$XC{l_2}\,(excess)\,\, + \,\,YC{l_2}\, \to \,\,XC{l_4}\, + \,Y\,\, \downarrow \,\,;$

$YO\,\,\xrightarrow[{ > \,{{400}\,^o}}]{\Delta }\,\frac{1}{2}\,{O_2}\, + \,Y,$ Ore of  $Y$ would be

A

Siderite

B

Cinnabar

C

Malachite

D

Hornsilver

Solution

$\mathop {SnC{l_2}}\limits_{(XC{l_2})} \, + \,\mathop {HgC{l_2}}\limits_{(YC{l_2})} \,\, \to \,\,\,\mathop {SnC{l_4}}\limits_{(XC{l_4})} \, + \,\mathop {Hg}\limits_{(Y)} $

$HgO\,\,\xrightarrow[{ > \,{{400}\,^oC}}]{\Delta }\,Hg\,+\,\frac{1}{2}\,{O_2}$
