1. The problem statement, all variables and given/known data
Write the balanced molecular equation, complete ionic, and net ionic equation for each of the following:

I'm pretty sure I'm doing these correctly, but I just wanted to make sure:

a) -- molecular equation
b) -- complete ionic equation
c) -- net ionic equation

1) HNO3 + Al(OH)3 --> ??

a) 3HNO3 (aq) + Al(OH)3 (s) --> 3H2O (l) + Al(NO3)3 (aq)

b) H+ + NO3- + Al(OH)3 (s) --> 2H2O (l) + Al3+ + NO3-

c) 3H+ + Al(OH)3 (s) --> 3H2O (l) + Al3+

2) Fe(OH)3 (s) + HNO3 --> ??

a) Fe(OH)3 (s) + 3HNO3 (aq) --> Fe(NO3)3 (aq) + 3H2O (l)

b) Fe(OH)3 (s) + 3H+ + NO3- --> Fe3+ + NO3- + 3H2O (l)

c) Fe(OH)3 (s) + 3H+ --> Fe3+ + 3H2O (l)

3) HC2H3O2 + KOH --> ??

a) HC2H3O2 (aq) + KOH (aq) --> H2O (l) + KC2H3O2 (aq)

b) H+ + C2H3O2- + K+ + OH- --> H2O (l) + C2H3O2- + K+

c) H+ + OH- --> H2O (l)

4) strontium hydroxide and hydroiodic acid --> ??

a) Sr(OH)2 (s) + 2HI (aq) --> SrI2 (aq) + 2H2O (l)

b) Sr(OH)2 (s) + 2H+ + I- --> Sr2+ + I- + 2H2O (l)

c) Sr(OH)2 (s) + 2H+ --> Sr2+ + I- + 2H2O (l)

5) Ca(OH)2 + HCl --> ??

a) Ca(OH)2 (s) + 2HCl (aq) --> CaCl2 (aq) + 2H2O (l)

b) Ca(OH)2 (s) + 2H+ + Cl- --> Ca+ + Cl- + 2H2O (l)

c) Ca(OH)2 (s) + 2H+ --> Ca+ + 2H2O (l)

No such thing as Ca+

All your complete ionic equations list only one anion. That's not necesarilly wrong, but it will be better IMHO to list them all, so that side of the equation is neutral.
