How much hydrogen will be required to react with 1.12 liters of nitrogen to form ammonia NH3?

Given:
V (N2) = 1.12 L

To find:
V (H2) -?

1) Write the equation of a chemical reaction:
3H2 + N2 => 2NH3;
2) Determine the volume of H2 (under normal conditions), guided by the Gay-Lussac law (the law of volumetric ratios, taking into account the coefficients in the reaction equation):
V (H2) = V (N2) * 3 = 1.12 * 3 = 3.36 liters.

Answer: The volume of H2 is 3.36 liters.
