Copper In Nitric Acid
554 words3 Cu + 8 HNO 3 -- 3 Cu (NO 3) 2 + 2 NO + 4 H 2 O The balanced equation seen on the top is what you attain when you place copper metal in concentrated nitric acid. In this process the identifiable characteristics of the metal will be completely changed and a new substance, cupric nitrate, will be formed. Copper forms two series of chemical compounds: cuprous, and cupric. Cuprous compounds are easily oxidized to cupric, in many cases by simple exposure to air; cupric compounds are stable. When nit...

Td Tr Tr Td Erectile Dysfunction
1,318 words... The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernous during sexual stimulation. NO then activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP), producing smooth muscle relaxation in the corpus cavernous and allowing inflow of blood. Sildenafil has no direct relaxant effect on isolated human corpus cavernous, but enhances the effect of nitric oxide (NO) by inhibiting phospho...

Role In The Nitrogen Cycle Nitrogen From The Atmosphere Tree
374 wordsThe nitrogen cycle is a complex biological cycle involving the recycling of usable nitrogen. If this cycle ceased to occur, all forms of life on the planet would die. All life forms, including humans, use nitrogen in compounds called amino acids. These amino acids then act as building blocks for proteins. Nitrogen, in fact, is the most abundant element in the atmosphere. Most organisms are unable to use this nitrogen from the atmosphere and rely on the nitrogen in the soil. The cycle consists of...
