One measure of the organic content of wateris chemical oxygen demand (COD). In the COD test, organic matter is oxidized with dichromate, Cr2O72-, at low pH to CO2and the dichromate is reduced to Cr 3.Write the balanced overall reaction for the oxidation of ethanol (CH3CH2OH) in the COD test.

If 22.5 liters of oxygen reacted with excess of hydrogen, how many liters of water vapor could be produced?
