Abstract
Chemistry is a branch of natural science and a theoretical-experimental science that actively integrates with biology, geography, mathematics, physics, medicine, agriculture, geology, cosmochemistry, chemical engineering, and other sciences. Chemistry is one of the fundamental disciplines in the system of natural sciences, playing a key role in understanding processes occurring in both living and non-living nature. The importance of chemistry in natural sciences is due to its ability to explain and predict the properties of substances and their reactions, which is necessary for the development of new materials, medicines, and technology. It also contributes to the understanding of biological processes at the molecular level and is significant in ecological and geological research. The theoretical and experimental foundations of chemistry are constantly evolving thanks to progress in the field of instrumental methods of analysis, computer modeling, and interdisciplinary interaction, allowing us to deepen our understanding of chemical processes and expand the boundaries of chemistry's application in natural sciences. The fundamental theoretical foundations of chemistry, experimental research, and technologies have practical significance and form the basis of processes in related sciences. The article summarizes the research of domestic scientists and reviews various methods and technologies based on interdisciplinary connections for the formation of natural science knowledge and production tasks. The main conclusion is the unified integrity of the theoretical foundations of chemical processes and the conceptual system of knowledge.
