Solution

## The gas evolved when Ethanol reacted with Sodium:Ethanol is an Alcohol having a molecular formula, ${\mathrm{C}}_{2}{\mathrm{H}}_{5}\mathrm{OH}$.It basically reacts with Sodium metals to form sodium alkoxide and Hydrogen gas gets evolved during the process. The balanced chemical equation of the reaction:Ethanol reacts with Sodium metal to form Sodium ethoxide along with the evolution of hydrogen gas.The balanced chemical equation of the given reaction can be written as: $\underset{\left(\mathrm{Ethanol}\right)}{2{\mathrm{C}}_{2}{\mathrm{H}}_{5}\mathrm{OH}\left(\mathrm{aq}\right)}+\underset{\left(\mathrm{Sodium}\right)}{2\mathrm{Na}\left(\mathrm{s}\right)}\to \underset{\left(\mathrm{Sodium}\mathrm{ethoxide}\right)}{2{\mathrm{C}}_{2}{\mathrm{H}}_{5}\mathrm{ONa}\left(\mathrm{aq}\right)}+{\mathrm{H}}_{2}\left(\mathrm{g}\right)$Hence, the gas evolved when Ethanol reacted with Sodium is Hydrogen gas, for which the balanced reaction has been given above.
