Part 1: (a) Which of the following reactions will produce a precipitate? CuSO4(aq) + Fe(NO3)2(aq) → Kl(aq) + Zn(NO3)2(aq) - NaOH(aq) + MgCl2(aq) → NaOH(aq) + KNO3(aq) + Part 2 out of 2 (b) Write the net ionic equation for the precipitation reaction in Part A. Remember to include the proper physical states and charges of ions. When writing ions, if a charge number is not "l", place the charge number before the charge sign. If a charge number is...
