of hydrogens. … Ignore the number of oxygens. … Subtract the number of nitrogens from the number of hydrogens. John McMurry, Organic Chemistry 8th ed....

plants. The chief and most valuable among these substances are compounds of nitrogen, and the cheap production of these is, therefore, the key for the solution...

climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Θάλαττα! θάλαττα! Thalatta! Thalatta! The sea, the sea! Anonymous...

consequences. Nitrogen comes from a vast array of sources: farm fertilizer, car exhaust, factory and power plant emissions. Scientists expect nitrogen deposition...

thought to have been first to use liquid nitrogen, in 195017. He recognized that the properties of liquid nitrogen were very similar to those of liquid air...

fixation of atmospheric nitrogen for industrial and agricultural purposes, and thus greatly increase the supply of nitrogen compounds needed in the industries...

transformable, and its proximate origin is of no importance whatsoever. Nitrogen is nitrogen, it passes miraculously from the air into plants, from these into...

Amines are organic compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are derivatives of ammonia, wherein one or...

objective long sought by chemists—that of fixing nitrogen from air. Atmospheric nitrogen, or nitrogen gas, is relatively inert and does not easily react...

occurring chemical compounds (natural products) that contain mostly basic nitrogen atoms. This group also includes some related compounds with neutral and...

approximately 80 million tons of nitrogen nutrients are utilized each year. If you tried to produce this nitrogen organically, you would require an additional...

rocks atoms escaped for eventual incorporation in living things: carbon, nitrogen, oxygen, phosphorus and sulphur for all living tissue; calcium for bones...

are vital because they provide fixed nitrogen for agricultural soils (the recent substitution of synthetic nitrogen fertilizers certainly being a temporary...

consumptive and reduce our reliance on nitrogen. It's like a carbon footprint. But you can reduce your nitrogen footprint. I do it by not eating much meat...

formed hydrocyanic acid by the action of the electric spark on a mixture of nitrogen and acetylene. [O]f the numerous syntheses of Berthelot, or the building...

plants. The chief and most valuable among these substances are compounds of nitrogen, and the cheap production of these is, therefore, the key for the solution...

like this in a nitrogen filled environment, but you earthlings breath oxygen. Ben Tennyson: Surprise! Earth's atmosphere has nitrogen in it too pal! Pax:...

acting with solution of ammonia on the iodine to be treated, thus forming nitrogen iodide, or diodamine, as he considered it, decomposing the violently explosive...

in part because they are strongly stabilized by delocalization of the nitrogen lone pair (...) As a consequence, their nucleophilic addition – eliminations...

operation. The team from a Houston-based company, Boots & Coots, using liquid nitrogen and water, put out a relatively small fire on its second attempt this morning...
