Explanation / Answer

it is against chegg policy to post multiple questions in a single post

i will solve only 2

1)[Ba2+][F-]^2=1.8*10^-7

or [Ba2+]=1.758*10^-2 M

3)solubility=5.93*1000/(10*461)

= 1.286*10^-3 M.s

so [Pb]=1.286*10^-3

[I2]=2*1.286*10^-3

so ksp=[Pb][I-]^2

=8.5*10^-9

4)F is a weak field ligand and NO7 is a strong field ligand so NO7 will cause lage distortion in energy,so

[Cr(NO7)4]- is paramagnetic
