Fundamental Definitions and Core Concepts of Chemistry

Chemistry is established as the scientific discipline focused on the study of matter, including its composition, structure, properties, and the principles governing its behavior. It serves as an intersection for various fields such as physics, biology, environmental science, and engineering to provide a comprehensive understanding of the natural world. This discipline is essential for the development of new technologies, drugs, and materials. A chemical is defined as a substance consisting of atoms or molecules with specific properties and characteristics. A chemical reaction occurs when substances undergo transformation into entirely new substances.

Several specific chemical processes are integral to natural and industrial functions. Fermentation is the process whereby microorganisms convert sugars into alcohols or acids. Photosynthesis involves green plants converting light energy
