The equation is , CuO + 2HNO3 = Cu(NO3)2 + H2O


Since there are two valence states for copper, Cu+ and Cu2+, there are two compounds formed from copper and oxygen:Copper (I) Oxide = Cu2O (equation: 4Cu + O2 --> 2Cu2O)Copper (II) Oxide = CuO (equation: 2Cu + O2 --> 2CuO)


There are two different copper oxide formula's:2Cu + O2 -> 2CuO (black Copper(II) oxide)or4Cu + O2 -> 2Cu2O (red Copper(I) oxide)

Copper oxide consists of copper and oxygen hence the name copper oxide.


copper oxide---> copper + oxygen




Solid copper heated with oxygen in air produces copper (II) oxide. 2Cu(s) + O2(g) + heat --> 2CuO(s)


if you mix copper and oxygen you get Copper oxide !


Oxide is not an element . Copper plus oxygen eaquals copper oxide .Pure copper exposed to oxygen turns greenish .
