Publisher's Synopsis
Excerpt from The Principles of Chemistry, Vol. 2
It is composed of two volumes of nitrogen and one volume of oxygen. By decomposing ammonia by the action of an electric spark it is easy to prove that it contains one volume of nitrogen to three volumes of hydrogen. So. Similarly, it is found, whenever a compound is decom posed and the volumes of the gases proceeding from it are measured, that the volumes of the gases or vapours entering into combination are in a very simple proportion to one another. With water, nitrous oxide, &c., this may be proved by direct observation but in the majority of cases, and especially with substances which, although volatile - that is, capable of passing into a gaseous (or vaporous) state-are liquid at the ordinary temperature, such a direct method of observation presents many difficulties. But, then, if the densities of the vapours and gases be known, the same simplicity in their ratio is shown by calculation. The volume of a substance is proportional to its weight, and inversely proportional to its density, and therefore by dividing the amount by weight of each substance entering into the composition of a compound by its density in the gaseous or vaporous state we shall obtain factors which will be in the same proportion as the volumes of the substances entering into the composition of the compound.' So, for example. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
