NaHCO3 --> Na+ + HCO3-
Ca(NO3)2 --> Ca(2+) + 2NO3-
Al2(CO3)3 --> 2Al(+3) + 3CO3 (-2)

Obviously, you need to figure out how to do these, and I'm sure your textbook has an explanation. Basically, you need to identify the ions which would be formed when each of these dissolves in water. In the first case, NaHCO3 will dissociate into 1 Na+(aq) ion and one HCO3-(aq) ion. Calcium nitrate will form one Ca2+(aq) ion and 2 NO3-(aq) ions...
You need to learn your ions and use that knowledge to allow you to work through these kinds of questions...

which disassociation equation? to use Ksp you have to start with a solid. Ka or Kb is more likely with the compounds you have listed, but without more information I can't help you
