Complete the following chemical equations :
(i) `CH_(3)COOC_(2)H_(5)+NaOH rarr`
(ii) `CH_(3)COOH+NaOH rarr`
(iii) `C_(2)H_(5)OH+CH_(3)COOH overset("Conc. "H_(2)SO_(4))(rarr)`

Explanation

Let's complete the given chemical equations step by step.

### (i) `CH₃COOC₂H₅ + NaOH → ?`

1. **Identify the reactants**: The reactant `CH₃COOC₂H₅` is an ester (ethyl acetate), and `NaOH` is a strong base.
2. **Recognize the type of reaction**: This is a saponification reaction, where the ester reacts with a base to form a carboxylate salt and an alcohol.
3. **Write the products**: The products will be sodium acetate (the sodium salt of acetic acid) and ethanol.
4. **Complete the equation**:
