Chemistry is a natural science that includes the structure, properties and transformation of chemical substances. All materials and substances consist of atoms, molecules or both. Chemical reactions are processes in the electron shells of atoms, molecules and ions.
Chemistry in everyday life
Chemistry is everywhere. Chemical reactions in everyday life occur, for example, when cooking, baking or baking. There are complex transformations that occur here that lead, for example, to the typical taste of food. During the body’s own decomposition process, food is chemically broken down into its components and converted into energy. The best chemical reaction to observe is the burning or boiling of water.
Hair dyes, internal combustion engines, cell phone displays, detergents, fertilizers, medicines, disinfectants are further examples of chemical applications in daily life.
Importance of chemistry for economy and society
Chemistry deals with the properties of elements and compounds chemically and provides methods for the synthesis of new compounds and measurement methods for deciphering the chemical composition of unknown substances.
The type of composition ultimately determines the chemical and physical properties of the substance and thus makes chemistry a comprehensive science.
Progress in various sub-areas of chemistry is usually an indispensable prerequisite for acquiring new knowledge in other disciplines, particularly in the fields of biology and medicine as well as in the fields of physics and engineering.
Newly discovered reactions or substances can replace old reactions or substances, which is why they are also of great importance in science and industry.
For medicine, chemistry is essential in the search for new drugs and the manufacture of drugs.
The engineering sciences often look for materials that are tailored to the application (lightweight materials for aircraft construction, durable and flexible building materials, high-purity semiconductors). Their synthesis is one of the tasks of chemistry
