Vedclass · Answer

(C) The correct formula is $A_3(BC_4)_2$.For a neutral compound,the sum of the oxidation states of all atoms must be zero.Let the formula be $A_x(BC_4)_y$. The oxidation state of the group $(BC_4)$ is $(+5) + 4(-2) = 5 - 8 = -3$.To make the compound neutral,the total charge must be $x(+2) + y(-3) = 0$.For $x=3$ and $y=2$,we get $3(+2) + 2(-3) = 6 - 6 = 0$.Thus,the formula is $A_3(BC_4)_2$.

$A, B,$ and $C$ are three elements forming a compound in which their oxidation states are $+2, +5,$ and $-2$ respectively. If the compound is neutral,which of the following represents the formula of the compound?
