This question is about ethanol and ethanoic acid. C C H O H H H ethanol ethanoic acid H H C C H O O H H H Describe the manufacture of ethanol by fermentation. Ethanol can be oxidised by oxygen to form ethanoic acid. Construct the equation for this reaction. A sample of ethanol is heated with ethanoic acid in the presence of concentrated sulfuric acid catalyst. Draw the structure of the product of this reaction. Show all of the atoms and all of the bonds. Ethanol is used as a fuel. C2H5OH + 3O2 3H2O + 2CO2 The complete combustion of one mole of ethanol releases 1350 kJ of energy. A sample of ethanol reacts with excess oxygen to make 0.240 dm3 of carbon dioxide, measured at room temperature and pressure. Calculate the energy released, in kJ, in this reaction. energy released kJ
