Q. The oxidation state of metal in iron pyrites, copper glance and zincite are $x , y$ and $z$ respectively. Find the value of $x+y+z$

General Principles and Processes of Isolation of Elements

Solution:

Iron pyrites $\Rightarrow FeS _2 ; $ Oxidation state of $Fe \Rightarrow$
$+2( x )$
Copper glance $\Rightarrow Cu _2 S ;$ Oxidation state of $Cu \Rightarrow$
$+1( y )$
Zincite $\Rightarrow ZnO ;$ Oxidation state of $ Zn \Rightarrow + 2(z)$
$\therefore x+y+z=2+1+2=5$
