Copper oxide is produced by heating copper and oxygen together to produce a black solid. This solid is copper oxide.


copper+oxygen-----copper oxide


Word equation:copper (II) carbonate --> copper oxide + carbon dioxideSymbol equation:CuCO3 --> CuO +CO2


When sulphide ore is heated in air it is converted into copper oxide and SO2 is left. Again, copper oxide is then reduced to copper on heating( for equation, refer 10th CBSE text, pg no. 51)


HCL and copper oxide = Copper chloride+water


Word equation Copper Carbonate ----> Copper Oxide and Carbon dioxide Balanced equation CuCO3 ----> CuO + CO2


The chemical formula for copper oxide is CuO.


The oxidation of copper to form copper oxide is an example of a chemical change involving copper. Copper can oxidise to cupric oxide (copper(II)oxide) which is a black powder or oxidise to cuprous oxide (copper(I)oxide) which is a yellow/ red colour and quickly degrades to copper(II) oxide in humid air. The chemical equation for the oxidation of copper to copper(I)oxide is: 4Cu + O2 = 2Cu2O The chemical equation for the oxidation of copper to copper(II) oxide is: 2Cu + O2 = 2CuO


By using Electrolysis. No, not electrolysis. By heating copper in air , it will form copper oxide.Even reaction with steam gives copper oxide heat (O2) Copper ---------------> copper oxide Copper + Steam (H2O) ---------> copper oxide Copper + Water ---------> copper hydroxide


This will depend upon which version of copper oxide you have - copper I oxide or copper II oxide. For copper I oxide: H2SO4 + Cu2O --> Cu2SO4 + H2O For copper II oxide: H2SO4 + CuO --> CuSO4 + H2O



Copper hydroxide will decompose under strong heating to form copper(II)oxide and water.


The carbon will react with the oxygen in the copper oxide, forming carbon dioxide and leaving behind the copper.


I assume you mean copper(II) oxide, which is black, and not copper(I) oxide which is orangey-red.copper oxide + sulfuric acid --> copper sulfate + water.


This is one way of extracting copper from copper (II) oxide. 2CuO + C -> CO2 + 2Cu


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


The ionic equation for a reaction between hydrochloric acid and copper oxide is: 2H+ + O2- -> H2O


The word equations for the reaction between copper and oxygen is copper+oxygen= copper oxide.


Laboratory preparation of copper oxide: copper salt such as CuSO4 reacts with alkali (NaOH) to generate Cu(OH)2, and then Cu(OH)2 is decomposed by heating to prepare CuO. ใ€€ใ€€CuSO4+2NaOH==Cu(OH)2โ†“+Na2SO4 ใ€€ใ€€Cu(OH)2=โ–ณ=CuO+H2O Heat copper (Cu) to make copper react with oxygen (O2) to generate oxidation Copper (CuO). ใ€€ใ€€2Cu+O2==2CuO Copper oxide can be prepared by heating metallic copper in air or decomposing copper hydroxide, copper nitrate, basic copper carbonate, etc.

Metallic copper reacts with an excess of oxygen to form copper(II) oxide or with a deficiency of oxygen to form copper(I) oxide.


There are two copper oxides. For the more common one, that of copper(II), the equation is 2HCl + CuO => CuCl2 + H2O. For copper(I) oxide, the equation is Cu2O + 2 HCl => 2 CuCl + H2O.
