How do you get powdered charcoal from a mixture of copper oxide and powdered charcoal?
To obtain powdered charcoal from a mixture of copper oxide and powdered charcoal, you can use a reduction reaction. Heat the mixture in a furnace or with a suitable heat source, as copper oxide will react with the charcoal (carbon) to form copper and carbon dioxide. The copper will be produced as a metal, leaving behind the powdered charcoal. After cooling, you can separate the unreacted charcoal from the copper.
