enthalpy {Ans: The total heat content of a system at a constant pressure.}solvation {Ans: The process of forming a cage-like network of solvent molecules around a solute in a solution.}solution equilibrium {Ans: When a solute is dissolved in a solvent, it will dissociate until reaching an equilibrium point at which the rate of dissociation equals the rate of precipitation of the solute, regardless of any additional solute introduced into the mixture.}metals {Ans: Elements that are characteristically electropositive, malleable, and ductile. Theses elements tend to be found on the left side of the Periodic Table , are lustrous, and have relatively low ionization energies and electron affinities.}oxidation-reduction half-reaction {Ans: A hypothetical equation showing only the species that is oxidized or reduced in a redox reaction and the correct number of electrons transferred between the species in the complete, balanced equation.}formal charge {Ans: The charge assigned to an atom in a molecule or polyatomic ion, assuming even division of the electrons in a bond. Molecules containing atoms with a lower number of this tend to be more stable than those with a higher number.}
