write the metal ion complex (predominant one) for the beakers:

all four beakers contained .1M Ni(NO3)2 6H20, which was a light teal green

to beaker 2, 1mL of 6MNH3 was added, and it turned bright blue

to beaker 3 and 4, 1 mL of 30%en was added and they turned a purple

to beaker 4 lmL of 6MNH3 was added and it remained around the same color


are the answers:
A- Ni(NO3)2 6H20
B- 6M NH3
C-30%en
D-30%en
