How many moles of H2 are needed to produce 18 moles of NH3 in the reaction below?
N2 + 3 H2 —> 2 NH 3

The answer to your question is 27 moles

Explanation:

Data

moles of H₂ = ?

moles of NH₃ = 18

balanced chemical reaction

                N₂  +  3H₂   ⇒   2NH₃

Process

To solve this problem use proportions and cross multiplication. Use the coefficients of the balanced reaction.

                3 moles of hydrogen 2 moles of ammonia

                x                                   18 moles of ammonia

                             x = (18 x 3) / 2

-Simplifying

                            x = 54/2

-Result

                             x = 27 moles                            

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

the maximum mass of nh3 is nh3 in grams
