Solutions of lithium carbonate and magnesium chloride are combined.

Question

a) Identify any precipitate(s) that will form.

b) Write the balanced molecular equation, including the state of each substance.

c) Write the ionic equation, including the state of each substance.

d) Identify all spectator ions.

e) Write the net ionic equation.

Answer 1

a) Identify any precipitate(s) that will form. MgCO₃ (magnesium carbonate)

b) Write the balanced molecular equation, including the state of each substance.

Li₂CO₃(aq) + MgCl₂(aq) ==> 2LiCl(aq) + MgCO₃(s)

c) Write the ionic equation, including the state of each substance.

2Li⁺(aq) + CO₃^2-(aq) + Mg²⁺(aq) + 2Cl^-(aq) => 2Li⁺(aq) + 2Cl^-(aq) + MgCO₃(s)

d) Identify all spectator ions. Li⁺ and Cl^- are spectator ions

e) Write the net ionic equation.

Mg²⁺(aq) + CO₃^2-(aq) ==> MgCO₃(s)
