How is copper oxide made?

Answer 1

2Cu + O2 --> 2CuO

In air and water, or where oxygen reacts with copper. Google verdigris.
There are several methods,

"Heating Copper metal in air.

"Heating Copper carbonate.

"Heating Copper hydroxide.

"Reacting Cuprous chloride with KMnO4.

Answer 2

Copper oxide can be heated very strongly to make it decompose into Copper and Oxygen, but this procedure need high amount of heat. So, another efficient method used is, to react copper oxide with a strong reducing agent such as Ammonia, Hydrogen or Carbon monoxide. This procedure requires lesser heat than the first one.

Answer 3

Copper(II) oxide, CuO:

- oxidation of copper

- thermal decomposition of copper salts

Copper(I) oxide, Cu2O:

- oxidation of copper

Answer 4

hydrogen sulfide (H2S), is bubbled through solutions of Cu(II) salts

or when solid copper and sulfur (hot sulfur gas) are heated together

Cu + S -> CuS

Answer 5

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

Answer 6

Copper hydroxide is formed by running a current through two copper electrodes into a solution of magnesium sulfate. If you don't mind me asking, what do you need it for?

Answer 7

Compounds are formed by chemical reactions.

Answer 8

CuO + H2---- Cu +H2O
