A) \[C{{u}_{2}}S+2C{{u}_{2}}O\xrightarrow[{}]{{}}6Cu+S{{O}_{2}}\]
B) \[Si+{{O}_{2}}\xrightarrow[{}]{{}}Si{{O}_{2}}\]
C) \[F{{e}_{2}}{{O}_{3}}+3C\xrightarrow[{}]{{}}2Fe+3CO\]
D) \[4Fe+3{{O}_{2}}\xrightarrow[{}]{{}}2F{{e}_{2}}{{O}_{3}}\]
Correct Answer: A
Solution :
In a bessemer converter,\[C{{u}_{2}}S\]changes to copper by self-reduction. \[C{{u}_{2}}S+2C{{u}_{2}}O\xrightarrow[{}]{{}}6Cu+S{{O}_{2}}\]
