    Notes: Abstract Making use of the enthalpies of formation of the well-established acetic acid and acetic anhydride, the energetics of other carboxylic acid anhydrides (with four or fewer carbons) are discussed. Some of these species are also well known, such as succinic and maleic anhydride. Others are less well known, such as ketene and carbon suboxide and even diatomic carbon and malonic anhydride. Still others are more evasive, such as the classical anhydrides of formic and oxalic acid.

    Notes: Abstract In this study we reconcile three seemingly contradictory assertions regarding sodium chloride. First, gaseous sodium chloride is Coulombically bound and highly ionic. Second, upon pulling the molecule apart atomic sodium and chlorine are produced. This is somewhat surprising; despite the high ionicity of NaCl, since IP(Na) 〉 EA(Cl). Third, heterolytically dissociating NaCl(g) into Na++Cl+ costs more energy than ionizing gaseous Na into Na++e−. Does this violate Coulomb's law since the Na-Cl bond distance in NaCl(g) is greater than the average Na nucleus-valance electron distance?
