Find the number of unpaired electrons in each case
`[Mn(CN)_(6)]^(3-)=x" "[FeF_(6)]^(3-)=t`
`[MnCl_(6)]^(3-)=y" "[CoF_(6)]^(3-)=u`
`[Fe(CN)_(6)]^(3-)=z" "[Co(H_(2)O)_(3)F_(3)]=v`
Hence, find the correct relationship between x, y, z, t, u, v

Options

A. `y-u=v`
B. `y^(2)+(x+z)^(2)=t^(2)+v^(2)`
C. `x^(2)+ z-t=y^(2)-u^(2)+v^(2)`
D. `x+y+z+t+u gt u^(2)`

Answer

A, B, C

Explanation

x=2, y=4,z=1,t=5,u=4,v=0.
