is this right?
C2H6O + 3O2 = 2CO2 + 3H2O
In winemaking, the sugars in grapes undergo fermentation by yeast to yield CH3CH2OH and CO2. During cellular respiration, sugar and enthanol are "burned" to water vapor andCO2.
Write a combustion reaction for ethanol.
I need help with balancing the equation
i think it's
C2H6OH(l) + 3O2(g) ---> 2CO2(g) + 3H2O(g)
am I correct?..thanks!•chemistry - paul, Sunday, October 25, 2015 at 3:06pm
looks good to me, except the C2H6OH should be C2H5OH.
I did that, but it said...try again!
then it said HINT:
Start by writing a balanced chemical equation for the fermentation reaction of C6H12O6 and for the respiration reaction (combustion) of C6H12O6...what formula should be used to find the standard enthalpy of a reaction? Use the standard enthalpy of formation values from your textbook when calculating the standard enthalpy of reaction for both fermentation and respiration. thanks!•Chemistry - DrBob222, Monday, October 26, 2015 at 5:30pm
See this site. Zymase is just a catalyst.
chemistry Dr BOB -
According to the site I gave you, the reaction is for the fermentation.
C6H12O6 ==> 2C2H5OH + 2CO2
