A) \[C{{u}_{2}}S\to C{{u}_{2}}O\]
B) \[\operatorname{CaC}{{O}_{3}}\to CaO\]
C) \[ZnS\,\,\to \,\,Zn\]
D) \[PbS\to Pb\]
Correct Answer: D
Solution :
\[PbS \xrightarrow{{}} Pb \left( Roasting + Self-reduction \right)\] \[{{\operatorname{Cu}}_{2}}S\,\,\xrightarrow{{}} C{{u}_{2}}\,O \left( Roasting \right)\] \[\operatorname{CaC}{{O}_{3}} \xrightarrow{{}} CaO \left( Roasting + Carbon reduction \right)\]\[\operatorname{ZnS} \xrightarrow{{}} Zn \left( Roasting + Carbon reduction \right)\]You need to login to perform this action.
