A) \[Fe\xrightarrow[{}]{C{{l}_{2}}.heat}FeC{{l}_{3}}\xrightarrow[{}]{heat,air}FeC{{l}_{2}}\xrightarrow[{}]{Zn}Fe\]
B) \[Fe\xrightarrow[{}]{{{O}_{2}},heat}F{{e}_{3}}{{O}_{4}}\xrightarrow[{}]{CO,{{600}^{o}}C}FeO\xrightarrow[{}]{CO,{{700}^{o}}C}Fe\]
C) \[Fe\xrightarrow[{}]{dil\,{{H}_{2}}S{{O}_{4}}}FeS{{O}_{4}}\xrightarrow[{}]{{{H}_{2}}S{{O}_{4}},{{O}_{2}}}F{{e}_{2}}{{(S{{O}_{4}})}_{3}}\xrightarrow[{}]{heat}Fe\]
D) \[Fe\xrightarrow[{}]{{{O}_{2}},heat}FeO\xrightarrow[{}]{dil\,{{H}_{2}}S{{O}_{4}}}FeS{{O}_{4}}\xrightarrow[{}]{heat}Fe\]
E)
Correct Answer: B
Solution :
\[3Fe+2{{O}_{2}}\xrightarrow[{}]{\Delta }F{{e}_{3}}{{O}_{4}}\] \[F{{e}_{3}}{{O}_{4}}+CO\xrightarrow[{}]{{{600}^{o}}C}3FeO+C{{O}_{2}}\] \[FeO+CO\xrightarrow[{}]{{{700}^{o}}C}Fe+C{{O}_{2}}\]You need to login to perform this action.
