Zinc metal reacts with hydrochloric (hydrochloric) acid to release hydrogen gas and form zinc chloride. The reaction is described by the following equation:
Zn + 2HCl = ZnCl2 + H2;
1 mole of metal reacts with 2 moles of acid. This synthesizes 1 mol of salt and 1 mol of hydrogen.
N Zn = 130/65 = 2 mol;
The same amount of hydrogen will be synthesized. Let’s calculate its volume.
To do this, we divide its volume by the volume of 1 mole of ideal gas, which is 22.4 liters.
N H2 = 2 mol;
V H2 = 2 x 22.4 = 44.8 liters;
