Question
Consider the combustion of a mole of fructose, given by the reaction
C6H12O6 + 6O2 6CO2 + 6H2O.
This is the net reaction that generates the energy one would get from drinking a sugary drink.
(a) Calculate the enthalpy of combustion H.
(b)The atomic weight of fructose is about 180 u. A typical can of soda contains about 40 grams of sugar, which we’ll assume is fructose since most things use high fructose corn syrup. Use this information and the result of the previous part to calculate the amount of energy released in the combustion of the sugar in one soda can (i.e., 40 grams of fructose). Compare this to the energy needed to lift 60 kilograms a distance of 10 meters (representing, perhaps, a set on the bench press at the gym...).
