File Name: common names of chemical compounds and their uses .zip
The atoms in all substances that contain multiple atoms are held together by electrostatic interactions—interactions between electrically charged particles such as protons and electrons. Electrostatic attraction between oppositely charged species positive and negative results in a force that causes them to move toward each other, like the attraction between opposite poles of two magnets.
A chemical nomenclature is a set of rules to generated systematic names for chemical compounds. A third publication, known as the Green Book ,  describes the recommendations for the use of symbols for physical quantities in association with the IUPAP , while a fourth, the Gold Book ,  contains the definitions of many technical terms used in chemistry. These "color books" are supplemented by shorter recommendations for specific circumstances that are published periodically in the journal Pure and Applied Chemistry. The primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single substance. A less important aim is to ensure that each substance has a single name, although a limited number of alternative names is acceptable in some cases.
Sodium Na , chemical element of the alkali metal group Group 1 [Ia] of the periodic table. Sodium is a very soft silvery-white metal. Sodium is the most common alkali metal and the sixth most abundant element on Earth, comprising 2. It occurs abundantly in nature in compounds , especially common salt —sodium chloride NaCl —which forms the mineral halite and constitutes about 80 percent of the dissolved constituents of seawater. In Sir Humphry Davy became the first to prepare sodium in its elemental form, applying electrolysis to fused sodium hydroxide NaOH.
In this list Compound name, Chemical formula of the compound and its uses are given. Uses: Non-prescription drug for relief from acid indigestion and heartburn. Also considered a calcium supplement.. Uses: Used to season food during food preparation and at the table , also used in the past as a method of food preservation. Uses: natural gas, fuel also called Marsh Gas.
Ether , any of a class of organic compounds characterized by an oxygen atom bonded to two alkyl or aryl groups. Ethers are similar in structure to alcohols , and both ethers and alcohols are similar in structure to water. In an alcohol one hydrogen atom of a water molecule is replaced by an alkyl group, whereas in an ether both hydrogen atoms are replaced by alkyl or aryl groups. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points.
If you keep an eye on the latest trend followed by SSC for General Awareness questions , you would notice that Science facts are covering major portions of it. To help you quickly take a look at List of Chemical Formulas and their Common Names , we are providing you in this article. To help you attempt the chemistry questions without any glitches, we are sharing with you a detailed list of Chemical Formulas and their Common Names. Chemical formulas are expressions which state the number and types of atoms present in a molecule of a substance. Before moving ahead have a look at the Chemical compounds.
The common names and formulas of chemical compounds is a very relevant area of study for every competitive exam including SSC and it is important for the aspirants to develop a fair idea on this subject. In this article, we are discussing the following topics.
In traditional medicine, there has been a great deal of research on the effects exhibited by medicinal materials. To study the effects, resources that can systematically describe the chemical compounds in medicinal materials are necessary. In recent years, numerous databases on medicinal materials and constituent compounds have been constructed. However, because these databases provide differing information and the sources of such information are unclear or difficult to verify, it is difficult to decide which database to use. Moreover, there is much overlapping information. The aim of this study was to construct a database of medicinal materials and chemical compounds in Northeast Asian traditional medicine TM-MC , for which medicinal materials are listed in the Korean, Chinese, and Japanese pharmacopoeias and information on the compound names of medicinal materials can easily be confirmed online.
Телефонистка нервно проглотила слюну. - На этой машине нет автоматического определителя номера, сэр. Я позвоню в телефонную компанию. Я уверена, что они смогут сказать.
Стратмор сурово посмотрел на. - Этот алгоритм создал один самых блестящих умов в криптографии. Сьюзан пришла в еще большее смятение: самые блестящие умы в криптографии работают в ее отделе, и уж она-то наверняка хоть что-нибудь услышала бы об этом алгоритме. - Кто? - требовательно сказала .
Нуматака хорошо понимал, что эти поклоны вовсе не свидетельствует об их любви к нему, они - всего лишь знак вежливости, которую японские служащие проявляют по отношению даже к самым ненавистным начальникам. Нуматака проследовал прямо на коммутатор компании.
Ну и порядки. Звук мотора, похожий на визг циркулярной пилы, заставил его повернуться. Парень крупного сложения и прильнувшая к нему сзади девушка въехали на стоянку на стареньком мотоцикле Веспа-250. Юбка девушки высоко задралась от ветра, но она не обращала на это ни малейшего внимания. Беккер рванулся к .
Покажите мне. Чатрукьян заколебался. - Я не могу.
