Reactivity of metals
Question
- A. Oxygen is added to the metal.
- B. Carbon is oxidised.
- C. The metal oxide is converted to a metal and carbon dioxide.
- D. The metal is converted to a metal oxide.
Answer
The metal oxide is converted to a metal and carbon dioxide.
Explanation
During the reduction process, the metal oxide loses oxygen and is transformed into the pure metal, while carbon is oxidised to carbon dioxide.
Common mistake
Misunderstanding Reactivity and Extraction
Students often think that all metals can be extracted from their ores using carbon, regardless of their reactivity.
Remember that only metals less reactive than carbon can be extracted from their oxides by reduction with carbon. More reactive metals require different extraction methods.
