Question

Determine net ionic equations, if any, occuring when aqueous solutions of the following reactants are mixed. Select "True" or "False" to indicate whether or not the stated reaction (or "no reaction") correctly corresponds to the expected observation in each case. Calcium acetate and sodium carbonate; Ca2+(aq) + 2C2H3O2-(aq) --> Ca(C2H3O2)2(s) Ammonium sulfate and barium nitrate; No reaction occurs. Sodium phosphate and potassium nitrate; 2Na+(aq) + NO32-(aq) --> Na2NO3(s) Copper(II) sulfate and ammonium carbonate; No reaction occurs. Magnesium chloride and sodium hydroxide; No reaction occurs.
