Hydrogen Cyanide Decontamination. Because of its physical properties, hydrogen cyanide will not remain for long in its liquid state. Decontamination should not, therefore, be necessary. The same is true of cyanogen chloride and cyanogen bromide.

Is fluorine an element 1 Since fluorine had never been previously isolated, it remained for H. Moissan to prove that the gas he found to be liberated at the positive pole is really fluorine. Many of its physical and chemical properties, as will be shown later, agree with those suggested by the analogy of the fluorides with the chlorides, bromide, and iodides. It was found impossible to account for its properties by assuming it to be some other gas mixed with nitric acid, chlorine, or ozone or that it is a hydrogen fluoride richer in fluorine than the normal hydrogen fluoride. 

Physical Condition of the Metal.—The more finely divided the metal the greater is its power of occluding hydrogen. This probably explains many of the apparently anomalous results detailed in the literature on the subject. Thus, for example, cobalt reduced from the bromide does not possess the property of occluding hydrogen to any important extent.6 The metal obtained, on the other hand, by reduction from its oxides contains varying amounts of the gas. Reduced at...
