Is it possible to epistemologically reduce chemistry to physics according to E. Nagel?

The purpose of the article was an epistemological analysis of the principle of reduction in chemistry using the example of the reducibility of chemistry to physics. For this purpose, the E. Nagel reduction model was used, which set the course of research in two directions: to identify the connection between the concepts of these sciences and the possibility of deductive deduction of the concepts of chemistry from physics. The research methodology based on the application of the principles of historical and logical connection, a systematic approach, formal logical methods, a comparative method and interpretation. The problem of reduction considered in the context of the history and logic of the development of philosophy and natural sciences. A systematic approach to this problem made it possible to identify three types of reduction - conceptual, quantitative and ontological, and established links between them and with E. Nagel's model. To study the conceptual reduction, the semantic content of the concepts of chemistry and physics was established, for which formal logical methods, methods of comparison and interpretation were used, which revealed the uniqueness of the language of chemistry and the peculiarity of its conceptual systems, which are not fully expressible in the formal mathematical language of physics. Conceptual reduction entails ontological reduction due to a different interpretation of the concepts of chemistry and the uniqueness of quantum methodology. The concepts of chemistry also have a quantitative content that facilitates quantitative reduction, but it is limited due to the reduction of chemistry to an axiomatic system using deduction, which falls under the scope of Godel's incompleteness theorem. Quantitative reduction in chemistry correlated with E. Nagel's correspondence rule, which is the population matrix in quantum mechanics, which interprets a chemical bond and a molecule in a different way. Therefore, complete uniformity of theory dictionaries never achieved, as believed E. Nagel. Reduction is a simplification of chemistry, since there are linguistic and conceptual barriers between chemistry and physics and limitations of deduction, therefore, E.Nagel's model meets objections. The author declares no conflicts of interests.
