The colour of copper(II) oxide is black, while that of copper(I) oxide is red. The green colour you see on the Statue of Liberty is because carbon dioxide in the air reacted with the copper to produce copper(II) carbonate, which is greenish-blue.

What does copper and oxgyen make?
Copper oxide, which is a compound from the two elements copper and oxygen. When copper is exposed to oxygen for a long period of time, it begins turning green. The green is Copper oxide.Copper oxide can refer toCopper(I) oxide (cuprous oxide, Cu2O), a red powder;Copper(II) oxide (cupric oxide, CuO), a black powder. (Source wikipedia)
What do you get if you mix copper and iron?
It forms copper (I) oxide and copper (II) oxide, mostly the (II) oxide that is black. If you talk about what color is emitted a green/turquoise when heated. If in a oxygen-poor atmosphere it melts without oxidising.
Is copper oxide hydrogen?
No. Copper oxide is just copper and oxygen. It is generally green in color and is often seen as weathering or corrosion on copper. Hydrogen is an element and is not part of copper oxide.
Will iron oxide turn copper green?
no
What is the balanced formula for copper plus oxygen-----copper oxide?
There are two different copper oxide formula's:2Cu + O2 -> 2CuO (black Copper(II) oxide)or4Cu + O2 -> 2Cu2O (red Copper(I) oxide)
How does black copper oxide form?
CuCO3 + Heat --> CuO + O2 Green Copper Carbonate when heated will form Copper Oxide and Oxygen

What happens when oygen and copper react?
You get copper (I) oxide which is red and copper (II) oxide that is black. Copper (II) oxide is more stable. In moist air it also forms copper hydroxide and copper carbonate giving the known green color.
Is copper oxide a black solid?
Cu2O (Copper(II) Oxide) is a Red Powder. CuO (Copper(I) Oxide) is a Black Powder.
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)
What colour is copper oxide and why?
Copper has two oxides. Copper (I) oxide is red, while Copper (II) oxide is black.
What does copper oxide look like after copper has burned?
Copper oxide appears as a black or dark brown powder after copper has burned.
Why does a penny turn green in water?
The copper reacts with the oxygen in water to form copper oxide and hydrogen ions. This is copper oxide is a green compound.
What do you get if you mix copper and iron?
It forms copper (I) oxide and copper (II) oxide, mostly the (II) oxide that is black. If you talk about what color is emitted a green/turquoise when heated. If in a oxygen-poor atmosphere it melts without oxidising.
Why does copper turn black when it meets oxygen?
Foolish Fools!, it does infact turn Green! because the oxygen bonds with the copper to form copper oxide, wich is green, it reflects different fractions of light to the copper
What type of substance is black copper oxide powder alkali or base?
Black copper oxide is basic innature.
Is copper oxide hydrogen?
No. Copper oxide is just copper and oxygen. It is generally green in color and is often seen as weathering or corrosion on copper. Hydrogen is an element and is not part of copper oxide.
