How do you write the unionized, total ionic and net ionic equations?

Question

For these reactions that take place when solutions of the following substances are mixed

a. sodium iodide and silver nitrate -----> sodium nitrate + silver iodide

b. sodium sulfate and barium chloride ----> sodium chloride + barium sulfate

c. barium carbonate and hydrochloric acid ---> barium chloride + water+ carbon dioxide

Answer 1

a.(Unionized) NaI + AgNO3 ===> AgI(s) + NaNO3

(Total ionic) Na+ + I- + Ag+ + NO3- ===> AgI(s) + Na+(aq) + NO3-(a)

(Total ionic) Ag+ + I- ===> AgI(s)

The rest of them you know how to do by yourself.

Answer 2

NaI + AgNO3 >> AgI + NaNO3

Na+ + I- + Ag+ + NO3- >> AgI + Na+ + NO3-

Ag+ + I- >> AgI (s)

Na2SO4 + BaCl2 >> BaSO4 + 2 NaCl

2 Na+ + SO42- + Ba2+ + 2 Cl- >> BaSO4 + 2 Na+ + 2 Cl-

Ba2+ + SO42- >> BaSO4 (s)

BaCO3 + 2 HCl >> H2O + CO2 + BaCl2

Ba2+ + CO32- + 2H+ + 2Cl- >> H2O + CO2 + Ba2+ + 2 Cl-

CO32- + 2H+ >> CO2 (g) + H2O (l)
