help!!!!
is this the answer to B )
C2H5OH(liq)+ 3O2(g) --> 2CO2(g) +3H2O(liq)
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
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.
comment:
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 DR BOB - Anonymous, Tuesday, October 27, 2015 at 7:03pm
not balanced.
C2H5OH+ 3O2 >>> 2CO2 + 3H2O
To properly balance the combustion reaction for ethanol (C2H5OH), we need to make sure that the number of each element is the same on both sides of the equation.
Let's start with the carbon (C) atoms. On the left-hand side, we have 2 carbon atoms from C2H5OH, and on the right-hand side, we have 2 carbon atoms from CO2. So far, the number of carbon atoms is balanced.
Next, let's move on to the hydrogen (H) atoms. On the left-hand side, we have 6 hydrogen atoms from C2H5OH, and on the right-hand side, we have 6 hydrogen atoms from H2O. The number of hydrogen atoms is also balanced.
Finally, let's check the oxygen (O) atoms. On the left-hand side, we have 3 oxygen atoms from O2, and on the right-hand side, we have 4 oxygen atoms from CO2 and 3 oxygen atoms from H2O. The total number of oxygen atoms is 7, which is not equal on both sides.
To balance the oxygen atoms, we can add a coefficient in front of the O2 on the left-hand side. By adding a coefficient of 7, we will have 7 oxygen atoms on both sides of the equation:
C2H5OH + 7O2 → 2CO2 + 3H2O
Now the equation is balanced with respect to the number of carbon, hydrogen, and oxygen atoms.
