Trial 2: WebNov 10, 2015 · Explanation: Alcohols react with oxygen in a similar way to hydrocarbons, where they produce carbon dioxide ( CO2) and water ( H 2O ). Therefore, the reaction of the complete combustion of propanol is: C3H 7OH + 9 2O2 → 3CO2 + 4H 2O. Or the equation can be re-written as: 2C3H 7OH +9O2 → 6CO2 + 8H 2O. Answer link.
WebStandard enthalpy of combustion(ΔH ° C) ( Δ H C °) is the enthalpy change when 1 mole of a substance burns (combines vigorously with oxygen) under standard state conditions; it is sometimes called “heat of combustion.”.
