Page 217 - A careful study of the conduct of gases has led to the conclusion that equal volumes of all gases under the same conditions of temperature and pressure contain the same number of molecules.
Page 93 - All these facts taken together prove that the composition of water is what it has been stated to be. Now, using the accepted combining weights of hydrogen and oxygen, viz., 1 and 16, — the simplest formula which expresses the composition of water is H,O.
Page 229 - Avogadro's principle or hypothesis, which states that equal volumes of all gases under the same conditions of temperature and pressure contain the same number of molecules, was the extension of Dalton's Atomic Theory necessary to put the theoretical interpretation of chemistry on a solid foundation.
Page 345 - ... the quantity of heat required to raise the temperature of the same weight of water one degree is called the specific heat of the substance.
Page 249 - The needles belong to the monoclinic system of crystals, and the octahedrons to the rhombic system. Crystallography. — Notwithstanding the infinite number of forms assumed by solids in passing from the liquid to the solid state and when deposited from solutions, it has been shown that all can be referred to a very few systems. Usually six systems are adopted. These are : 1. THE REGULAR SYSTEM. All the crystals belonging to this system can be referred to three axes of equal length, and at right...
Page 31 - Very frequently the first letter of the name of the element is used as the symbol. If the names of two or more elements begin with the same letter, this letter is used, but some other letter of the name is added.

Page 127 - Enclose 60 to 80 cc. air in the tube over water. Arrange the tube so that the level of the water inside and outside is the same. Note the temperature of the air and the height of the barometer. Reduce the observed volume to standard conditions. Now introduce a piece of phosphorus, as in Experiment 24, and allow it to stand for twenty-four hours.
Page 333 - Heat a small piece of zinc on charcoal in the oxidizing flame of the blowpipe. The white fumes of zinc oxide (philosopher's wool) will be seen, and the charcoal will be covered with a film which is yellow while hot, but becomes white on cooling.
Page 125 - It will be noticed that the terminal syllable of the name of the salt differs according to the name of the acid. If the name of the acid ends in ic, the name of the salt derived from it ends in ate. If the name of the acid ends in ous, the name of the salt ends in ite.
