The number of total possible stereoisomers for [Pd(NH$$_2$$ - CH(CH$$_3$$) - CO$$_2^{-}$$)$$_2$$]$$^0$$ is?

The total number of possible isomer for the complex compound : $$[Cu(NH_3)_4] [PtCl_4]$$

How many of the following reactions/ statements are correct ?
(I) $$\displaystyle CrO_{5}$$ shows blue colour in organic solvent but in aq. solution blue colour fades because $$\displaystyle CrO_{5}$$ decomposes to $$\displaystyle Cr^{3+}$$ and $$\displaystyle O_{2}$$
(II) $$\displaystyle [Co(SCN)_{4}]^{2-}$$ shows blue colour in aq. solution 
(III) The pink ppt of $$\displaystyle Co(OH)_{2}$$ converts slowly to brown ppt $$\displaystyle Co(OH)_{3}$$ on exposure to air while green ppt of $$\displaystyle Ni(OH)_{2}$$ can be black $$\displaystyle Ni(OH)_{3}$$ with an oxidising reagent like NaOCI only

In which of the following molecules/species, all following characteristics are found?
(a) Tetrahedral hybridisation.
(b) Hybridisation can be considered to have taken place with the help of empty orbital(s).
(c) All bond lengths are identical, i.e., all $$A - B$$ bond lengths are identical.
