Answer 1

Answer on Question #42247 - Chemistry - Other

Question:

Using the equation $N_{2} + 3H_{2} \rightarrow 2NH_{3}$, determine how many moles of ammonia are produced when 30 moles of hydrogen are consumed.

Answer:

As is clear from the equation (the stoichiometric coefficients), when 3 moles of hydrogen are consumed 2 moles of ammonia are produced. So, we can write the proportion

3 moles $(H_2)$ – 2 moles $(NH_3)$

30 moles $(H_2)$ – X moles $(NH_3)$,

whence

$$X = 30 \cdot 2/3 = 20 \text{ moles}$$
