The chemical equation Cu2S + O2 -> 2CuO + SO2

Detailed information about the chemical equation: This chemical equation illustrates the reaction process between copper (II) sulfide (Cu₂S) and oxygen (O₂) to produce copper (II) oxide (2CuO) and sulfur dioxide (SO₂).

Reaction conditions: This is a redox reaction, which occurs at high temperatures.

Reaction process: When copper (II) sulfide is heated with oxygen, it reacts to produce copper (II) oxide and sulfur dioxide. Copper (II) oxide is a black solid, while sulfur dioxide is a pale yellow gas.

Observed phenomena: The color change of the solid from the black of copper (II) oxide to the pale yellow of sulfur dioxide, along with the generation of heat, indicates the occurrence of the chemical reaction.
