A) \[B{{r}^{-}}\]
B) \[50mL\]
C) \[1200mL\]
D) \[30mL\]
Correct Answer: B
Solution :
\[-152\,kJ\,\,mo{{l}^{-1}}\]\[-76\,kJ\,mo{{r}^{-1}}\] ??.(i) \[5mL\]\[A{{s}_{2}}{{S}_{3}}\] ??.(ii) Eq. (i) can be split as \[2Ag+2HCl+(O)\xrightarrow{{}}2AgCl+{{H}_{2}}O\]\[2Zn+{{O}_{2}}\xrightarrow{{}}2ZnO\] \[2Zn+{{O}_{2}}\xrightarrow{{}}2ZnO\]\[N{{i}_{2}}{{O}_{2}}(s)+{{H}_{2}}O(l)+2{{e}^{-}}2NiO(s)+2O{{H}^{-}}\] \[{{E}^{o}}=+0.40V\] \[FeO(s)+{{H}_{2}}O(l)+2{{e}^{-}}Fe(s)+2O{{H}^{-}};\] \[{{E}^{o}}=-8.87V\]You need to login to perform this action.
