Page 481 - Plants absorb carbonic acid from the air, under certain circumstances, and emit oxygen in return. When a healthy plant, the roots of which are supplied with proper nourishment, is exposed to the direct solar beams in a given quantity of atmospheric air, the carbonic acid, after a certain interval, is removed, and an equal volume of oxygen is substituted for it. If a fresh portion of carbonic acid is supplied, the same result will ensue. But...
Page 51 - Consequently, the pressure or whole weight upon any one particle arises solely from those of its own kind. " 2. The force of steam from all liquids is the same at equal distances above or below the several temperatures at which they boil in the open air: and that force is the same under any pressure of another elastic fluid as it is in vacua.

Page 424 - Thomson procured a binacetate by mixing acetic acid and carbonate of potassa in the proportion of two equivalents of the former to one of the latter.
Page 194 - ... incapable of uniting, when presented to each other in their gaseous form. Its formation is owing to the decomposition of ammonia (a compound of hydrogen and nitrogen) by chlorine. The hydrogen of the ammonia unites with chlorine, and forms muriatic acid ; while the nitrogen of the ammonia, being presented in its nascent state to chlorine, dissolved in the solution, enters into combination with it. The chloride of nitrogen...
Page 338 - It may be prepared by decomposing the carbonate of cobalt by heat, in a vessel from which the atmospheric air is excluded. It is easily known by its giving a blue tint to borax when melted with it, and is employed in the arts, in the form of smalt, for communicating a similar color to glass, to earthen ware, and to porcelain.
Page 254 - ... of sulphur over fragments of charcoal heated to redness in a tube of porcelain. The compound, as it is formed, should be conducted by means of a glass tube into cold water, at the bottom of which it is collected. To free it from moisture and adhering sulphur, it should be distilled at a low temperature in contact with chloride of calcium.
Page 269 - Order 2. Metals which do not decompose water at any temperature, and the oxides of which are not reduced to the metallic state by the sole action of heat.
Page 130 - When the action of heat, the electric spark and spongy platinum no longer cause an explosion, a silent and gradual combination between the gases may still be occasioned by them. Oxygen and hydrogen gases unite slowly with one another when exposed to a temperature above the boiling point of mercury, and below that at which glass begins to appear luminous in the dark. An explosive mixture, diluted with air to too great a degree to explode by electricity, is made to unite silently by a succession of...
