WebDefinitions of organic vs inorganic. For historical reasons discussed below, a few types of carbon-containing compounds, such as carbides, carbonates (excluding carbonate esters), simple oxides of carbon (for example, CO and CO 2), and cyanides are considered inorganic.Different forms of pure carbon, such as diamond, graphite, fullerenes, and …

WebNon-methane volatile organic compounds (NMVOCs) are a set of organic compounds that are typically photochemically reactive in the atmosphere—marked by the exclusion of methane. NMVOCs include a large variety of chemically different compounds, such as benzene, ethanol, formaldehyde, cyclohexane, 1,1,1-trichloroethane and acetone. …

WebIn chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as inorganic chemistry.. Inorganic compounds comprise most of the Earth's crust, although the compositions of the deep …

WebIn chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). Ideally, every possible organic compound should …

WebAn element is a chemical substance made up of a particular kind of atom and hence cannot be broken down or transformed by a chemical reaction into a different element, though it can be transmuted into another element through a nuclear reaction.This is because all of the atoms in a sample of an element have the same number of protons, though they …

WebFlüchtige organische Verbindungen (englisch volatile organic compounds, kurz VOC) ist die Sammelbezeichnung für organische, also kohlenstoffhaltige Stoffe, die bei Raumtemperatur oder höheren Temperaturen durch Verdampfen (umgangssprachlich „Verdunsten“) in die Gasphase übergehen, also flüchtig sind. Das Gas Methan, CH 4, ist oft nicht …

WebUV filters are compounds, mixtures, or materials that block or absorb ultraviolet (UV) light. One of the major applications of UV filters is their use as sunscreens to protect skin from sunburn and other sun/UV related damage. After the invention of digital cameras changed the field of photography, UV filters have been used to coat glass discs fitted to camera …

WebA carbonate is a salt of carbonic acid (H 2 CO 3), characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO 2− 3.The word carbonate may also refer to a carbonate ester, an organic compound containing the carbonate group C(=O)(O–) 2.. The term is also used as a verb, to describe carbonation: the process of …
