A) \[1:1\]
B) \[1:2\]
C) \[2:1\]
D) none of these
Correct Answer: B
Solution :
100Ml of \[1M\,\,AgN{{O}_{3}}\equiv 0.1\,mol\,AgN{{O}_{3}}\] 100 ml of \[CuS{{O}_{4}}=0.1mol\,CuS{{O}_{4}}\] \[\underset{\begin{smallmatrix} 2\,mol \\ 0.1\,mol \end{smallmatrix}}{\mathop{2AgN{{O}_{3}}}}\,+\underset{\begin{smallmatrix} 1\,mol \\ 0.05\,mol \end{smallmatrix}}{\mathop{{{H}_{2}}S}}\,\xrightarrow{{}}A{{g}_{2}}S+2HN{{O}_{3}}\] \[\underset{\begin{smallmatrix} 2\,mol \\ 0.1\,mol \end{smallmatrix}}{\mathop{CuS{{O}_{4}}}}\,+\underset{\begin{smallmatrix} 1\,mol \\ 0.05\,mol \end{smallmatrix}}{\mathop{{{H}_{2}}S}}\,\xrightarrow{{}}CuS+{{H}_{2}}S{{O}_{4}}\] \[\therefore \]Ratio of the amounts of \[{{H}_{2}}S\] obtained \[=0.05:0.1=1:2\]
