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.

Paperback. Zustand: New. Print on Demand. This book focuses on the early development of chemistry from the time of Antoine Lavoisier to the introduction of the periodic table by Dmitri Mendeleev. Lavoisier, the father of modern chemistry, developed a new system of chemical nomenclature, identified oxygen, and helped establish the law of conservation of mass. The author traces the development of chemistry through the work of scientists such as Joseph Priestley, Henry Cavendish, Humphry Davy, JÃ ns Jakob Berzelius, and others. The book examines the development of atomic theory and the periodic table, as well as the role of chemistry in the Industrial Revolution. The insights in this book form the foundation of our understanding of chemical reactions and laid the groundwork for modern chemistry, making it an essential read for anyone interested in the history and foundations of the field. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
