net ionic equation

Question

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

Answer 1

2HI(aq) + MgCO3(aq) ==> H2O(l) + CO2(g) + MgI2(s) ... molecular equation

2H⁺(aq) + 2I^-(aq) + Mg²⁺(aq) + CO₃^2-(aq) ==> H₂O(l) + CO₂(g) + MgI₂(s) ... net ionic equation
