Question

C. A compound contains atoms of three
elements A, B and C. If the oxidation
state of A is +2, B is +5 and that of C is
-2, the compound is possibly represented
by
a. A, (BC),
b. A, (BC)
c. A, (B,C),
d. ABC
2​

Answer 1

Answer:

A3(BC4)8 or A(BC3)2

Explanation:

Let the compound be AxByCz

Given oxidation states of A,B,C are +2,+5,-2

So (+2)x+(+5)y+(-2)z=0

2x+5y-2z=0

Restricting it to conditions that maximum oxidation state could be -3 or +8

So (x,y,z) are (1,2,6) or (3,2,8)
