The copper oxide can then react with the hydrogen gas to form the copper metal and water. When the funnel is removed from the hydrogen stream ... Webthe increase of relative humidity of the air from 0 to 30% causes an increase of the oxidation rate about 50% at 30°C and about 30% at 45°C. In this study, the oxidation behavior of pure copper has been investigated with variables including temperature, oxygen pressure, and water vapor pressure by means of

Cu 2 O degrades to copper(II) oxide in moist air. Structure. Cu 2 O crystallizes in a cubic structure with a lattice constant a l fcc sublattice, the oxygen atoms in a bcc sublattice. One sublattice is shifted by a quarter of the body diagonal.
