Page 120 - EXPERIMENTS. — A mixture of oxygen and nitrogen, in the proportion of one volume of the former gas to four of the latter, made in a jar over the water-cistern, acts, in reference to combustible bodies, precisely like common air. The contrast between air and its constituents may be shown by taking three jars, one of nitrogen, one of oxygen, and a third of the artificial air, made as above, and introducing into them successively, a lighted taper with a long wick.
Page 35 - ... is proportional to the product of the mass into the square of the velocity. Double your mass, other things being equal, and you double your amount of heat; double your velocity, other things remaining equal, and you quadruple your amount of heat. Here, then, we have common mechanical motion destroyed and heat produced.
Page 111 - Its vapor is greenish-yellow like chlorine. When heated in the air it takes fire and burns with a blue flame tinged with green, evolving white fumes of tellurous oxide.
Page 86 - Preparation. — Hydrogen oxide may be prepared synthetically ; that is by the direct union of its constituent elements. The product of the combustion of hydrogen is always water, as we have seen. (Fig. 6.) And when the two gases are mixed together in the ratio of two volumes of hydrogen to one of oxygen, they may be caused to unite by a flame, by an electric spark, or by finely divided platinum. The heat evolved by their union is very great ; when...
Page 35 - This expresses the fact that water is composed of "2 parts by weight of hydrogen and 16 parts by weight of oxygen, or 1 part of the former to 8 of the latter.
Page 34 - ... negative, an alkalamide results. These three classes of bodies have a structure similar to that of ammonia. They are said therefore to belong to the ammonia type. Amides and amines are often regarded as compounds of the monad radical (H2N/, amidogen. United to R, 86. Naming of Derived Ammonias. — Amides and amines are called primary, secondary, or tertiary, according as one, two, or three of the hydrogenatoms are replaced.

Page 60 - When finely divided copper, antimony, or arsenic, is placed in the gas, it combines with it, with the evolutions of light and heat to form a chloride. Phosphorus at ordinary temperatures, and sodium at more elevated ones, burn in chlorine spontaneously, forming phosphoric and sodium chlorides. Its attraction for hydrogen is specially strong, the two gases exploding violently when mixed together and exposed to sunlight, or on the approach of a flame. In an atmosphere of hydrogen, chlorine gas burns...
Page 209 - Devi lie in 1854. The metal was first prepared from cryolite by H. Rose in 1855. Aluminum, next to oxygen and silicon, is the most abundant element in nature. The mineral corundum is aluminum oxide ; diaspore, chrysoberyl, and spinel, are aluminates ; micas, feldspars, and clays, are aluminum silicates ; and many other minerals contain it as an essential constituent. Its name comes from the Latin alumen, alum, which substance was largely imported into Europe from the east until the fifteenth century.
Page 86 - Hydrogen gases. cubic centimeters of hydrogen are then similarly introduced — all measurements being made when the level of the liquid is the same in both limbs — the open end is closed firmly by the thumb, as shown in the figure — a cushion of air being left between it and the liquid — and a spark passed through the mixed gases by means of the platinum wires. Upon restoring the level of the liquid by adding water, 10 cubic centimeters of gas will be left, which, on examination, will be found...
