What is the color of copper oxide?
There are two copper oxides, differing in color:if it is black powder, then it is copper(II) oxide CuO (cupric, more common, as in the mineral 'tenoriet')if it is red powder, then it is copper(I) oxide Cu2O (cuprous oxide, as in mineral the 'cupriet' and it occurs in 'Benedict's test' on reducing sugars)
When copper is heated in air what colour is the copper oxide formed?

What is the valency of cupper?
Its Valency = 2the formula being CuOThe copper donates two electrons to the oxygen and forms one ionic bond.Added:There are two copper oxides, differing in color:if it is black powder, then it is copper(II) oxide CuO (cupric, more common, as in the mineral 'tenoriet')if it is red powder, then it is copper(I) oxide Cu2O (cuprous oxide, as in mineral the 'cupriet' and it occurs in 'Benedict's test' on reducing sugars)
What is the copper oxide formula?
Copper oxide has two different forms. The first is a red power, Copper (I) oxide. Otherwise known as cuprous oxide or Cu2O. The second is a black powder, Copper (II) oxide. This is also known as cupric oxide or CuO.
What happens when cupric oxide is strongly heated?
It should decomose into Cu(I)O and water. Cu(II)(HO)2 -----> Cu(I)O + H2O Keep in mind that copper hydroxide is a fairly strong bass so be careful when handling it. But if you have proper eye protection and basic lab skills you should be fine.
What Is the name of the compound formed form the chemical reaction between copper and oxygen?
Copper (II) oxide or cupric oxide: CuO.Copper (I) oxide or cuprous oxide: Cu2O.
When copper reacts with oxygen is the acid formed a acid or a base?
Cuprous and cupric oxide are base forming oxides, only nonmetals can have acidic oxides, though some other metal (amphoteric) oxides are also (mainly weak) acid forming oxides.
When oxygen changes metals like copper and iron it makes?
An oxide of that metal. Depending on how many atoms fo each mix, you will get different oxides. For example, copper and oxygen can form cuprous oxide (Cu2O) or cupric oxide (CuO)

How can you be sure that the oxides of copper are different from compounds?
Oxides of copper are compounds !
Does copper and steam react?
No copper kettles are coated with special chemicals which prevents steam reacting with it just like aluminum forms an oxide layer which prevents it from further reacting. If no layer were put on the kettle it would turn greenish because copper would have reacted................. Hope I was useful ;-) Kyle.
What is the copper oxide formula?
Copper oxide has two different forms. The first is a red power, Copper (I) oxide. Otherwise known as cuprous oxide or Cu2O. The second is a black powder, Copper (II) oxide. This is also known as cupric oxide or CuO.
How can we clean copper oxide?
Copper oxides are soluble in acids.
What color is copper when it oxides?
blue
What happen when copper is burn?
The copper oxides (CuO and Cu2O) are obtained.
