The word equation for the reaction between a carbonate and an acid is:

Carbonate + Acid → Salt + Water + Carbon Dioxide

Here's a breakdown:

* Carbonate: A compound containing the carbonate ion (CO₃²⁻)

* Acid: A compound that donates hydrogen ions (H⁺)

* Salt: An ionic compound formed from the reaction of an acid and a base

* Water: H₂O

* Carbon Dioxide: CO₂

Example:

Sodium carbonate (Na₂CO₃) + Hydrochloric acid (HCl) → Sodium chloride (NaCl) + Water (H₂O) + Carbon dioxide (CO₂)
