2 = CO2 + H2O

Balanced Chemical Equation – Solution

2CH3OH + 3O2 → 2CO2 + 4H2O

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

Methanol + Dioxygen = Carbon Dioxide + Water

This is an oxidation-reduction (redox) reaction. CH3OH is a reducing agent, O2 is an oxidizing agent.

  • 2 C-II  12 e  2 CIV (oxidation)
  • 6 O0 + 12 e  6 O-II (reduction)

Reaction Type


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