The reaction between sodium bicarbonate (NaHCO₃) and calcium chloride (CaCl₂) produces calcium carbonate (CaCO₃), sodium chloride (NaCl), carbon dioxide (CO₂) and water (H₂O).

Here's the balanced chemical equation:

2 NaHCO₃ (aq) + CaCl₂ (aq) → CaCO₃ (s) + 2 NaCl (aq) + H₂O (l) + CO₂ (g)

Explanation:

* Calcium carbonate (CaCO₃) is an insoluble white solid, which forms as a precipitate.

* Sodium chloride (NaCl) is soluble and remains in solution.

* Carbon dioxide (CO₂) gas is released, causing effervescence (bubbling).

* Water (H₂O) is also produced.

Key points:

* This is a double displacement reaction, where the cations and anions of the reactants switch places.

* The reaction is exothermic, meaning it releases heat.

* The formation of the insoluble calcium carbonate drives the reaction forward.
