What compounds make up copper? Among the important industrial compounds of copper(I) are cuprous oxide (Cu2O), cuprous chloride (Cu2Cl2), and cuprous sulfide (Cu2S). Cuprous oxide is a red or reddish brown crystal or powder that occurs in nature as the mineral cuprite.
What is formed when copper? Heated copper metal reacts with oxygen to form the black copper oxide. The copper oxide can then react with the hydrogen gas to form the copper metal and water.
How is copper oxide formed? It can be formed by heating copper in air at around 300–800°C: 2 Cu + O2 → 2 CuO. For laboratory uses, pure copper(II) oxide is better prepared by heating copper(II) nitrate, copper(II) hydroxide, or basic copper(II) carbonate: 2 Cu(NO3)2(s) → 2 CuO(s) + 4 NO2(g) + O2(g) (180°C)
