The chemical name of compounds composed of only two elements usually ends with the suffix ide. The chemical name for water, for example, which is composed of two atoms of hydrogen and one of oxygen, and whose chemical formula is H20, is, therefore, hydrogen oxide. The chemical name for common table salt, composed of one atom of sodium and one of chlorine, and has the formula is NaCI, is sodium chloride. Pyrite, an iron ore composed of one atom of iron (ferrum in Latin) and one of sulfur, has the formula FeS, and its chemical name is ferrous sulfide. 

Mirex is a white, odorless, free-flowing, crystalline, nonflammable, polycyclic compound composed entirely of carbon and chlorine. The empirical formula is C10C112, and the molecular weight 545.54 (Hyde 1972 Waters et al. 1977 Bell et al. 1978 NAS 1978 Menzie 1978 Kaiser 1978). In the United States, the common chemical name is dodecachlorooctahydro-l,3,4-metheno-2H-cyclobuta[c,systematic name is dodecachloropentacyclo 5.3.0.02-6.03 9.04 8decane. Mirex was first prepared in 1946, patented in 1955 by Allied Chemical Company, and introduced...

The chemical name for rust is iron oxide. Normally, iron rusts more quickly if it is wet. However, iron can be kept underwater without rusting if the water is first boiled, to drive off its oxygen, and the container sealed with oil to prevent the oxygen from re-entering. 

The conventional way to remove hair from cowhides is to use harsh chemicals, namely slaked lime and sodittm sttlfide. These chemicals completely dissolve the hair and open up the fiber stmctrrre. Errzyme-assisted tmhairing, with or without recovery of the hair, is closely related to the conventional process. However, just by adding an ertzyme, it is possible to reduce the reqrrirements for soditrm strlfide and lime. This process gives a very clean pelt, a high area yield and resrrlts in fewer chemicals in the waste water.

Tables 1 and 2 show the chemical name, molecular formula, water solubility, and vapor pressure of representative carbamate and urea pesticides.

Creatine monohydrate, the most popular form of off-the-shelf creatine supplementation, is an odorless, white, water-soluble powder. Its chemical name is N-(ammoimmomethyl)-N-methylglycine monohydrate. 

The first water-soluble vitamin discovered was called vitamin B to distinguish it from vitamin A. Later other B vitamins were discovered and given names such as vitamin B2, B2, etc. Now the specific chemical names are used. In distinction to the fat-soluble vitamins, the water-soluble vitamins are not absorbed with fats and they are not stored in appreciable quantities in the body (with the possible exception of B12 and thiamin). Excesses of these vitamins are excreted rapidly in urine, requiring a constant dietary supply. 

In the interest of conserving space in this handbook, a compact tabular presentation format has been adopted. Table 5.1.5.1 lists the chemical name, and its freon number (if applicable), molecular formula, molar weight and melting and boiling points. These data are available for virtually all substances in this group. Also shown in this table is the availability, expressed as a tick mark, of data on vapor pressure, solubility in water, octanol-water partition coefficient (Kqw) and the second order reaction rate constant with hydroxyl radicals. This rate constant is the critical determinant of persistence in the atmosphere. Tables 5.1.5.2 to Table 5.1.5.5 list the compounds and give the available property data with citations.

Stanley Miller was impressed by the ease of synthesis of adenine from simple molecules, but the cell eschews simple synthesis. In fact, if we dissolved in water (using the formal chemical names) ribose-5-phosphate, glutamine, aspartic acid, glycine, N10-formyl-THF, carbon dioxide, and energy packets of ATP and GTP—all the small molecules that are used by the cell to build AMP—and let them sit for a long time (say, a thousand or a million years) we would not get any AMP.8 If Stanley Miller mixed these chemicals hoping for another rock of the faith, he would be quite disappointed. 

The operating principle of such devices relies on materials whose volume changes abruptly, i.e., that display a volume phase transition (VPT), when an appropriate stimulus is applied. Thermosensitive poly(N-isopropylacrylamide) (PNIPA) hydrogel, where the cross-links are chemical, namely peptide bonds, is widely used for this purpose since its VPT in pure water is close to 34°C.1 3...
