Chemistry is the scientific study of compounds, their composition, structure, properties and reactions. Compounds are chemical substances formed by chemical bonds between two or more identical molecules. It also studies the bonding responsible for the formation of these compounds. The factors of energy and entropy are important in the study of chemical processes. Chemical substances are classified on the basis of their structure, phase and composition. They can be analyzed using the tools of spectroscopy and chromatography. Chemistry is divided into a number of significant sub-disciplines such as analytical chemistry, biochemistry, inorganic chemistry, organic chemistry, etc. There has been rapid progress in this field and its applications are finding their way across multiple industries such as extraction of metals from ores, fermentation of beer and wine, manufacture of glass and alloys, etc. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the field of chemistry. The data presented herein also explores some of the most innovative concepts and elucidates the unexplored aspects of this discipline. This book will serve as a reference to chemical engineers, researchers, experts and students.
