A) \[O\to B\]
B) \[O\to A\]
C) \[A{{g}_{2}}O+{{H}_{2}}O+2{{e}^{-}}\xrightarrow{{}}2Ag+2O{{H}^{-}}\]
D) \[Fe(III)\]
Correct Answer: C
Solution :
\[A>C>B\] Hardness in \[C>B>A\] of \[F{{e}_{0.93}}{{O}_{1.00}}\] Therefore, hardness in \[2C{{u}_{2}}O+C{{u}_{2}}S\xrightarrow{{}}6Cu+S{{O}_{2}}\] \[2C{{u}_{2}}S+3{{O}_{2}}\xrightarrow{{}}2C{{u}_{2}}O+S{{O}_{2}}\] \[2CuFe{{S}_{2}}+{{O}_{2}}\xrightarrow{{}}C{{u}_{2}}S+FeS+S{{O}_{2}}\] required \[2FeS+3{{O}_{2}}\xrightarrow{{}}2FeO+2S{{O}_{2}}\] Therefore. \[q=\Delta U\] required \[O\to D\]You need to login to perform this action.
