net ionic equation

Question

Write a net ionic equation for the reaction that occurs when excess hydroiodic acid and manganese(II) sulfide are combined.

Answer 1

2HI(aq) + MnS(s) ==> H₂S + MnI₂ ... complete equation

2H⁺(aq) + 2I^-(aq) + MnS(s) ==> 2H⁺(aq) + S^2-(aq) + Mn²⁺(aq) + 2I^-(aq) ... complete ionic

MnS(s) ==> Mn²⁺(aq) + S^2-(aq) ... net ionic
