Likewise, what happens when copper reacts with Sulphur?
The liquid sulfur then gets to react withthe copper, and any oxygen that could possibly oxidize thecopper would have to diffuse into the liquid sulfurbefore reaching the copper. However, oxygen quicklyreacts with heated sulfur forming sulfuroxides, so it never reaches the copper wire.
Similarly, is copper sulfide a precipitate? It occurs in nature as the dark indigo blue mineralcovellite. It is a moderate conductor of electricity. A blackcolloidal precipitate of CuS is formed when hydrogensulfide, H2S, is bubbled through solutions ofCu(II) salts.
In respect to this, is heating of copper and Sulphur a chemical change?
When heated together, copper and sulfurcombine to form a sulfide of copper. The excesssulfur vaporizes to form gaseous sulfur, whichescapes from the crucible. When the hot sulfur gas reachesthe air, it reacts with oxygen to produce gaseous oxides ofsulfur (mainly sulfur dioxide, SO2).
What happens when copper is heated?
Heated copper metal reacts with oxygen to formthe black copper oxide. The copper oxide can thenreact with the hydrogen gas to form the copper metal andwater. When the funnel is removed from the hydrogen stream, thecopper was still be warm enough to be oxidized by the airagain.
