is this the answer to B )

Question

CH3CH2OH + 3O2 → 2CO2 + 3H2O

In winemaking, the sugars in grapes undergo fermentation by yeast to yield CH3CH2OH and CO2. During cellular respiration, sugar and ethanol are "burned" to water vapor andCO2.

Write a combustion reaction for ethanol. INCLUDE PHYSICAL STATES

I need help with balancing the equation
i think it's
CH3CH2OH + 3O2 → 2CO2 + 3H2O

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!• INCLUDE PHYSICAL STATES

Answer 1

The balanced chemical equation for the fermentation reaction of C6H12O6 is C6H12O6 → 2CH3CH2OH + 2CO2.
The balanced chemical equation for the respiration reaction (combustion) of C6H12O6 is C6H12O6 + 6O2 → 6CO2 + 6H2O.

The formula used to find the standard enthalpy of a reaction is ΔH = ΣΔHf (products) - ΣΔHf (reactants).
