Ammonia is produced by the chemical reaction of hydrogen and nitrogen

N2 + 2H2 → 2NH3

How many moles of H2 are needed to react with 1.8 moles of N2

Respuesta :

Answer:

3.6 mol H₂

Explanation:

  • N₂ + 2H₂ → 2NH₃

In order to convert from N₂ moles to H₂ moles we need to use a conversion factor. This conversion factor has to have N₂ moles in the denominator and H₂ moles in the numerator, using the stoichiometric coefficients of the reaction, as follows:

  • 1.8 mol N₂ * [tex]\frac{2molH_2}{1molN_2}[/tex] = 3.6 mol H₂
