Write the net ionic equation (including phases) that corresponds to Fe(ClO4)2(aq)+Na2S(aq)=FeS(s)+2NaClO4(aq)

Answer 1

You have the molecular equation.
Step 1. Convert to the ionic equation with these rules.

a. ppts are written as molecules.
b. gases are as molecules.
c. weak electrolytes (weak acids, weak bases, water, etc) are written as molecules.
d. everything else is written as ions (example: all of the aqueous solution are written as ions.

Step 2. Look at both sides of the equation and cancel ions that appear on both sides. What is left is the net ionic equation.
