Glucose and fructose are simple sugars with the molecular formula C6H12O6. Sucrose, or table sugar, is a complex sugar with molecular formula C12H22O11 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 1.5g is burned in air. b.) to what height could you climb on the energy a table sugar cube provides assuming 25 percent of the energy is available for work? c.) the mass of a typical glucose tablet is 2.5g. 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 percent of the energy is available for work?
