`XCl_(2)("excess")+Ycl_(2) to XCl_(4)+Y darr` ,
`YO underset(gt400^(@))overset(Delta)to (1)/(2)O_(2)+Y`, Ore of Y would be :

A

Siderite

B

Cinnabar

C

Malachite

D

Hornsilver

Text Solution

Verified by Experts

The correct Answer is:
B
`underset(XCl_(2)(SnCl_(2))+underset(Ycl_(2))(HgCl_(2)) to underset(XCl_(4))(SnCl_(4))+underset(Y)(Hg)`
`HgO underset(gt 400^(@)C)overset(Delta)to Hg+(1)/(2)O_(2)`
HgS : Cinnabar
