Sergio [31]
Answer:

if you’re looking for a balanced equation it would be:

Methanol +ethanoic acid ==> methyl ethanoate + water ( in the presence of concentrated sulfuric acid )

CH3OH + CH3COOH==> CH3COOCH3 + H2O

But, if you were looking for what it would be called it would be:

ethanoic acid with methanol will produce methyl ethanoate.

~~~~~~

And the reaction between Methanol and Ethanoic acid is known as esterification.
