Correct the ones that are marked wrong:

Prelab for Table III: Write the 3 steps for the net ionic equation for the reactions listed below. First one is done for you. Assume all reactants are aqueous 0.1 M solutions except where other phases and concentrations are noted. The molarities that are shown are for experimental purposes and do not affect the net ionic equations. You will tear this out along with the other tables and place on the instructor's bench.

Expert Solution
Step 1

1 (b)                                                     BaSO4(s) + HCl (aq) -----------> No reaction

BaSO4 is insoluble solid. It is not soluble in HCl.  Hence, there is no possibility of reaction between BaSO4 and HCl.

2 (b)  NiCO3 reacts with HCl and liberates CO2.                                       

                                                               NiCO3 (s) + HCl → NiCl2 + H2O + CO2
