It is the direct combination of two elements or oxidation of copper.
2Cu + O2 = 2CuO
its a synthesis reaction!
AnswerCu + O2 --> CuOIn other words, the elements that reacted were:Oxygen and Copper;forming Copper Oxide
To get the answer just remember that in chemical reactions the total mass of all the parts before the reaction must be the same as the total mass of all the parts after the reaction.
if you mix copper and oxygen you get Copper oxide !
Copper Oxide
Rust? The two different types of bonds between the copper and oxygen in copper oxide are: Copper(II)Oxide CuO Copper(I)Oxide Cu2O
Yes, copper oxide can be obtained by burning copper with oxygen. When copper is heated in the presence of oxygen, it undergoes a chemical reaction to form copper oxide. The resulting copper oxide can be collected and used for various purposes.
Copper Oxide
The oxygen in the reaction is found in the air around you, and forms a synthesis reaction with copper when burned.
It depends what the metal is, but any metal combined with oxygen will be an oxide, for example: Copper + Oxygen = Copper Oxide.
Copper (II) oxide or cupric oxide: CuO.Copper (I) oxide or cuprous oxide: Cu2O.
Copper and oxygen atoms form to create copper oxide. This is a synthesis reaction, and it can be created when copper is burned in a fire.
Cuprous oxide, or copper (I) oxide, Cu2O, is a red powder.Cupric oxide, or copper (II) oxide, CuO, is a black powder.
Copper (II) oxide or cupric oxide: CuO.Copper (I) oxide or cuprous oxide: Cu2O.
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)
"*Cuprous oxide*", or copper (I) oxide, *Cu**2**O*, is a red powder. "**""*Cupric oxide*", or copper (II) oxide, *CuO*, is a black powder.
copper oxide---> copper + oxygen
it's a physical reaction because you can get it back to copper oxide
