Expressing Concentration Of Solutions

The extraction of iron from its ore (typically hematite ) in a blast furnace involves reduction reactions at high temperatures. The following reactions occur in the blast furnace:
- Reaction B: This is the reduction of iron(II) oxide to iron, which is a key reaction in the extraction of iron
- Reaction C: This reaction represents the formation of carbon monoxide, which is an essential reducing agent in the blast furnace. |
- Reaction D: This reaction forms calcium silicate (slag), which helps remove impurities like silica from the iron ore.
- Reaction A: This reaction does not occur under typical blast furnace conditions.
The temperature in the blast furnace is not high enough to reduce directly to .
The reduction of typically occurs in multiple steps, and this reaction does not take place as written.
Thus, the correct answer is (A).
