TL;DR: In this paper, a new collective edition of the "Selected values of Chemical Thermodynamic Properties," which was issued serially as National Bureau of Standards Technical Notes 270-1 (1965) to 270-8 (1981), was published.
Abstract: : Recommended values are provided for chemical thermodynamic properties of inorganic substances and for organic substances usually containing only one or two carbon atoms. Where available, values are given for the enthalpy of formation, Gibbs energy of formation, entropy, and heat capacity at 298.15 K (25 C), the enthalpy difference between 298.15 and 0 K and the enthalpy of formation at 0 K. All values are given in SI units and are for a standard state pressure of 100 000 pascal. This volume is a new collective edition of 'Selected Values of Chemical Thermodynamic Properties,' which was issued serially as National Bureau of Standards Technical Notes 270-1 (1965) to 270-8 (1981). Values are given for properties of gaseous, liquid and crystalline substances, for solutions in water, and for mixed aqueous and organic solutions. Values are not given for alloys or other solid solutions, fused salts or for substances of undefined composition. Compounds of the transuranium elements are not included. (Author)

TL;DR: In this paper, the Gibbs energy of formation, enthalpy, entropy and heat capacity for all inorganic substances and organic molecules containing not more than two carbon atoms are given.
Abstract: : The tables contain values where known of the enthalpy and Gibbs energy of formation, enthalpy, entropy and heat capacity at 298.15 K (25 C), and the enthalpy of formation at 0 K, for all inorganic substances and organic molecules containing not more than two carbon atoms. In some instances such as metal-organic compounds, data are given for substances in which each organic radical contains one or two carbon atoms. No values are given in these tables for metal alloys or other solid solutions, fused salts, or for substances of undefined chemical composition.

TL;DR: The NBS Circular 500 as discussed by the authors contains tables of values for the standard heats and Gibbs (free) energies of formation, entropies and enthalpies at 298.15 K and 0 K for compounds of vanadium, niobium, tantalum, titanium, zirconium, hafnium, scandium, and yttrium.
Abstract: : Contains tables of values for the standard heats and Gibbs (free) energies of formation, entropies and enthalpies at 298.15 K and heats of formation at 0 K for compounds of vanadium, niobium, tantalum, titanium, zirconium, hafnium, scandium, and yttrium (elements 54-61 in the Standard Order of Arrangement). These tables are a continuation of the comprehensive revision of NBS Circular 500. (Author)

TL;DR: According to Henry's law, the equilibrium ratio between the abundances in the gas phase and in the aqueous phase is constant for a dilute solution as discussed by the authors, and a compilation of 17 350 values of Henry's Law constants for 4632 species, collected from 689 references is available at http://wwwhenrys-law.org
Abstract: Many atmospheric chemicals occur in the gas phase as well as in liquid cloud droplets and aerosol particles Therefore, it is necessary to understand the distribution between the phases According to Henry's law, the equilibrium ratio between the abundances in the gas phase and in the aqueous phase is constant for a dilute solution Henry's law constants of trace gases of potential importance in environmental chemistry have been collected and converted into a uniform format The compilation contains 17 350 values of Henry's law constants for 4632 species, collected from 689 references It is also available at http://wwwhenrys-laworg

TL;DR: In this paper, Tanger and Helgeson proposed correlation algorithms for the prediction of species-dependent parameters in revised equations of state for aqueous ions and electrolytes which can be used together with values at 25°C and 1 bar of the standard partial molal entropies (S0), volumes (V0), and heat capacities (C0p) of the ions to calculate their standard partialmolal thermodynamic properties at pressures and temperatures to 5 kb and 1000°C.
