How to solve this chemical equation.

Question

HCH3 COO (aq) + CaCO3 (s) → H2 CO3 (aq) + Ca(CH3 COO)2 (aq) H2 CO3 (aq) → H2 O (l) + CO2 (g)

Answer 1

If by solve this you mean to balance it, then you have the following:

2HCH₃COO (aq) + CaCO₃ (s) → H₂CO3 (aq) + Ca(CH₃COO)₂ (aq) → Ca(CH₃COO)₂ (aq) + H₂O (l) + CO₂ (g)

Once the H₂CO₃ is formed in the first reaction, it decomposes to H₂O + CO₂
