Question

$23$ g of sodium will react with ethyl alcohol to give:

• A. $1$ mol of $H_2$
• B. $\frac{1}{2}$ mol of $H_2$
• C. $1$ mol of $O_2$
• D. $1$ mol of $NaOH$

Answer 1

The correct option is B $\frac{1}{2}$ mol of $H_2$

The balanced chemical equation is as follows:

$C_2{H}_{5}OH+Na\to C_2{H}_{5}ONa+\frac{1}{2}{H}_2$

$1$ mol ($23$ g) of sodium reacts with $1$ mol of ethanol to produce $0.5$ mol of hydrogen.
