Complete oxidation of one mole of ethanol releases how many moles of CO2?
Two
Complete oxidation (combustion) of ethanol converts every carbon atom in the fuel into carbon dioxide and every hydrogen atom into water.
The balanced equation is C2H5OH + 3O2 → 2CO2 + 3H2O.
Ethanol has two carbon atoms, so each molecule (and therefore each mole) of ethanol yields two molecules (two moles) of CO2.
Hence, one mole of ethanol releases two moles of carbon dioxide on complete oxidation.
