The correct formula for copper(I) cyanide is CuCN.
The formula for copper(II) oxide is CuO. This is the commonly met black powder.
Copper(I) oxide also exists. This is a red powder, and its formula is Cu2O where the 2 should be a subscript.
Copper [Cu] atomic number 29, is an element.
Copper(I) Oxide: Cu2O (cuprous oxide)
or
Copper(II) Oxide: CuO (cupric oxide)
it can be both.
Metallic copper is an element (Cu) so there is no formula.
Symbol: Cu
CuH2PO4 - this is wrong! The correct answer is: Cu(H2PO4)2
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper (II) sulfate.
CuO2 is the chemical formula for copper dioxide.
The chemical formula for copper (I) iodide is CuI, and for copper (II) iodide is CuI2. Copper (I) iodide is the more common of the two.
Cu(No3)2 is the formula for copper nitrate compund
The copper(II) fluoride has the formula CuF2.
The copper(II) fluoride has the formula CuF2.
Copper is Cu. The (I) means there is only 1 Cu atom. Cyanide is CN- Therefore the formula for Copper (I) Cyanide or Copper I Cyanide is: CuCN
Copper Hydroxide
the correct name for the chemical formula is copper sulfate.
No :- CuCl is correct.
copper sulfate
Copper does not form +3 oxidation number. So there cant be a formula like that.
It would be CuF3 but this compound does not exist. Copper(II) fluoride, CuF2 exists, and K3CuF6 exists and contains copper III.
CuH2PO4 - this is wrong! The correct answer is: Cu(H2PO4)2
It is CuF2 (where the 2 should be a suffix, but this site does not accommodate such niceties!)
It is CuF2 (where the 2 should be a suffix, but this site does not accommodate such niceties!)
