What is the black solid formed when copper carbonate is heated?
This compound is the copper(II) oxide, CuO.
Is copper oxide a solid?
Yes, copper(II) oxide is a solid at standard and room temperature. Copper(I) oxide is also a solid in these conditions as well.
What colour is copper oxide and why?
Copper has two oxides. Copper (I) oxide is red, while Copper (II) oxide is black.
What distinguishes a compound like copper sulfate from an ordinary mixture of copper powder sulfur?
There are two copper oxides. Copper I oxide (Cu2O) and copper II oxide (CuO) both contain copper and oxygen. Copper II oxide is a reddish solid and Copper II oxide is a black solid. Both are insoluble in water. Copper sulfate (CuSO4) contains copper, sulfur, and oxygen. It is most often found in its hydrated form as a blue solid, but allso occurs in its anhydrous form as a white solid. It is soluble in water.
What does copper oxide look like after copper has burned?
Copper oxide appears as a black or dark brown powder after copper has burned.
Is copper II oxide a solid?
Yes it is
What type of substance is black copper oxide powder alkali or base?
Black copper oxide is basic innature.
Why does copper carbonate decompose to make copper 2 oxide not copper 1 oxide?
Because it is easier. The molecular formula of copper carbonate is CuCO3. When it decomposes it loses a CO2 molecule. If it became Copper 1 oxide(Cu2O then it would have to combine with another molecule(releasing O). Instead it becames copper2 oxide(CuO) because that is an easier transition.
What metal forms a black oxide when heated?
copperCopper (cupric) oxide is produced. Therefore, copper is the metal that produces a black oxide when heated.
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)
What is the name of the black coating that forms on the surface of copper?
copper oxide. when it reacts with the oxygen in the air it produces copper oxide
What is the name of the black substance formed on copper?
copper oxide
