Information:  - Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances.  - Acetic acid , systematically named ethanoic acid , is a colourless liquid organic compound with the chemical formula CHCOOH (also written as CHCOH or CHO). When undiluted, it is sometimes called "glacial acetic acid". Vinegar is roughly 39% acetic acid by volume, making acetic acid the main component of vinegar apart from water. Acetic acid has a distinctive sour taste and pungent smell. In addition to household vinegar, it is mainly produced as a precursor to polyvinyl acetate and cellulose acetate. Although it is classified as a weak acid, concentrated acetic acid is corrosive and can attack the skin.  - In chemistry, structural theory explains the large variety in chemical compounds in terms of atoms making up molecules, the order in which atoms are put together in molecules and the electrons that hold them together. According to structural theory, from the structural formula of a molecule it is possible to derive physical and spectroscopic data and to predict chemical reactivity.  - Hermann Kolbe ( Adolph Wilhelm Hermann Kolbe , 27 Sept. 1818 -- 25 Nov. 1884 ) , was a seminal contributor in the birth of modern organic chemistry as Professor at Marburg and Leipzig . Kolbe coined the term synthesis , and contributed to the philosophical demise of vitalism through synthesis of the biologic natural product acetic acid from carbon disulfide , to structural theory via modifications to the idea of `` radicals '' and accurate prediction of the existence of secondary and tertiary alcohols , and to the emerging array of organic reactions through his Kolbe electrolysis of carboxylate salts , the Kolbe - Schmitt reaction in the preparation of aspirin , and the Kolbe nitrile synthesis . After studies with Wöhler and Bunsen , Kolbe was involved with the early internationalization of chemistry through overseas work in London ( with Frankland ) , and rose through the ranks of his field to edit the Journal für Praktische Chemie , to be elected to the Royal Swedish Academy of Sciences , and to win the Royal Society of London 's Davy Medal in the year of his death . Despite these accomplishments and his training a storied next generation of chemists ( including Zaitsev , Curtius , Beckmann , Graebe , Markovnikov , etc. ) , Kolbe is remembered for editing the Journal for more than a decade , where his rejection of Kekulé 's structure of benzene , va n't Hoff 's theory on the origin of chirality , and von Baeyer 's reforms of nomenclature were personally critical and linguistically violent . Kolbe died of a heart attack in Leipzig at age 68 , six years after the death of his wife , Charlotte . He was survived by four children .  - The Parthe is a river in Saxony, Germany, right tributary of the White Elster. Its total length is 60 km. The Parthe originates in northern Saxony, between Colditz and Bad Lausick. It flows northwest through Parthenstein, Naunhof, Borsdorf and Taucha before entering the city of Leipzig. The Parthe joins the White Elster in northwestern Leipzig.  - Carbon (from "coal") is a chemical element with symbol C and atomic number 6. It is nonmetallic and tetravalentmaking four electrons available to form covalent chemical bonds. Three isotopes occur naturally, C and C being stable, while C is a radioactive isotope, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity.  - Élan vital is a term coined by French philosopher Henri Bergson in his 1907 book "Creative Evolution", in which he addresses the question of self-organisation and spontaneous morphogenesis of things in an increasingly complex manner. "Elan vital" was translated in the English edition as "vital impetus", but is usually translated by his detractors as "vital force". It is a hypothetical explanation for evolution and development of organisms, which Bergson linked closely with consciousness - with the intuitive perception of experience and the flow of inner time.  - Hermann Kolbe ("Adolph Wilhelm Hermann Kolbe", 27 September 1818  25 November 1884), was a seminal contributor in the birth of modern organic chemistry. He was a Professor at Marburg and Leipzig. Kolbe coined the term synthesis and contributed to the philosophical demise of vitalism through synthesis of the organic substance acetic acid from carbon disulfide, and also contributed to the development of structural theory. This was done via modifications to the idea of "radicals" and accurate prediction of the existence of secondary and tertiary alcohols, and to the emerging array of organic reactions through his Kolbe electrolysis of carboxylate salts, the Kolbe-Schmitt reaction in the preparation of aspirin and the Kolbe nitrile synthesis. After studies with Wöhler and Bunsen, Kolbe was involved with the early internationalization of chemistry through overseas work in London (with Frankland), and rose through the ranks of his field to edit the . As such, he was elected to the Royal Swedish Academy of Sciences won the Royal Society of London's Davy Medal in the year of his death. Despite these accomplishments and his training, by a storied next generation of chemists (including Zaitsev, Curtius, Beckmann, Graebe, Markovnikov, etc.), Kolbe is remembered for editing the "Journal" for more than a decade, where his rejection of Kekulé's structure of benzene, van't Hoff's theory on the origin of chirality and von Baeyer's reforms of nomenclature were personally critical and linguistically violent. Kolbe died of a heart attack in Leipzig at age 68, six years after the death of his wife, Charlotte. He was survived by four children.  - Berlin is the capital and the largest city of Germany as well as one of its constituent 16 states. With a population of approximately 3.5 million people, Berlin is the second most populous city proper and the seventh most populous urban area in the European Union. Located in northeastern Germany on the banks of rivers Spree and Havel, it is the centre of the Berlin-Brandenburg Metropolitan Region, which has about 6 million residents from more than 180 nations. Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. Around one-third of the city's area is composed of forests, parks, gardens, rivers and lakes.  - The Kolbe electrolysis or Kolbe reaction is an organic reaction named after Hermann Kolbe. The Kolbe reaction is formally a decarboxylative dimerisation of two carboxylic acids (or carboxylate ions) The overall general reaction is:  - Organic chemistry is a chemistry subdiscipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. Study of structure includes many physical and chemical methods to determine the chemical composition and the chemical constitution of organic compounds and materials. Study of properties includes both physical properties and chemical properties, and uses similar methods as well as methods to evaluate chemical reactivity, with the aim to understand the behavior of the organic matter in its pure form (when possible), but also in solutions, mixtures, and fabricated forms. The study of organic reactions includes probing their scope through use in preparation of target compounds (e.g., natural products, drugs, polymers, etc.) by chemical synthesis, as well as the focused study of the reactivities of individual organic molecules, both in the laboratory and via theoretical (in silico) study.  - Cellulose acetate is the acetate ester of cellulose. It was first prepared in 1865. Cellulose acetate is used as a film base in photography, as a component in some coatings, and as a frame material for eyeglasses; it is also used as a synthetic fiber in the manufacture of cigarette filters and playing cards. In photographic film, cellulose acetate replaced nitrate film in the 1950s, being far less flammable and cheaper to produce.  - Sweden, officially the Kingdom of Sweden (Swedish: ), is a Scandinavian country in Northern Europe. It borders Norway to the west and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund. At , Sweden is the third-largest country in the European Union by area, with a total population of 10.0 million. Sweden consequently has a low population density of , with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas.  - In silico (literally Latin for "in silicon", alluding to the mass use of silicon for semiconductor computer chips) is an expression used to mean "performed on computer or via computer simulation." The phrase was coined in 1989 as an allusion to the Latin phrases "in vivo", "in vitro", and "in situ", which are commonly used in biology (see also systems biology) and refer to experiments done in living organisms, outside of living organisms, and where they are found in nature, respectively.  - Vinegar is a liquid consisting of about 520% acetic acid (CHCOOH), water, and other trace chemicals, which may include flavorings. The acetic acid is produced by the fermentation of ethanol by acetic acid bacteria. Vinegar is now mainly used as a cooking ingredient, or in pickling. As the most easily manufactured mild acid, it has historically had a great variety of industrial, medical, and domestic uses, some of which (such as its use as a general household cleaner) are still commonly practiced today.  - The Royal Swedish Academy of Sciences or "Kungliga Vetenskapsakademien" is one of the Royal Academies of Sweden. It is an independent, non-governmental scientific organisation which takes special responsibility for the natural sciences and mathematics, but endeavours to promote the exchange of ideas between various disciplines.  - Vitalism is a discredited scientific hypothesis that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things". Where vitalism explicitly invokes a vital principle, that element is often referred to as the "vital spark", "energy" or "élan vital", which some equate with the soul.  - The electron is a subatomic particle, symbol or , with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, "". As it is a fermion, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle. Like all matter, electrons have properties of both particles and waves: they can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a larger De Broglie wavelength for a given energy.  - An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are very small; typical sizes are around 100 picometers (a ten-billionth of a meter, in the short scale).  - Leipzig is the largest city in the federal state of Saxony, Germany. With a population of 570,087 inhabitants (1,001,220 residents in the larger urban zone) it is Germany's tenth most populous city. Leipzig is located about southwest of Berlin at the confluence of the White Elster, Pleisse and Parthe rivers at the southern end of the North German Plain.
