Examples of these functions are warehousing and shelf stocking. Trade discounts are often combined to include a series of functions, for example 20/12/5 could indicate a 20% discount for warehousing the product, an additional 12% discount for shipping the product, and an additional 5% discount for keeping the shelves stocked.
For example, (C 6 H 5)(CH 3) 2 C + is referred to as a "benzylic" carbocation. The benzyl free radical has the formula C 6 H 5 CH 2 •. The benzyl cation or phenylcarbenium ion is the carbocation with formula C 6 H 5 CH + 2; the benzyl anion or phenylmethanide ion is the carbanion with the formula C 6 H 5 CH − 2.
Sevelamer consists of polyallylamine that is crosslinked with epichlorohydrin. [8] The marketed form sevelamer hydrochloride is a partial hydrochloride salt being present as approximately 40% amine hydrochloride and 60% sevelamer base.
For example, "/C10H16N5O13P3" implies that atoms numbered 1–10 are carbons, 11–15 are nitrogens, 16–28 are oxygens, and 29–31 are phosphorus. [11] Atom connections (prefix: "c"). The atoms in the chemical formula (except for hydrogens) are numbered in sequence; this sublayer describes which atoms are connected by bonds to which other ones.
[5] Vibegron was first discovered by scientists at Merck & Co. Inc. [7] and was later developed in Japan by Kyorin Pharmaceutical Co., Ltd, Kissei Pharmaceutical Co., Ltd, and Urovant Sciences. [8] It was approved for medical use in Japan in September 2018, [8] in the United States in December 2020, [1] [5] [6] and in the European Union in June ...
The solution has 1 mole or 1 equiv Na +, 1 mole or 2 equiv Ca 2+, and 3 mole or 3 equiv Cl −. An earlier definition, used especially for chemical elements , holds that an equivalent is the amount of a substance that will react with 1 g (0.035 oz) of hydrogen , 8 g (0.28 oz) of oxygen , or 35.5 g (1.25 oz) of chlorine —or that will displace ...
MnCl 2 + 2 NaC 5 H 5 → Mn(C 5 H 5) 2 + 2 NaCl. Similar reactions are used in the preparation of the antiknock compound methylcyclopentadienyl manganese tricarbonyl. [3] Manganese chloride is a precursor to organomanganese reagents in organic chemistry. [7] [8] Manganese chloride is mainly used in the production of dry cell batteries.
The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
