Typical entries may be:
NaBO3*4H2O, H2Sn(OH)6, (C2H5)2O, Fe0.998O, etc.
The HSC 7.0 database contains more than 25000 species with enthalpy H, entropy S, and heat capacity Cp data; this data is usually based on experimental measurements. The data has been collected from more than 3000 different sources, which may contain typos and misprints. The new HSC Estimates module may be used to identify and filter these errors, because it gives a rough estimate of the H, S, and Cp values based purely on chemical formula.HSC estimates are based on statistical data mining methods, which utilize stoichiometric element amounts, oxidation states, interactions, etc., which may be calculated automatically from the chemical formula. This module is quite easy to use: the user types in the formula and the program gives the formula weight, oxidation states and H, S and Cp estimates
