Description: The article focuses on the fact that the existing systems standard exergies chemical elements are not quite correct thermodynamically, the indicators that are negative values exergies nitrate salts and some other substances. The reason is that the three dominant components of the environment oxygen and nitrogen in the atmosphere and water in the ocean have thermodynamic probability of chemical interaction to form nitrate ion in the ocean. In this paper calculated the equilibrium contents of O2and N2in the atmosphere and the equilibrium concentration of NO3 – -ion in the ocean water, as calculated molar exergies O2and N2 and the air. Shown the air is the holder of the positive exergy and workability, and should not be regarded in exergy applications as ”gift resources”.
