A) \[F{{e}_{2}}{{O}_{3}}+3C\to 2Fe+3CO\]
B) \[FeO+Si{{O}_{2}}\to FeSi{{O}_{3}}\]
C) \[F{{e}_{2}}{{O}_{3}}+3CO\to 2Fe+3C{{O}_{2}}\]
D) \[CaO+Si{{O}_{2}}\to CaSi{{O}_{3}}\]
Correct Answer: C
Solution :
[c] \[3F{{e}_{2}}{{O}_{3}}\to 2F{{e}_{3}}{{O}_{4}}+{{O}_{2}}\] \[F{{e}_{3}}{{O}_{4}}+CO\to 3FeO+C{{O}_{2}}\] \[FeO+CO\to Fe+C{{O}_{2}}\]
