Ammonium perchlorate ("AP") is an inorganic compound with the formula NH 4 ClO 4.It is a colorless or white solid that is soluble in water. It is a powerful oxidizer.Combined with a fuel, it can be used as a rocket propellant called ammonium perchlorate composite propellant.
AP – alkali-polymer; APD – application for permit to drill; API – American Petroleum Institute: organization which sets unit standards in the oil and gas industry °API – degrees API (gravity of oil) APPRE – appraisal report; APS – active pipe support; APWD – annular pressure while drilling (tool) [5] ARACL – array acoustic log
The Chemistry, Biology, Physics and Design Technology was last updated for first teaching in September 2014, with syllabus updates (including a decrease in the number of options), a new internal assessment component similar to that of the Group 5 (mathematics) explorations, and "a new concept-based approach" dubbed "the nature of science". A ...
The CDU is often referred to as the atmospheric distillation unit because it operates at slightly above atmospheric pressure. [1] [2] [41] Below is a schematic flow diagram of a typical crude oil distillation unit. The incoming crude oil is preheated by exchanging heat with some of the hot, distilled fractions and other streams.
Infrared spectroscopy is a simple and reliable technique widely used in both organic and inorganic chemistry, in research and industry. It is used in quality control, dynamic measurement, and monitoring applications such as the long-term unattended measurement of CO 2 concentrations in greenhouses and growth chambers by infrared gas analyzers.
It is intended to be used for applications in metabolomics, clinical chemistry, biomarker discovery and general education. The database is designed to contain or link three kinds of data: Chemical data, Clinical data and; Molecular biology/biochemistry data.
Chromatography, pronounced / ˌ k r oʊ m ə ˈ t ɒ ɡ r ə f i /, is derived from Greek χρῶμα chrōma, which means "color", and γράφειν gráphein, which means "to write".". The combination of these two terms was directly inherited from the invention of the technique first used to separate biological pigme
The CDC described synthetic cannabinoid overdoses between 2010 and 2015 and of 277 drug overdose patients who reported synthetic cannabinoid as the sole agent, 66.1% reported problems in the central nervous system (e.g., agitation, coma, toxic psychosis), 17% reported cardiovascular problems (e.g., tachycardia, bradycardia), 7.6% reported ...
