Write the structures of products `(A)` and `(B)`
`CH_(3) -overset (O) overset(||) C-overset(18) OC_2 H_5 overset(H_(3) O^(+))rarr (A) + (B)`.

Explanation

To solve the problem, we need to analyze the hydrolysis of the given ester, which is ethyl ethanoate (also known as ethyl acetate) with the structural formula \( CH_3COOCH_2CH_3 \). The hydrolysis is performed in the presence of water (\( H_2O \)) and involves an acidic medium, which will lead to the formation of an acid and an alcohol.

### Step-by-step Solution:

1. **Identify the Ester**: The given ester is ethyl ethanoate, which can be represented as:
\[ CH_3COOCH_2CH_3 \]
