Write the net ionic equation. An aqueous solution of sodium carbonate is added to an aqueous solution of calcium chloride. Calcium carbonate is precipitated

Ca +  CO₃²⁻   → CaCO₃

Explanation:

Solution:

      Sodium carbonate  = Na₂CO₃

      Calcium chloride = CaCl₂

      Calcium carbonate is precipitated

Reaction equation:

           Na₂CO₃  +  CaCl₂  →  CaCO₃ + 2NaCl

The net ionic equation:

        2Na⁺ + CO₃²⁻   + Ca + 2Cl⁻  → CaCO₃ + 2Na⁺ + Cl⁻

the spectator ions which both appears on both sides will cancel out and leave behind the net ionic equation:

              Ca +  CO₃²⁻   → CaCO₃

c (diamond),

sio2 (quartz)

the answer is na (sodium)
