easy
Sulphide ores are common for the metals
A
$Ag, Cu$ and $Pb$
B
$Ag, Cu$ and $Sn$
C
$Ag, Mg$ and $Pb$
D
$Al, Cu$ and $Pb$
Solution
Following are the sulfide ores of the metals:
For $Ag$, it is Argentite $\left( Ag _2 S \right)$.
For $Pb$, it is Galena ( $PbS )$.
For $Cu$, it is Copper glance $\left( Cu _2 S \right)$.
