Question

Consider the anaerobic fermentation of glucose to ethanol by yeast. Glucose (C6H12O6) is converted into yeast, ethanol (C2H5OH),
the by-product glycerol (C3H8O3), carbon dioxide, and water. An empirical chemical formula for yeast can be taken as
CH1.74N0.200.45 (Shuler and Kargi, 2002). Assuming ammonia (NH3) is the nitrogen source, we can write the following empirical
chemical equation to describe the fermentation:
C6H12O6 + a NH3 →b CH1.74N0.200.45 (yeast) + CC2H5OH + d C3H8O3 + CO2 + H2O
Suppose, we found that 0.21 moles of glycerol was formed for each mole of ethanol produced and 0.13 moles of water were formed for
each mole of glycerol. Determine the stoichiometric coefficients, which are the letters a, b, c, d, e, and f in front of the chemical formulas
in the above equation. Remember that the stoichiometric coefficients need to be determined so that the total number of carbon,
hydrogen, oxygen, and nitrogen atoms are the same on each side of the equation.
Label your solution below as follows: a =
b =
=

The name carbohydrate comes from the fact that many simple sugars have chemical formulae that look like water has simply been added to carbon. (The suffix hydrate from the Greek word hydor ("water") means "compound formed by the addition of water.") The actual chemical structure of carbohydrates doesn't look anything like water molecules bonded to carbon atoms (see sketch at right). But it is nevertheless possible to chemically extract all the hydrogen and oxygen from many simple carbohydrates as water, leaving only carbon behind. If you search the Internet for "reaction of sulfuric acid and sugar" you will find some impressive videos of this. Suppose you had (200. g) of ordinary table sugar, which chemists call sucrose, and which has the chemical formula C12H₂2011. Calculate the maximum mass of water you could theoretically extract.
