How to write balanced net ionic equations?

I recently did a lab in chemistry about determining the activity series and one of the post lab questions is about writing the balanced net ionic equations. Can someone help me work out the first few and tell me how to do this? Thank you!

1. Mg(s) + Cu(NO3)2(aq) -%26gt; ?

2. Pb(s) + AgNO3(aq)-%26gt; ?

3. Zn(s) + Pb(NO3)2(aq)-%26gt; ?How to write balanced net ionic equations?
Mg + Cu2+ = Mg2+ + Cu

Pb + 2 Ag+ = Pb2+ + 2 Ag

Zn + Pb2+ = Zn2+ + Pb
