    Gibbs's free energy is related to the electromotive force of the cells. When charge flows through the galvanic cell in a reverse reaction, the maximum amount of work is done by the galvanic cell. The amount of this reversible work done by the cell results in a decrease of Gibbs free energy.

    Transition elements (also known as transition metals) are elements that have partially filled d orbitals. IUPAC defines transition elements as an element having a d subshell that is partially filled with electrons, or an element that has the ability to form stable cations with an incompletely filled d orbital.

    The solubility of a solute in a given solvent follows the rule 'Like dissolves like'. Glucose contains five and sucrose contains eight −OH group. These −OH groups form H-bonds with water. As a result of this extensive intermoleeular H-bonding, glucose and sucrose are soluble in water. on the other hand, benzene and cyclohexane do not contain −OH bonds and hence do not form H-bonds with water. Moreover, they are non-polar molecules and hence do not dissolve in polar water molecules.
