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

Question

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 (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

Iron pyrites ⇒ FeS 2 ; Oxidation state of Fe ⇒ +2( x ) Copper glance ⇒ Cu 2 S ; Oxidation state of Cu ⇒ +1( y ) Zincite ⇒ ZnO ; Oxidation state of Zn ⇒ + 2(z) ∴ x+y+z=2+1+2=5

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

Iron pyrites $\Rightarrow F e S_{2};$ Oxidation state of $F e \Rightarrow$
$+ 2 (x)$
Copper glance $\Rightarrow C u_{2} S;$ Oxidation state of $C u \Rightarrow$
$+ 1 (y)$
Zincite $\Rightarrow Z n O;$ Oxidation state of $Z n \Rightarrow + 2 (z)$
$∴ x + y + z = 2 + 1 + 2 = 5$

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

Iron pyrites ⇒FeS2​; Oxidation state of Fe⇒ +2(x) Copper glance ⇒Cu2​S; Oxidation state of Cu⇒ +1(y) Zincite ⇒ZnO; Oxidation state of Zn⇒+2(z) ∴x+y+z=2+1+2=5
