Answer

a. No precipitate forms b. $Al(OH)_3$ c. $CaSO_4$ d. $NiS$

Work Step by Step

a. $$FeSO_{4(aq)}+2KCl_{(aq)} \Rightarrow FeCl_{2(aq)}+K_2SO_{4(aq)}$$ b. $$2Al(NO_3)_{3(aq)}+3Ba(OH)_2\Rightarrow 2Al(OH)_{3(s)}+3Ba(NO_3)_{2(aq)}$$ c. $$CaCl_{2(aq)}+Na_2SO_{4(aq)}=CaSO_{4(s)}+2NaCl_{(aq)}$$ d. $$K_2S_{(aq)}+Ni(NO_3)_{2(aq)} \Rightarrow NiS_{(s)}+2KNO_{3(aq)}$$
