Answer 1

3a. Consider the reaction when aqueous solutions of chromium(II) nitrate and barium iodide are combined. The net ionic equation for this reaction is:

Cr(NO3)2(aq) + BaI2(aq) = CrI2(s) + Ba(NO3)2(aq)

net ionic includes only reacting species

Cr2+(aq) + 2I-(aq) = CrI2(s)

3b. Consider the reaction when aqueous solutions of zinc sulfate and iron(III) acetate are combined. The net ionic equation for this reaction is:

ZnSO4(aq) + Fe(CH3COO)3(aq) = No reaction

acetate and sulfate of these metals are soluble

3c. Consider the reaction when aqueous solutions of sodium nitrate and barium hydroxide are combined.

The net ionic equation for this reaction is:

NaNO3(aq) + Ba(OH)2(aq) = NO REACTION

nitrates are soluble Hydorxide of Barium are also soluble, expect no reaction

3d. Consider the reaction when aqueous solutions of sodium hydroxide and potassium acetate are combined.

The net ionic equation for this reaction is:

NaOH(aq) + KCH3COO(aq) = NR

there is NO REACTION, alkali metals will not form precipitates
