$A$ gas is evolved when ethanol reacts with sodium. Name the gas evolved and also write the balanced chemical equation of the reaction involved.

(N/A) When ethanol $(CH_{3}CH_{2}OH)$ reacts with sodium metal $(Na)$,it forms sodium ethoxide $(CH_{3}CH_{2}ONa)$ and releases hydrogen gas $(H_{2})$.
The balanced chemical equation for this reaction is:
$2CH_{3}CH_{2}OH + 2Na \rightarrow 2CH_{3}CH_{2}ONa + H_{2}$
