| nitrohydrochloric acid |
Aqua regia (Latin for "royal water") is a highly corrosive, fuming yellow liquid, formed by a fresh mixture of concentrated nitric acid (otherwise known as aqua fortis) and concentrated hydrochloric acid, usually in the ratio of one to three. It is one of the few reagents able to dissolve gold and platinum. It was so named because it can dissolve the so-called royal, or noble metals, although tantalum and a few other extremely passive metals are able to withstand it. ...

| nitrogen narcosis |
Nitrogen narcosis or inert gas narcosis is a reversible alteration in consciousness producing a state similar to alcohol intoxication in SCUBA divers at depths beyond 30m. Jacques Cousteau famously described it as the "rapture of the deep". Its precise mechanism is not well understood, but it appears to be a direct effect of high nitrogen pressure on nerve transmission. ...

| nitrogenase |
Nitrogenase (EC 1.18.6.1)is the enzyme used by organisms to fix atmospheric nitrogen gas (N2). Dinitrogen is relatively inert due to its triple bond. The enzyme therefore requires uses a lot of chemical energy in the form of ATP and reducing agents, such as NADH. The product of the reaction is ammonia, which is normally incorporated into glutamate to form glutamine. The enzyme is composed of a dimer of "MoFe" associated with a dimers of "Fe" each. ...

| nitrous oxide |
Nitrous oxide, also known as dinitrogen oxide or dinitrogen monoxide, is a chemical compound with chemical formula N2O. Under room conditions it is a colourless non-flammable gas, with a pleasant slightly sweet odor. It is commonly known as laughing gas due to the exhilarating effects of inhaling it, and because it can cause spontaneous laughter in some users. It is used in surgery and dentistry for its anaesthetic and analgesic effects. ...
