The balanced chemical equation for the combustion of ethanol (C₂H₆O) with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O) is:

C₂H₆O (l) + 3O₂ (g) → 2CO₂ (g) + 3H₂O (g)

This equation shows that one mole of ethanol reacts with three moles of oxygen to produce two moles of carbon dioxide and three moles of water.
