Final answer:

Hydrobromic acid reacts with copper(II) carbonate to form copper(II) bromide, carbon dioxide, and water. The correct balanced chemical equation for this reaction is CuCO₃ (s) + 2HBr (aq) → CuBr₂ (aq) + CO₂ (g) + H₂O (l).

Step-by-step explanation:

The reaction between hydrobromic acid (HBr) and copper(II) carbonate (CuCO₃) is a double replacement reaction, where the hydrogen in the acid is replaced by copper, and the bromine combines with copper to form copper(II) bromide.

Additionally, carbon dioxide (CO₂) and water (H₂O) are formed because carbonic acid (H₂CO₃) that initially forms as a product breaks down readily into CO₂ and H₂O.

Therefore, the correct chemical equation for the reaction is:
CuCO₃ (s) + 2HBr (aq) → CuBr₂ (aq) + CO₂ (g) + H₂O (l).

This reaction is similar to the reactions provided in the reference:
H₂SO₄(aq) + CaCO₃(s) → CaSO₄(s) + CO₂(g) + H₂O(l)
and
2HCl(aq) + CaCO₃(s) → CaCl₂(aq) + CO₂(g) + H₂O(l).
