Answer

a. $Hg_2SO_4$ b. No precipitate c. $MgCO_3$ d. $Al_2(CrO_4)_3$

Work Step by Step

a. $$Hg_2(NO_3)_{2(aq)}+CuSO_{4(aq)}\Rightarrow Cu(NO_3)_{2(aq)}+Hg_2SO_{4(s)}$$ b. $$Ni(NO_3)_{2(aq)}+CaCl_{2(aq)}\Rightarrow Ca(NO_3)_{2(aq)}+NiCl_{2(aq)}$$ c. $$K_2CO_{3(aq)}+MgI_{2(aq)}\Rightarrow 2KI_{(aq)}+MgCO_{3(s)}$$ d. $$3Na_2CrO_{4(aq)}+2AlBr_{3(aq)}\Rightarrow 6NaBr_{(aq)}+Al_2(CrO_4)_{3(s)}$$
