Abnormal Molar Mass
A molar mass value obtained from colligative measurements that differs from the true value because the solute associates or dissociates.
Organic ChemistryAldol Condensation

Foundations of ChemistryAtomic Mass Unit
A mass unit defined as exactly one twelfth the mass of a free, unbound carbon-12 atom in its ground state.
Atomic Structure & PeriodicityAtomic Orbital
A mathematical function describing the region around a nucleus where an electron of given energy is most likely to be found.
States of Matter & Gas LawsAverage Kinetic Energy
The mean translational kinetic energy of the particles in a sample, dependent only on absolute temperature.

States of Matter & Gas LawsCharles's Law
At constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature.
Inorganic & Coordination ChemistryChelate Effect
The greater stability of a complex containing a multidentate ligand compared with one containing equivalent monodentate ligands.
Foundations of ChemistryChemical Formula
A symbolic notation that states which elements a substance contains and in what proportions, using element symbols and subscripts.

Strong adsorption in which actual chemical bonds form between the adsorbate and the surface.
Chemical Kinetics & CatalysisCollision Frequency
The number of collisions occurring per unit volume per unit time in a reacting mixture.
States of Matter & Gas LawsCompressibility Factor
The ratio of the actual molar volume of a gas to that predicted by the ideal gas law.
States of Matter & Gas LawsCondensation
The change of a substance from the gaseous to the liquid state, accompanied by the release of latent heat.
Chemical Bonding & Molecular StructureCovalent Bond
A bond formed when two atoms share one or more pairs of electrons so that both achieve a stable configuration.
