Question
Metals less reactive than carbon can be extracted using...A:ElectrolysisB:Displacement with a more reactive metalC:No extraction needed they are found as native metalsD:Reduction with carbon
Solution
The correct answer is D: Reduction with carbon. Metals that are less reactive than carbon can be extracted from their ores by reduction with carbon. The carbon is able to remove the oxygen from the metal oxide in a process called reduction, leaving the metal behind.
