Answer:

(NH₄)₂CO₃ (aq) + MgSO₄(aq)  →  (NH₄)₂SO₄(aq) + MgCO₃ (s) ↓  

Explanation:

We determine the reactants:

(NH₄)₂CO₃ → Ammonium carbonate

MgSO₄ → Magnesium sulfate

We determine the products:

(NH₄)₂SO₄ ; MgCO₃

All the salts from carbonates are precipitates:

(NH₄)₂CO₃ (aq) + MgSO₄(aq)  →  (NH₄)₂SO₄(aq) + MgCO₃ (s) ↓  

Ratio is all 1:1. 1 mol of ammonium carbonate reacts to 1 mol of magnessium sulfate in order to produce 1 mol of ammonium sulfate and 1 mol of magnessium carbonate.
