Help with complete and net ionic equations?

Question

Write the complete and net ionic equations. Indicate the state of the reaction products.

1. Ag2SO4 (aq) + NaNO3

2. CaBr2 (aq) + Na2SO4 (aq)

3. Pb(IO3)2 (aq) + NaOH (aq)

4. K2SO4 (aq) + BaCl2 (aq)

Answer 1

1. Ag2SO4 (aq) + NaNO3 => Ag+ + SO4(2-)(aq) + Na+ + NO3-

2. CaBr2(aq) + Na2SO4(aq) ==> 2NaBr(aq) + CaSO4(s)

3. Pb(IO3)2(aq) + 2NaOH(aq) ==> Pb(OH)2(s) + 2NaIO3(aq)

4. K2SO4 (aq) + BaCl2 (aq) ==> BaSO4(s) + 2KCl(aq)
