What is produced when ethanol reacts with sodium metal?

$A$ salt $X$ is formed and a gas is evolved when ethanoic acid reacts with sodium hydrogencarbonate. Name the salt $X$ and the gas evolved. Describe an activity and draw the diagram of the apparatus to prove that the evolved gas is the one which you have named. Also,write the chemical equation of the reaction involved.

Write true or false for the following statement:
Like mineral acids,ethanoic acid reacts with a base such as sodium hydroxide to give salt (sodium ethanoate or sodium acetate) and water.
