Pàgina 14 - English name) ; or when the names of two or more elements begin with the same letter, two letters are used as the symbol, one of which is always the first letter of the name of the element.
Pàgina 12 - If we take a salt* to be the product of the mutual action of an acid and a metal or base upon each other, normal salts are obtained by exchanging the whole of the replaceable hydrogen of the acid for an equivalent amount of a metal, or of a positive compound radical, such at ammonium, NHt.
Pàgina 9 - When an acid contains oxygen, its name is generally formed by adding the terminal ic either to the name of the element with which the oxygen is united, or to an abbreviation of that name; thus sulphur forms, with oxygen, sulphuric acid; nitrogen, nitric acid; and phosphorus, phosphoric acid. But it frequently happens that the same element forms two acids with oxygen ; and when this occurs, the acid containing the...
Pàgina 9 - A more intelligible definition to ordinary readers is that which is adopted by Frankland, in which an acid is described "as a compound containing one or more atoms of hydrogen, which become displaced by a metal, when the latter is presented to the compound in the form of a hydrate.
Pàgina 3 - Hence the law : — Equal volumes of all gases and vapours contain at the same temperature and pressure an equal number of molecules...
Pàgina 35 - The weight of 1 litre of hydrogen being called 1 crith, the volume-weight of other gases, referred to hydrogen as a standard, may be expressed in terms of this unit. For example, the relative volume-weight of chlorine being 35'5, that of oxygen 16, that of nitrogen 14, the actual weights of 1 litre of each of these elementary gases, at 0°C.
Pàgina 21 - These remarkable facts can be explained by a very simple and obvious assumption, viz., that one or more pairs of bonds belonging to an atom of the same element can unite, and, having saturated each other, become, as it were, latent.

Pàgina 34 - The crith is the weight of one litre or cubic decimetre of hydrogen at 0° C. and at a pressure of 760 millimetres of mercury. The following is Dr. Hofmann's description of the value and applications of this unit. " The actual weight of this cube of hydrogen, at the standard temperature and pressure mentioned, is...
