Cooper get oxidised to copper oxide when burned in air.
copper oxide
Is it Solid?
sodium
Copper is a chemical element. It can be a compound but copper is usually known as a chemical element.
Copper Carbonate.
It depends on what you added to the methanol before you put the heated copper wire into the methanol. The heated copper wire acted as a catalyst to speed up the reaction between the methanol and the other substance. Copper itself does not react with methanol.
copper sulfide
Copper sulfide is a compound of copper and sulfur. It occurs naturally and is commonly found in minerals such as chalcopyrite, bornite, and chalcocite. Copper sulfide is an important source of copper for the production of metal and various industrial applications.
This compound is the iron(III) oxide, Fe2O3.
carbon dioxide
Is it Solid?
sodium
Magnesium oxide?
The black solid formed when copper carbonate is heated is copper oxide (CuO). This reaction occurs because the carbonate ion is decomposed upon heating, leaving behind the copper in its oxide form.
Copper Oxide
the element was copper and the new black compound formed was copper oxide.
Copper sulfate crystals are a compound, not an element. The compound is formed by combining copper, sulfur, and oxygen atoms.
Water (H2O) is formed when hydrogen is burned by oxygen
