Question

CH3-CH2-COOH+CaCO2-->

Answer 1

2CH3-CH2-COOH+CaCO3 ⇒(CH3-CH2-COO)2Са + H2О+ CO2↑

Answer 2

It seems there is a mistake in the chemical equation you provided. It appears to be a combination of two compounds, CH3-CH2-COOH (which is propanoic acid) and CaCO2 (which is not a recognized compound). Calcium carbonate is represented as CaCO3, not CaCO2.

If you meant to balance the equation with propanoic acid (CH3-CH2-COOH) and calcium carbonate (CaCO3), the balanced equation would be:

CH3-CH2-COOH + CaCO3 → Ca(CH3-CH2-COO)2 + CO2 + H2O

The balanced equation indicates that propanoic acid (CH3-CH2-COOH) reacts with calcium carbonate (CaCO3) to form calcium propanoate (Ca(CH3-CH2-COO)2), carbon dioxide (CO2), and water (H2O).
