Sagot :
When an aqueous solution of calcium chloride is mixed with an aqueous solution of sodium carbonate, the balanced reaction is CaCl₂ (aq) + Na₂CO₃ (aq) ⇒ 2NaCl (aq) + CaCO₃ (s).
The given reaction is a double-replacement reaction, in which there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product
Write down the reactants.
CaCl₂ (aq) + Na₂CO₃ (aq)
Separate the ions of each reactant.
CaCl₂ (aq) + Na₂CO₃ (aq) ⇒ (Ca²⁺)(2Cl⁻¹) + (2Na⁻)(CO₃⁻²)
Exchange the ions.
CaCl₂ (aq) + Na₂CO₃ (aq) ⇒ (2Na⁻)(2Cl⁻) + (Ca²⁺)(CO₃⁻²)
Hence, the balanced reaction is:
CaCl₂ (aq) + Na₂CO₃ (aq) ⇒ 2NaCl (aq) + CaCO₃ (s)
