Solution: The first metal to be prepared from its ore was copper, perhaps as early as 6000 BC in the Middle East. The ore, which contained copper oxide, was heated with charcoal, which was prepared by the incomplete burning of wood and is mainly elemental carbon C (s). Later, iron and tin were prepared the same way. Write the chemical equations for the preparation of these metals. Assume the ores to be CuO (s), SnO2 (s), and Fe2O3 (s).
