Page 71 - October 1804) contained the first announcement of the fact that oxygen and hydrogen unite to form water in the proportion of one volume of the former to two volumes of the latter (see ATOMIC THEORY).
Page 336 - When heated in the air it takes fire, and burns with a blue flame, forming white fumes of tellurium dioxide.
Page 246 - ... Fluorine does not combine with oxygen. It is the only element of which this statement can be made. Comparison of the Members of the Chlorine Family. — In considering, first, the physical properties of these elements, we notice that all, with the exception of fluorine, form colored gases or vapors. At ordinary temperatures chlorine is a gas, bromine a liquid, and iodine a solid. In regard to their chemical conduct, it may be said that, in general, fluorine exhibits the strongest affinity for...
Page 85 - ... the following general law : that, under equal circumstances of temperature, water takes up, in all cases, the same volume of condensed gas as of gas under ordinary pressure.
Page 263 - If a fine tube is filled one-half with liquid bromine and one-half with the vapour of bromine, and after being hermetically sealed is gradually heated till the temperature is above the critical point, the whole of the bromine becomes quite opaque, and the tube has the aspect of being filled with a dark red and opaque resin.
Page 231 - oxygen of the air, which enters at the bottom of the grate, combines with the carbon of the coal, forming carbon dioxide ; this substance then passing upwards over the red-hot coals, parts with half its oxygen to the redhot carbon. The...
Page 15 - To form some conception of the degree of coarse-grainedness indicated by this conclusion, imagine a rain drop, or a globe of glass as large as a pea, to be magnified up to the size of the earth, each constituent molecule being magnified in the same proportion. The magnified structure would be coarser grained than a heap of small shot, but probably less coarse grained than a heap of cricketballs.
Page 14 - Jointly they establish, with what we cannot but regard as a very high degree of probability, the conclusion that, in any ordinary liquid, transparent solid, or seemingly opaque solid, the mean distance between the centres of contiguous molecules is less than the 1/5,000,000, and greater than the 1/1,000,000,000 of a centimetre.
Page 90 - Hence, by analogy, it may be inferred that the molecules of these several salts, as they exist in solution, possess densities which are to one another as the squares of the times of equal diffusion. Thus, the solution-densities of sulphate, nitrate, and hydrate of potash, are to one another as the numbers 4, 2, and 1.
