Answer:
[tex]2 H^+ (aq) + CO_3^{2-} (aq)\rightarrow H_2O (l) + CO_2 (g)[/tex]
Explanation:
To begin with, let's write a reaction in a molecular form. Lithium carbonate reacts with hydrochloric acid according to the double displacement rules. Ltihium chloride is produced along with water and carbon dioxide:
[tex]Li_2CO_3 (aq) + 2 HCl (aq)\rightarrow 2 LiCl (aq) + CO_2 (g) + H_2O (l)[/tex]
To write a complete ionic equation, dissociate each aqueous species into ions:
[tex]2 Li^+ (aq) + CO_3^{2-} (aq) + 2 H^+ (aq) + 2 Cl^- (aq)\rightarrow 2 Li^+ (aq) + 2 Cl^- (aq) + CO_2 (g) + H_2O (l)[/tex]
Now cancel the ions spectators out, those are the repeating species on both sides of the equation:
[tex]2 H^+ (aq) + CO_3^{2-} (aq)\rightarrow H_2O (l) + CO_2 (g)[/tex]
