Glucose and fructose are simple sugars with the molecular formula C6HI206• Sucrose, or table sugar, is a complex sugar with molecular formula C12H220I1 that consists of a glucose unit covalently bound to a fructose unit (a water molecule is given off as a result of the reaction between glucose and fructose to form sucrose).
(a) Calculate the energy released as heat when a typical table sugar cube of mass 1.5 g is burned in air.
(b) To what height could you climb on the energy a table sugar cube provides assuming 25 per cent of the energy is available for work?
(c) The mass of a typical glucose tablet is 2.5 g. Calculate the energy released as heat when a glucose tablet is burned in air.
(d) To what height could you climb on the energy a cube provides assuming 25 per cent of the energy is available for work?
