The reaction between methanol (CH3OH) and ethanoic acid (CH3COOH) is an esterification reaction. This reaction forms methyl ethanoate (CH3COOCH3), also known as methyl acetate, and water (H2O).

Here's the balanced chemical equation:

CH3OH + CH3COOH ⇌ CH3COOCH3 + H2O

Explanation:

* Methanol (CH3OH) acts as the alcohol.

* Ethanoic acid (CH3COOH) acts as the carboxylic acid.

* Methyl ethanoate (CH3COOCH3) is the ester formed.

* Water (H2O) is a byproduct of the reaction.

This reaction is reversible, meaning it can proceed in both directions. To favor the formation of the ester, the reaction is typically carried out in the presence of an acid catalyst, such as concentrated sulfuric acid, and heat.
