In winemaking, the sugars in grapes undergo fermentation by yeast to yield ch3ch2oh (ethanol) and co2. during cellular respiration, sugar and ethanol are "burned" to water vapor and co2. (a) using c6h12o6 for sugar, calculate δh o rxn of fermentation and of respiration (combustion). fermentation = kj respiration = kj (b) write a combustion reaction for ethanol. include the physical states of each reactant and product. which releases more heat from combustion per mole of c, sugar or ethanol? sugar ethanol
