copper oxide reduced by carbon equation

GCSE CHEMISTRY

2017-2-21 · copper(II) oxide + carbon copper + carbon dioxide. 2CuO (s) + C (s) 2Cu (s) + CO 2(g) Carbon is oxidised by gaining oxygen to form carbon dioxide. Copper (in CuO) is reduced by losing oxygen to form copper metal. Note that copper has changed from Cu 2+ (in CuO) to Cu (s) and so has gained electrons.
