Which of the following is the correct net ionic equation for the reaction between aqueous solutions of Na2S and Fe(ClO4)3?
a) Na2S + Fe(ClO4)3 → NaClO4 + FeS
b) Na+ + S2- + Fe3+ + 3ClO4- → Na+ + ClO4- + FeS
c) 2Na+ + S2- + 3Fe3+ + 3ClO4- → 2Na+ + 3ClO4- + Fe2(SO4)3
d) 2Na+ + S2- + 3Fe3+ + 3ClO4- → 2Na+ + 3ClO4- + Fe2(SO4)3 + 2FeS
