Write a complete ionic equation for the reaction (if any) that occurs when aqueous solutions of lithium sulfide and copper(II) nitrate are mixed.

2Li+(aq) + S2-(aq) + Cu2+(aq) + 2NO3-(aq) => CuS(s) + 2Li+(aq) + 2NO3-(aq)

Write the net ionic equation for the reaction that occurs when aqueous solutions of K2S and Fe(NO3)2 are mixed.

Fe2+(aq) + S2-(aq) → FeS(s)

Write an net ionic equation for the reaction that occurs when aqueous solutions of H2SO4 and KOH are mixed.

H+(aq) + OH-(aq) => H2O(l)

Write a net ionic equation for the reaction that occurs when aqueous solutions of Na2CO3 and HCl are mixed.

2H+(aq) + CO32-(aq) => H2O(l) + CO2(g)

Write a complete ionic equation for the reaction that occurs when aqueous solutions of MgSO3 and HI are mixed.

2H+(aq) + SO32-(aq) => H2O(l) + SO2(g)
