Metallic hydrides and carbides may in a sense be regarded as or^uiometallic compounds: that is, they may be considered as first members of a series in which the hydrogen or carbon atoms may be replaced by methyl, ethyl, phenyl or other groups to produce what is more generally considered to be an organo- metallic compound. Ifhallium hydride has never been isolated, but its existence can be demonstrated speotrographically when an arc is caused to pass between thallium electrodes in an atmosphere of hydrogen.®® From the spectroscopic data the entropy of the gaseous diatomic hydride has been craoputed, and the thallium-hydrogen bond distance calculated to be 1.870 A. Thallium in the molten state does not dissolve any appreciable 114 amount of carbon, nor does it form a carbide. There is no record in the literature of a thallim carbonyl, or of a thallium acetylide. An amoniacal thallous salt solution does not yield a precipitate with acetylene, as do copper and silver. Thallium in this and in many other respects resembles the alkali metals. As a soft, low-melting, malleable metal, thalliiim ia its elementary form probably most resembles lead. In spite of its plae© in the third group of the periodic table, its ocaamon valence is one, and in many of its properties it resembles the alkali aetals, especially potassium. A long series of thalloua and potassiiia salts crystallizes in isomorphous systems. fhallous hydroxide and carbonate are strong bases and readily soluble ia water, in both of which respects they resemble the alkali metals. In the solubility of its fluoride, and insolu­

M. Brooks, Statistical Reporting Service, U.S. Dept. of Agriculture 1977 I FOREWORD The Statistical Reporting Service, as with any organization, needs to know its past to understand the present and appraise the future. Accordingly, our technical procedures are peri- ^odically set forth in ''Scope and Methods of the Statistical Reporting Service," and the agency's early development and program expansion were presented in "The Story of Agricultural Estimates." However, most important are the people who de- veloped this complex and efficient statistical service for agriculture and those who maintain and expand it today. Dr. Harry C. Trelogan, SRS Administrator, 1961-1975, arranged for Emerson M. Brooks to prepare this informal account of some of the people who steered SRS's course from 1933 to 1961. The series of biographical sketches selected by the author are representative of the people who helped develop the per- sonality of SRS and provide the talent to meet challenges for accurate and timely agricultural information. This narrative touching the critical issues of that period and the way they'^ were resolved adds to our understanding of the agency and helps maintain the esprit de corps that has strengthened our work since it started in 1862. Our history provides us some valuable lessons, for "those who cannot remember the past are condemned to repeat it." W.

  • Chemical Resistance of Plastics
    (c) Bürkle GmbH 2010 Important Important information The tables “Chemical resistance of plastics”, “Plastics and their properties” and “Viscosity of liquids" as well as the information about chemical resistance given in the particular product descriptions have been drawn up based on information provided by various raw material manufacturers. These values are based solely on laboratory tests with raw materials. Plastic components produced from these raw materials are frequently subject to influences that cannot be recognized in laboratory tests (temperature, pressure, material stress, effects of chemicals, construction features, etc.). For this reason the values given are only to be regarded as being guidelines. In critical cases it is essential that a test is carried out first. No legal claims can be derived from this information; nor do we accept any liability for it.

In February 1987, the Bureau cf Indian Affairs (BIA) recommended that the school be closed, and that students be transferred to Sherman Indian Schoo] in Riverside, California. Congressional hearings in February and July 1987 received testimony on this proposal and on several plans for disposition of the federal land involved, about ,100 acres of valuable real estate within the city of Phoenix. A B1A spokesman cited declining enrollment and Lurther declines expected after the opening of two new reservation secondary schools as justification for the closure, and provided data on studer:, program, and school characteristics at Phoenix and Sherman schools. Representatives of Arizona tribes and the Inter-Tribal Council of Arizona (ITCA) testified that there are only five reservation high schools in Arizona, and that Phoenix Indian High School provides needed educational resources for Arizona's Indian students, particularly special needs students.

Exposure standards for soluble compounds can be up to 500 times lower than the exposure standards for less soluble compounds for the same metal. However, there is often confusion among chemists, industrial hygienists, and laboratories over what is meant by “soluble” when the metal species, extraction fluid, or solubility conditions are not specified in the exposure standard nor in the supporting exposure standard documentation [Fairfax and Blotzer 1994]. In addition, the metals and metal compounds may interact chemically or physically with the sampling media or with each other [Ashley 2001]. Such complications can affect the stability and speciation of the metals and their compounds, and must be addressed in order to obtain meaningful results.

Salient Features of Mercury Mercury is a heavy and silvery-white metal. Mercury usually available inin liquidliquid state; inin normal condition, itit isis only thethe fewfew metallic element that remains in liquid state at room temperature. Mercury is the poor conductor of heat, but it is a good conductor of the electricity.. The freezing point of mercury is −38.830C and the boiling point is 356.730C. Mercury poisoning caused because of thethe ingestingingesting any formform of mercury.. ItIt isis also caused by inhalation of mercury vapor.. https://www.tutorialspoint.com/chemistry_part2/chemistry_mercury.htm 1/3 1/24/2021 Chemistry - Mercury - Tutorialspoint Mercury dissolves many metals including gold and silver to form amalgams. Occurrence of Mercury Mercury is one of the rarest element in the earth’s crust. The richest mercury ores carry about 2.5 percent mercury (in terms of mass). Mercury isis foundfound either as a native (natural) element) or inin corderoite, cinnabar,, livingstonite,livingstonite, etc.etc. minerals.minerals.
