| **What is the volume of hydrogen released by the interaction of 0.1 mol of ethanol with an excess of sodium. What kind of hydrogen is released?**

Given:

n (C2H5OH) = 0.1 mol

Find:

V (H2) -?

1) Write the equation of a chemical reaction:

2C2H5OH + 2Na => C2H5ONa + H2 ↑;

2) Determine the amount of substance H2 (taking into account the coefficients in the reaction equation):

n (H2) = n (C2H5OH) / 2 = 0.1 / 2 = 0.05 mol;

3) Calculate the volume of H2 (under normal conditions):

V (H2) = n (H2) * Vm = 0.05 * 22.4 = 1.12 liters.

Answer: The volume of H2 is 1.12 liters.
