Copper has 2 possible valence configurations: Cu+1 or Cu+2. In either case, the products would be Copper oxide but their chemical characteristics, and their formulas, would be different, due to the difference in valence.
For Cu+1, the product would be a red powder, of the formula, Cu2O.
For Cu+2, the product would be a black powder, of the formula, CuO
Cu(C2H3O2)2
4Fe + 3O2 = 2Fe2O3 in the presence of water.
looks like a single displacement reaction. Cu + AgSO4 Thank you very much!
CuCl2
N,(nitrogen), O (oxygen) and Cu (copper) are all elements. Nitrogen is only found as the gas N2. Oxygen has several molecular forms, including the best known the gas O2. Copper is found as metal. So it is True.
49.7g O2
Cu (copper) reacts with CO2 (carbon dioxide), H2O (water), and O2 (oxygen) to form a product. The specific product formed depends on the reaction conditions and stoichiometry. Without further information, it is not possible to determine the exact reaction and product formed.
no reaction because Cu is below Zn at electrochemical series ,so Cu can't take Zn away from its salts
CuCl2 is the product.
n+o2=no2
Hydrogen peroxide.
The product is nitrogen dioxide.
The final answer would be 2Cu O2---> 2CuO
The chemical reactions are:4 Cu(I) + O2 = 2 Cu2O2 Cu(II) + O2 = 2 CuO
It can be either depending on the reaction. For example. here it is a product. 2Cu + H2O + CO2 + O2 --> Cu(OH)2 + CuCO3 it is a product. While in this reaction CuCO3 + 2HCl --> CuCl2 + CO2 + H2O it is a reactant.
The product is water:2 H2 + O2 = 2 H2O
Cu+
Cu(I), cuprous, Cu+.
