Respuesta :

The coefficient next to the reactants represent the amount of moles of the reactant. We are looking for the mole ration of hydrogen and ammonia. The compound for Hydrogen is H2 and the compound for ammonia is NH3.

The answer is 3/2.

Answer:

3:2

Explanation:

N₂ + 3H₂ → 2NH₃

From the stoichiometry of the reaction, 3 moles of hydrogen is required to react with 1 moles of Nitrogen to give two moles of Ammonia (NH3).

The moles ratio of Hydrogen to Ammonia is 3:2.
