Anhydrous Cu(NO 3) 2 is one of the few anhydrous transition metal nitrates. [9] It cannot be prepared by reactions containing or producing water. Instead, anhydrous Cu(NO 3) 2 forms when copper metal is treated with dinitrogen tetroxide: [6] Cu + 2 N 2 O 4 → Cu(NO 3) 2 + 2 NO
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).
Cu 2 C 2: copper(I) acetylide: 1117–94–8 Cu 2 Fe(CN) 6: copper(II) ferrocyanide: 13601–13–3 Cu 2 O: copper(I) oxide: 1317–39–1 Cu 2 P 2 O 7: copper(II) pyrophosphate: 10102–90–6 Cu 2 S: copper(I) sulfide: 22205–45–4 Cu 2 Se: copper(I) selenide: 20405–64–5 Cu 2 Te: copper(I) telluride: 12019–52–2 Cu 3 (AsO 4) 2 ...
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
The nitrate salt of the acetonitrile complex, i.e., [Cu(MeCN) 4]NO 3, is generated by the reaction of silver nitrate with a suspension of copper metal in acetonitrile. [2] Cu + AgNO 3 + 4 CH 3 CN → [Cu(CH 3 CN) 4]NO 3 + Ag. Tertiary phosphine complexes of the type [Cu(P(C 6 H 5) 3) 3]NO 3 are prepared by the reduction of copper(II) nitrate by ...
The tetrahydrate consists of discrete, octahedral [(H 2 O) 4 Co(NO 3) 2] molecules. The hexahydrate is better described as hexaaquacobalt(II) nitrate, [Co(OH 2) 6][NO 3] 2, as it consists of discrete [Co(OH 2) 6] 2+ and [NO 3] − ions. [5] Above 55 °C, the hexahydrate converts to the trihydrate and at higher temperatures to the monohydrate. [2]
2 NaOH + CuO + H 2 O → Na 2 [Cu(OH) 4] It can also be reduced to copper metal using hydrogen, carbon monoxide, and carbon: CuO + H 2 → Cu + H 2 O CuO + CO → Cu + CO 2 2 CuO + C → 2Cu + CO 2. When cupric oxide is substituted for iron oxide in thermite the resulting mixture is a low explosive, not an incendiary.
The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound.The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.
