The balanced chemical equation for the reaction between calcium carbonate (CaCO₃) and hydrochloric acid (HCl) is:
A. CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂
B. CaCO₃ + HCl → CaCl₂ + H₂O + CO₂
C. CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O
D. CaCO₃ + HCl → CaCl₂ + CO₂ + H₂O
The balanced equation is CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O.
