NOT +2
Added:In Cu2O the ion charge is Cu1+, (cuprous oxide, Cu(I) oxide, oxidation state +1) color brownish red (or yellow, depending on how fine the particles are)In CuO the ion charge is Cu2+, (cuprous oxide, Cu(II) oxide, oxidation state +2) color black
Cu2O is an ionic compound, and the bonds between the cuprous ions and the oxygen ion are ionic. Just about every time you have a metal bonded with a nonmetal (especially if the nonmetal is oxygen, chlorine, or fluorine), it is going to be an ionic compound with ionic bonds.
Cu2O, or cupric oxide is an ionic compound. It is ionic because Cu is a metal, and oxygen is a non metal.
I think you are asking for a common valence value...yes? Copper [Cu+] is generally associated wth a positive valence.
Copper(I) oxide
Oxygen is nearly always a -2 charge.
It has valency 1.
copper (I) oxide
It is 2-.
The valency of copper in Cu2O is'1'
cuprous oxide :)
When the product is with oxygen it will be copper oxide CuO. If it is with nitrogen it is copper nitrate.
R-CHO + 2Cu2+ + 4OH- ----------> R-COOH + Cu2O + 2H2O where R is the group attached to the aldehyde (CHO)
Do you mean carbon dioxide(carbon IV oxide - CO2) or carbon monoxide CO
Cu2O. Cuprous is Cu+, cupric is Cu2+. Those are old-school names. Copper(I) oxide is a better name.
cuprous oxide :)
Copper I oxide is Cu2O
The chemical formula is Cu2O
Copper (II) oxide or cupric oxide: CuO.Copper (I) oxide or cuprous oxide: Cu2O.
Copper (II) oxide or cupric oxide: CuO.Copper (I) oxide or cuprous oxide: Cu2O.
Cuprous oxide, or copper (I) oxide, Cu2O, is a red powder.Cupric oxide, or copper (II) oxide, CuO, is a black powder.
Cu2O, where the 2 should be a subscript, is copper(I) oxide or cuprous oxide to give it its old name. It is found naturally as the ore cuprite. It is a red-brown powder, whereas the copper(II) oxide we see when copper is heated is black.
4Na(OH)3+2CUSO4-->CU2O+H2O+2NA2SO4
Cuprous oxide or Copper(I) oxide is found as the reddish mineral cuprite.
When the product is with oxygen it will be copper oxide CuO. If it is with nitrogen it is copper nitrate.
