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

In saturated organic compounds, all the bonds between carbon atoms are called?

What is the mass of 0.46 mil of mgcl2

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
