Question

Net Ionic equations for..

1. Co(NO3)2 + NH3 --> ??

2. Cu(NO3)2 + NH3 --> ??

3. Ni(NO3)2 + NH3 --> ??

I can balance equations, I just don't know what goes on the products side.

Answer 1

Just products?
Are you studying complex formation? Co is known with both 6 and 4 NH3 complexed. Ni is the same. Cu is square planar (with NH3) and coordination number of 4.
1. Co(NH3)₆⁺² + NO3^-
2. Cu(NH3)4^+2 + NO3^-
3. Ni(NH3)6^+2 + NO3^-
