For the year ended June 30, 1990, about 39% of the total primary nutrient used in the United States was apphed in mixtures, whereas the remaining 61% was apphed by direct apphcation. Breakdown by plant nutrient is shown in Table 11. High usage of anhydrous ammonia and nitrogen solutions (Fig. 

In a vacuum, uncoated molybdenum metal has an unlimited life at high temperatures. This is also tme under the vacuum-like conditions of outer space. Pure hydrogen, argon, and hehum atmospheres are completely inert to molybdenum at all temperatures, whereas water vapor, sulfur dioxide, and nitrous and nitric oxides have an oxidizing action at elevated temperatures. Molybdenum is relatively inert to carbon dioxide, ammonia, and nitrogen atmospheres up to about 1100°C a superficial nitride film may be formed at higher temperatures in the latter two gases. Hydrocarbons and carbon monoxide may carburize molybdenum at temperatures above 1100°C. 

Air emissions at point of discharge should be monitored continuously for fluorides and particulates and aimually for ammonia and nitrogen oxides. Monitoring data should be analyzed and reviewed at regular intervals and compared with the operating standards so that any necessary corrective actions can be taken. Records of monitoring results should be kept in an acceptable format. The results should be reported to the responsible authorities and relevant parties, as required. 

Nitrogen can react with steam to form ammonia and nitrogen oxide gases. A 20.0-L sample of nitrogen at 173°C and 772 mm Hg is made to react with an excess of steam. The products are collected at room temperature (25°C) into an evacuated flask with a volume of 15.0 L. 

Calculate the equilibrium partial pressure of hydrogen if the equilibrium partial pressures of ammonia and nitrogen are 0.015 atm and 1.2 atm, respectively. 

Various secondary sources of safety data are now listing this as an explosive. I can find no primaiy source for this classification, which seems very improbable. Simple minded use of many computational hazard prediction procedures would show thermodynamically that this compound, like most lower amines, could hypothetically convert to alkane, ammonia and nitrogen with sufficient energy (about 3 kJ/g) to count as an explosion hazard. This reaction is not known to happen. (Simple minded thermodynamicists would rate this book, or computer, and its reader as a severe hazard in an air environment.) Like other bases, iminobispropylamine certainly sensitises many nitro-explosives to detonation. It is used experimentally to study the effect, which may have found technical exploitation and, garbled, could have led to description of the amine as itself an explosive. 

The product decomposes on sublimation forming mercury(ll) chloride, ammonia, and nitrogen. However, in the presence of ammonium chloride, the same reaction with ammonia with HgCb in aqueous solution yields fusible white precipitate, (NH3)2HgCl2. Similar product also is obtained by reaction of gaseous ammonia with solid mercury(II) chloride. However, the solid mer-cury(II) chloride is more stable than the above infusible product and can be melted without decomposition. 

When heated, mercuric amido-chloride decomposes with loss of ammonia and nitrogen, leaving a residue of mercuric cliloride. It does not melt during decomposition, and if boiled with aqueous sodium hydroxide all the nitrogen is eliminated as ammonia. Water hydrolyses it, giving ammonium chloride and oxydimereuriamido-chloride thus ... 

The following reactions were included in the kinetic model NH3 adsorption (R3 in Table V), NH3 desorption (R4 in Table IV), NH3 oxidation (R5 in Table IV) and standard SCR (R6 in Table V). Mass balances for adsorbed ammonia and nitrogen now include the standard SCR reaction. Moreover, the mass balance of gaseous NO was introduced, too...

NHS + 3 NOa + NO + Na + 5 HaO, but there were also found present an all amts of NaO and HNO. in the gaseous products of decompn. Some of the above products of decompn (ammonia and nitrogen oxides) interacted with the evoln of heat. This heat might raise the temp of the gases above the molten AN to such an extent that they could explode and cause the explosn of the molten AN in the tube. In order to avoid the danger of expln... 

In the first stage of the reaction an alkoxyl anion and the nitrohydrazine cation are formed which afterwards react together to give the corresponding alcohol and nitrohydrazine. Nitrohydrazine reacts with excess hydrazine to produce tetrazene, nitrous acid and di-imid. Then the tetrazene decomposes to form ammonia and nitrogen from di-imid on the other hand tetrazene, hydrazine and nitrogen are formed. Hydrazoic acid and ammonia are then formed as decomposition products of tetrazene.

There were disturbances due to the liquefaction of the gas. P. Isambert found that the coeff. of compressibility of aq. soln. of ammonia is less than that of water alone and the more cone, the soln., the smaller the compressibility. For a litre of liquid at 21-5° containing 330 litres of dissolved gas, the coeff. was 0-0000376, and at 20-4° with 140 litres of dissolved gas, 0-0000387. Observations were also made by G. M. Maverick, and E. L. Nichols and A. W. Wheeler. 0. Maass and D. M. Morrison studied the effect of molecular attraction on the total press, of ammonia and E. Lurie and L. J. Gillespie, the equilibrium press, of mixtures of ammonia and nitrogen. F. Schuster calculated 4512 atm. for the internal pressure of the liquid and J. H. Hildebrand, 3900 atm.
