What is the name of the black substance formed on copper?
copper oxide
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 color is calcium oxide?
colorless solution or white powder
What happens when you heat copper sulphate over a Bunsen burner?
I think it becomes a black liquid which, when it cools becomes a black powder. it also bubbles and gives off a gas (oxygen I think) that means that the copper sulfate had the oxygen removed making it copper sulfide. (I'm not entirely sure but this is what happened in the practical. Cheers.
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 name of the black substance formed on copper?
copper oxide
What does copper oxide look like after copper has burned?
Copper oxide appears as a black or dark brown powder after copper has burned.
What is the substance in the air that causes copper to turn black when in contact with fire?
The substance in the air is oxygen. Copper + oxygen= copper oxide.
What is observed when air is passed over heated copper powder?
The copper becomes black!
Is Copper oxide a liquid?
No, it is either a red powder (cuprous oxide) or a black powder (cupric oxide)

If a light green powder is heated in a test tube A gas is given off while the solid becomes black In which classification of matter does the green powder belong?
The green powder is copper (2) carbonate. When heated it decomposes to give copper (2) oxide (which is black) and carbon dioxide . It is a compound.
Why the colour of heated copper powder becomes black when air is passed over it?
the copper reacts with 02 in the air to make copper oxide, which is black 2Cu+O2--> 2Cuo
When a metal powder is heated in open dish it turns black which metal is that?
The metal might be copper. When copper is heated, it reacts with oxygen in air forming copper oxide which is black in colour.
What is the formula of copper (II) oxide?
The formula for copper(II) oxide is CuO. This is the commonly met black powder. Copper(I) oxide also exists. This is a red powder, and its formula is Cu2O where the 2 should be a subscript.
How do you convert Newtons to black powder?
I don't think you can because Newton is a unit of measurement of Force while black powder is a substance used in guns.
