Question

the reduction of copper oxide by heating carbon 2CuO +C__2Cu +CO2 .In a copper smelter ,how many g of carbon is needed to make 16g of copper​

Answer 1

Answer:

Obtaining metals from metal oxides

Carbon is a non-metal but it is more reactive than some metals. This means that some metals can be extracted from their metal oxides using carbon.

Less reactive metals than carbon can be extracted from their oxides by heating with carbon. In general:

metal oxide + carbon → metal + carbon dioxide

This works for zinc, iron, tin, lead and copper. Copper is the least reactive of these five metals.
