Use bond enthalpies to estimate a) the enthalpy of the anaerobic breakdown of glucose to lactic acid in cells that are starved of oxygen, C6H12O6(aq) → 2 CH3CH(OH)COOH(aq), b) the enthalpy of combustion of glucose. Ignore the contributions of enthalpies of fusion and vaporization.

#1. Estimate ΔH for the reaction using bond dissociation energies. Give your answer in kcal. C6H12O6 has five C−C bonds, seven C−H bonds, seven C−O bonds, and five O−H bonds. #2. Is the reaction exothermic or endothermic? #3. The following equation shows the conversion of aluminum oxide (from the ore bauxite) to aluminum: 2Al2O3(s)→4Al(s)+3O2(g), ΔH = +801.0 kcal ----> a. Is the reaction exothermic or endothermic?

Estimate the time needed for a glycine molecule (see Table 13?4 in the textbook) to diffuse a distance of 29 ?m in water at 20 ?C if its concentration varies over that distance from 1.05 mol/m3 to 0.43 mol/m3 Compare this "speed" to its rms (thermal) speed. The molecular mass of glycine is about 75 u
