Nitrogen is highly compressible, inert and miscible with water, making it suitable for a wide range of industrial applications. For example, pharmaceutical companies use high purity nitrogen to synthesize and preserve compounds used in the production of drugs. Food processing companies use nitrogen in ...
BICYCLIC COMPOUNDS WITH TWO COMMON NITROGEN ATOMS; PHARMACEUTICAL COMPOSITIONCompounds of the formula I wherein R1 is hydrogen, alkanoyl or aroyl; R2 is hydrogen or alkyl; R3 is hydrogen or aryl; R4 and R5 each are hydrogen or R4 and R5 taken together are oxo; and Y is -CH2-, -CH2...

The most common group of minerals are in the (a) ___ group. This is not surprising since the two elements most common in the crust are (b) ___ and (c) ___. Minerals in the Earth: Minerals are the inorganic chemical ...
the next three elements that occur in greatest abundance in the human body are nitrogen, calcium and phosphorous. together, these elements make up about six percent of the total weight of the human body. nitrogen is found in the proteins, while calcium and phosphorous have their greatest concent...
A series of model compounds covering a wide range of boiling points (108掳 to 323掳C) and polarity was used. Based upon recovery efficiency alone, nitrogen blowdown was significantly superior to the other macro techniques; however, its extreme slowness gave K-D the highest Figure of Merit. ...
The earth is composed of mineral elements, either alone or in a myriad of combinations called compounds. A mineral is composed of a single element or compound. By definition, a mineral is a naturally occurring inorganic substance with a definite chemical composition and ordered atomic structure. ...

Structure of Nucleotide and Nucleoside A nucleoside by definition has two distinct parts: a cyclic, nitrogen-rich amine called a nitrogenous base, and a five-carbon sugar molecule. The sugar molecule is either ribose or deoxyribose. When a phosphate group becomes hydrogen-bonded to a nucleoside, ...
Combining cations and anions to form binaryinorganic compoundsis simple. The same prefixes are applied to indicate the quantities of cation or anion atoms. Examples include the name of water, H2O, which is dihydrogen monoxide, and the name of NO, which is nitrogen dioxide. ...
