Complete the following precipitation reaction with balanced molecular, total ionic, and net ionic equations. Remember to include the proper physical states and charges of ions. When writing ions, if a charge number is not "1", place the charge number before the charge sign. If a charge numbers "1", do not include the charge number in the formula.
