Subsequently, one may also ask, is heating copper a physical or chemical change?
A chemical change always produces a new substanceand is usually permanent. A physical change forms no newchemical and is usually temporary. This is when a compoundsplits apart into two (or more) chemicals. eg: coppercarbonate decomposes when heated to form carbon dioxide gasand leave black copper oxide.
Similarly, it is asked, what happens when copper and sulfur are heated?
The liquid sulfur then gets to react with thecopper, and any oxygen that could possibly oxidize thecopper would have to diffuse into the liquid sulfurbefore reaching the copper. However, oxygen quickly reactswith heated sulfur forming sulfur oxides, so it neverreaches the copper wire.
Heated copper metal reacts with oxygen to formthe black copper oxide. The copper oxide can thenreact with the hydrogen gas to form the copper metaland water.
