Page 20 - ... of alcohol is 0.615; that of mercury is 0.0333; that of thermometer glass is 0.20; that of iron is 0.113; that of copper, 0.0933, etc., these being the numbers of calories of heat required to raise the temperature of 1 gram of each substance, respectively, 1° C. 37-39 CHEMICAL. WARFARE SERVICE b. When a body is cooled by any means, the same amount of heat which was originally put into it in raising its temperature, must again be removed. Thus, the specific heat of a body will determine how much...
Page 28 - ... each which in a gaseous condition at 0° and 760 millimeters will occupy 22.4 liters: b. The weights of the constituent elements making up a GMV of each substance should now be examined. They can be used in the condensed form for representing chemical changes : Oxygen (16)+Hydrogen (2.016)-* Water (18.016) Hydrogen (1.008)+ Chlorine (35.46)-»Hydrogen Chloride (36.468) It is noted at once that the weights in any one column are not identical, but that the weights of any one element are all exact...
Page 16 - boiling point" of a liquid may be denned as that temperature at which its vapor pressure is equal to the atmospheric pressure. And, since the vapor pressure of a liquid rises or falls with rise and fall of temperature, it follows that an increase in the pressure upon a liquid will make it necessary to heat it to a higher temperature to make it boil, and, conversely, a decrease in the pressure upon a liquid will lower its boiling point. 31. Applications of melting and boiling points and vapor pressures....
Page 50 - ... ions are called cations, since they move to the negative electrode, or cathode. The negative ions are the anions and move toward the positive electrode, or anode. /. A positive ion is a free atom or group of atoms which has lost an electron or a number of electrons, such as Na+, H+, NH4+, Zn++.
Page 55 - Again, charcoal, graphite, and the diamond are all carbon but are quite different forms of the same material. When a simple substance shows different forms such as those of oxygen, phosphorus, or carbon, they are called allotropic modifications. SECTION XV COLLOIDS Paragraph Colloidal suspensions 87 Some applications of colloid chemistry 88 87. Colloidal suspensions. — a. The action of suspension of smoke materials in the atmosphere is so similar to that of colloidal suspensions in general that...
Page 28 - SERVICE occupied by 32 grams of oxygen at 0° C. and 760 millimeters pressure ; 32 grams of oxygen are then called the gram-molecular weight of oxygen. The molecular weight of any gas may be measured by weighing any convenient volume of the gas and calculating by proportion the weight of 22.4 liters at 0° and 760 millimeters. The following table contains a few sample substances and gives the weight (in grams) of each which in a gaseous condition at 0° and 760 millimeters will occupy 22.4 liters:...
Page 49 - ... and lower the freezing point by constant amounts. This is uniformly true of nonconducting solutions. Solutions of acids, bases, and salts, however, produce abnormal effects on vapor pressures, boiling points, and freezing points. In many cases the effect is nearly twice normal. The only conclusion that can be drawn from these results is that nearly twice the normal number of solute particles (ions and molecules) are present in such solutions. In other words these solutions behave as if the radicals...
Page 48 - There are four of these properties, all of which have come up previously. 1. Displacement. — A simple radical belonging to an acid, base, or salt in solution can be displaced by another element, and is thereby obtained in the free state. Thus we have already seen (p.
Page 35 - The dissolved substance combines also, in the majority of cases, with part of the water, but the compounds, whatever they are, are physically dissolved in the rest of the water and may be regarded as existent in the solution in the liquid state, just like any unchanged solute. Therefore dissolving is partly a chemical, and partly a physical process. The vapor pressures of solutions are less than that of the pure solvent and it is found that the depression is proportional to the fraction of solute...
