WebLower placed metals can be extracted from their compounds by heating with carbon which reduces them. E.g. The oxides of metals which are below carbon can be reduced by heating them with carbon. The carbon removes the oxygen from the metal oxide. Carbon dioxide is formed as well as the metal element: metal oxide + carbon → metal + carbon dioxide. WebTopic Questions.
