Chemistry scope and determination

• Chemistry - A science that deals with matter and the changes it undergoes • From the Greek word “khēmeia (χημεία) (to cast or pour together) and Egyptian word “khēmia” (transmutation of earth)
• Pure Chemistry - Theoretical aspects (“how?”, “why?”, and “what?”) - seeks to define, describe, clarify, and comprehend matter
• Applied Chemistry - looks at how knowledge in Chemistry could be useful - discover practical applications of Chemistry
• Analytical Chemistry – identification, separation, and quantitative determination of the composition of different substances.
• Physical Chemistry – structure of matter, energy changes, and the laws, principles, and theories that explain the transformation of one form of matter to another.
• Inorganic Chemistry – chemistry of elements other than carbon and of their compounds.
• Organic Chemistry – chemistry of compounds containing carbon except for oxides of carbon, carbonates, cyanates, cyanides, thiocyanates, and carbides.
• Biochemistry – chemistry of substances comprising living organisms.
•  Food Chemistry - study of chemical processes and interactions of all biological and non-biological components of foods. This discipline also explores how food products change after undergoing processing techniques and develop ways to either enhance or to prevent those changes.
• Forensic Chemistry - application of chemical methods and principles in the analysis of various substances that might be important or might have been used in the commission of a crime.
•  Biotechnology - the manipulation of living organisms or their components through genetic engineering to produce useful usually commercial products such as pest resistant crops, new bacterial strains, or novel pharmaceuticals.
• gricultural Chemistry - study of chemistry and biochemistry in relation to the agricultural field. It involves development of ways to improve agricultural production, utilization of agricultural products, and other environmental matters.
• Industrial Chemistry - applies chemical and physical procedures for the transformation of natural raw materials and their derivatives into products that are of benefit to humanity.
• Green Chemistry - design of chemical products and processes that reduce or eliminate the use or generation of substances hazardous to humans, animals, plants, and the environment.
• Phytochemistry - studies phytochemicals which are derived from plants for potential applications.
•  Polymer Chemistry - focuses on the chemical synthesis, characterization, and development of polymers and macromolecules with potential on industrial, commercial, or other practical applications.
• Soil Chemistry - studies chemical characteristics of soil and investigates its natural and artificial factors which could lead to soil changes and improvement.
• Soil Chemistry - studies chemical characteristics of soil and investigates its natural and artificial factors which could lead to soil changes and improvement.
•   Toxicology - involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants.
• Geochemistry - applies chemical principles to deepen the understanding of the Earth system and systems of other planets or other celestial bodies.
• Medicinal Chemistry - involves design, chemical synthesis, and development of pharmaceuticals, bio-active molecules, or drugs.
