A) the central metal ion only B) coordination and steric numbers C) the ligands D) the primary and secondary valencies E) the central metal ion and the ligands bonded to it 3) How many d electrons are in the cobalt ion of K_3[Co(CN)_6]? A) 6 B) 7 C) 4 D) 5 E) 3 4) The correct name for [Ni(NH_3)_6](NO_3)_3 is. A) hexaamminenickel (III) trinitrate B) hexaamminenickel (III) nitrate C) hexaamminenickel (II) nitrate D) dinitrohexaamminenickel (II) E) dirutrohexaamminenickelate (III)

Answer 1

1) LEWIS ACID BECAUSE IT CAN ACCEPT APAIR OF ELECTRON FROM THE LIGAND.

2) THE CENTRAL MEAL ION AND THE LIGABDS BODED TO IT

3) 6

BECASUETHE OXIDATION SATE OF COBLAT IN THAT COMPLEX IS +3.HENC E THE valence CONFIGURATION BECOMES 3d^6

4)B) hexaamminenickel(III)nitrate
