  2. Nickel(II) nitrate - Wikipedia

    en.wikipedia.org/wiki/Nickel(II)_nitrate

    Nickel nitrate is the inorganic compound Ni(NO 3) 2 or any hydrate thereof. In the hexahydrate, the nitrate anions are not bonded to nickel. Other hydrates have also been reported: Ni(NO 3) 2. 9H 2 O, Ni(NO 3) 2. 4H 2 O, and Ni(NO 3) 2. 2H 2 O. [3] It is prepared by the reaction of nickel oxide with nitric acid: NiO + 2 HNO 3 + 5 H 2 O → Ni ...

    This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.

  4. Nickel(II) nitrite - Wikipedia

    en.wikipedia.org/wiki/Nickel(II)_nitrite

    Nickel(II) nitrite is an inorganic compound with the chemical formula Ni(NO 2) 2. [1] Anhydrous nickel nitrite was first discovered in 1961 by Cyril Clifford Addison, who allowed gaseous nickel tetracarbonyl to react with dinitrogen tetroxide , yielding a green smoke.

    The nickel holding is done by a "nickel binding hook" which as the amino acid pattern H 2 N-His-Cys-X-X-Pro-Cys-Gly-X-Tyr-rest of protein, where the bold bits are ligands for the nickel atom. [ 57 ] Nickel transporter proteins exist to move nickel atoms in the cell. in E. coli these are termed Nik A, Nik B, Nik C, Nik D, Nik E.

  6. Nickel - Wikipedia

    The US nickel coin contains 0.04 ounces (1.1 g) of nickel, which at the April 2007 price was worth 6.5 cents, along with 3.75 grams of copper worth about 3 cents, with a total metal value of more than 9 cents. Since the face value of a nickel is 5 cents, this made it an attractive target for melting by people wanting to sell the metals at a profit.

  7. Lateritic nickel ore deposits - Wikipedia

    en.wikipedia.org/wiki/Lateritic_nickel_ore_deposits

    The ore is stacked on impermeable plastic membranes and acid is percolated over the heap, generally for 3 to 4 months, at which stage 60% to 70% of the nickel-cobalt content is liberated into acid solution, which is then neutralised with limestone and a nickel-cobalt hydroxide intermediate product is generated, generally then sent to a smelter ...
