This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
Elemental chlorine has since served a continuous function in topical antisepsis (wound irrigation solutions and the like) and public sanitation, particularly in swimming and drinking water. [18] Chlorine gas was first used as a weapon on April 22, 1915, at the Second Battle of Ypres by the German Army.
Nascent state or in statu nascendi (Lat. newly formed moiety: in the state of being born or just emerging), is an obsolete theory in chemistry.It refers to the form of a chemical element (or sometimes compound) in the instance of their liberation or formation.
The standard state of a material (pure substance, mixture or solution) is a reference point used to calculate its properties under different conditions.A degree sign (°) or a superscript Plimsoll symbol (⦵) is used to designate a thermodynamic quantity in the standard state, such as change in enthalpy (ΔH°), change in entropy (ΔS°), or change in Gibbs free energy (ΔG°).
Such reagents include cobalt trifluoride, chlorine trifluoride, and iodine pentafluoride. [4] The method electrochemical fluorination is used commercially for the production of perfluorinated compounds. It generates small amounts of elemental fluorine in situ from hydrogen fluoride. The method avoids the hazards of handling fluorine gas.
Liebig treated anhydrous ethanol with dry chlorine gas. [3] Chloral is produced commercially by the chlorination of acetaldehyde in the presence of hydrochloric acid, producing chloral hydrate. Ethanol can also be used as a feedstock. This reaction is catalyzed by antimony trichloride: H 3 CCHO + 3 Cl 2 + H 2 O → Cl 3 CCH(OH) 2 + 3 HCl
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
CL2 may refer to: . Chlorine gas, Cl 2; the Clausen function of order 2, Cl 2; the Clifford algebra on , (); CAS latency 2, a rating of computer memory; Google Calendar, a time-management web application (from a URL fragment used in early versions)
