About 95-98 percent of alcohol is oxidized to what two substances

D. Water and Carbondioxide

Explanation:

Combustion of organic compounds in the presence of excess Oxygen will liberate carbondioxide (CO2) and water vapour (H2O). This is an exothermic reaction because heat is liberated to the surroundings.

CnH2n+1OH (aq) + (3/2*n) O2 (g) - -> nCO2 (g) + (n + 1) H2O (g)

Addition of Oxygen can also be termed as a redox reaction. In this case, alcohols are oxidised while the Oxygen is reduced.

Example, (propanol)

C3H7OH (aq) + 9/2O2 (g) - -> 3CO2 (g) + 4H2O (g)
