Use bond enthalpies and mean bond enthalpies to estimate (a) the enthalpy of the anaerobic breakdown of glucose to lactic acid in cells that are starved of O2, C6H12O6(aq) → 2 CH3CH(OH) COOH(aq), and (b) the enthalpy of combustion of glucose (Ignore the contributions of enthalpies of fusion and vaporization). NOTE: When using bond enthalpies alone to estimate reaction enthalpies, it is not possible to include condensed phase interactions, so the estimates are for gas-phase reactions.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
