Answer:
The molecular equation for the reaction of CaCO₃ with CH₃COOH is:
CaCO₃ (s) + 2CH₃COOH (aq) → Ca(CH₃COO)₂ (aq) + H₂O (l) + CO₂ (g)
Option 1
Explanation:
CaCO₃ + 2CH₃COOH → Ca(CH₃COO)₂ + H₂O + CO₂
Option 3 is the same equation as option 1, but calcium acetate, does not precipitate, so the formed salt, is not a solid.
Option 2 and 4 are wrong because calcium acetate molecular formula is
Ca(CH₃COO)₂
Ca(CH₃COO)₂ → Ca²⁺ + 2 CH₃COO⁻
