A) \[C{{O}_{2}}\]
B) \[CO\]
C) limestone
D) aluminium
E) hydrogen
Correct Answer: B
Solution :
In the extraction of Fe in the blast furnace, the purified oxide ore is reduced to spongy iron by CO at the top of blast furnace, as follows \[F{{e}_{2}}{{O}_{3}}+3CO\xrightarrow{{}}\underset{\begin{smallmatrix} spongy \\ \,\,\,\,\,iron \end{smallmatrix}}{\mathop{2Fe}}\,+3C{{O}_{2}}\] \[CO\]acts as a reducing agent. It occurs in reduction zone at\[400-700{}^\circ C\].
