WebCopper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. WebApr 1, 2024 · Sorted by: 3. By burying the copper wire with plenty of sulfur and then heating the mix, the wire becomes completely submerged in liquid sulfur. The liquid sulfur then gets to react with the copper, and any oxygen that could possibly oxidize the copper would have to diffuse into the liquid sulfur before reaching the copper.
Webformula mass corresponds to the molecular formula H 2 O 2. Example 1: To find the empirical formula of a sulfide of copper, 1.956 g of copper wire is heated with a large excess of elemental sulfur. An excess of sulfur ensures that all the copper reacts. Unreacted sulfur burns off to leave behind copper sulfide weighing 2.477 g.

WebJun 4, 2024 · The half-reactions are: Cu --> Cu 2+ + 2 e- , meaning that copper loses two electrons, and 2 e- + 4 HNO 3---> 2 NO 3 1-+ 2 H 2 O, which shows that two electrons have been transferred to the products. The speed of this reaction depends on the surface area of the copper; copper wire will react more quickly than copper bars, for example. stephen smyth gojoWebConcentrated nitric acid reacts with copper and produce copper nitrate ( Cu(NO 3) 2), nitrogen dioxide (NO 2) gas and water as products. In this reaction, copper is oxidized to its +2 oxidation state while nitric acid is reduced to nitrogen dioxide.
