Which molecule release more energy per gram during complete combustion, Glucose (C6H12O6) or hexanoic acid (C6H14O2)? Please explain!
Homework Answers
Hexanoic acid (C6H14O2)
In hydrocarbons like Glucose and Hexanoic acid, energy is stored in
C-C bonds and C-H bonds. When these compounds are combusted, the
Carbon atoms and Hydrogen atoms become Oxidised to H2O and CO2.
However, in Glucose, more of the C-H bonds are already Oxidized,
which means Glucose would release less energy on combustion than
Hexanoic acid would.

The complete combustion of salicylic acid releases 21.90 kJ of energy per gram of salicylic acid. In a particular bomb calorimeter (initially at room temperature), the combustion of 0.2038 g of salicylic acid, in the presence of excess oxygen, causes the temperature of the calorimeter to rise by 2.94 °C. When a 0.2172-g sample of an unknown organic substance is similarly burned in the same calorimeter, the temperature rises by 4.58 °C. What is the energy of combustion per unit...
