(A) Na 4[ oversetxFe ( CN )5( NOS )] (+1) 4+ x +(-1) 5+(-1) 1=0 x =+2 (B) Na 4[ oversetyFe O 4] (+1) 4+ y +(-2) 4=0 y =+4 (C) [ oversetzFe 2( CO )9] 2 z +0 × 9=0 z =0 so ( x + y + z )=+2+4+0 =6

Q. The oxidation states of iron atoms in compounds (A), (B) and (C), respectively, are $x, y$ and $z$ . The sum of $x, y$ and $z$ is______.

$(A) N a_{4} [F e (CN)_{5} NOS)] (B) N a_{4} [F e O_{4}] (C) [F e_{2} (CO)_{9}]$

(A) $N a_{4} [F e x (CN)_{5} (NOS)]$

$(+ 1) 4 + x + (- 1) 5 + (- 1) 1 = 0$

$x = + 2$

(B) $N a_{4} [F e y O_{4}]$

$(+ 1) 4 + y + (- 2) 4 = 0$

y $= + 4$

(C) $[F e z_{2} (CO)_{9}]$

$2 z + 0 \times 9 = 0$

$z = 0$

so $(x + y + z) = + 2 + 4 + 0$

$= 6$

$(A) N a_{4} [F e (CN)_{5} NOS)] (B) N a_{4} [F e O_{4}] (C) [F e_{2} (CO)_{9}]$

(A) $N a_{4} [F e x (CN)_{5} (NOS)]$

$(+ 1) 4 + x + (- 1) 5 + (- 1) 1 = 0$

$x = + 2$

(B) $N a_{4} [F e y O_{4}]$

$(+ 1) 4 + y + (- 2) 4 = 0$

y $= + 4$

(C) $[F e z_{2} (CO)_{9}]$

$2 z + 0 \times 9 = 0$

$z = 0$

so $(x + y + z) = + 2 + 4 + 0$

$= 6$
