WebJul 1, 2015 · Essentially, copper extraction occurs from copper earths, because oxygen (or protons on water) dissolved in the salt oxidizes any metallic compounds in the melt and the chloride in the salts break down any oxides thereby dissolving metallic copper and copper oxide found in ore or slag. Web1. Copper(II) oxide is a black, powdery solid. 2. The gas formed is carbon dioxide. 3. The solid remaining after heating is a pink solid. 4. The solid formed is copper. 5. copper(II) oxide + carbon → copper + carbon dioxide 2CuO + C → 2Cu + CO 2 6. Carbon is more reactive than copper because carbon displaced copper to form carbon dioxide. 7.
