Worked Solution & Example Answer:Iron ore contains iron oxide - Edexcel - GCSE Chemistry - Question 3 - 2018 - Paper 1
Step 1
In this reaction
Answer
The correct choice is C: iron oxide is reduced.
In this reaction, iron oxide (FeO or Fe2O3) is being reduced when it reacts with carbon (C) to form iron (Fe) and carbon dioxide (CO2). Reduction is a process in which a substance gains electrons or decreases its oxidation state. Here, the iron in iron oxide is reduced from a higher oxidation state to a lower one, resulting in the formation of elemental iron.
