2Cu + O2 → 2CuO
In this reaction, two moles of copper react with one mole of oxygen gas to produce two moles of copper (II) oxide. The reaction typically occurs at elevated temperatures, and the heat produced during the reaction helps to drive the formation of the oxide. Copper (II) oxide is a black, powdery substance that is insoluble in water. It is commonly used in various industrial applications, such as as a pigment in ceramics and as a catalyst in chemical reactions.
