Answer»  Explanation: Both are p-type semiconductors, but Cu2O has a band gap of 2eV whereas CuO has a band gap of 1.2 eV — 1.9 eV. Cu2O is obtained by oxidation of copper metal or reduction of copper(II) SOLUTIONS with sulfur oxide, whereas CuO is obtained by pyrometallurgical PROCESSES USED to extract copper from ORES.  |
