Question

!!!PLEASE HELP ASAP!!!!consider this reaction:

n2+3h2 -> 2nh3

suppose you have 3.0 L of nitrogen. how many liters of hydrogen do you need for a complete reaction? (One mole of any gas occupies 22.4 L under certain conditions of temperature and pressure. Assume those conditions for this question.)

A. 2.6L
B. 6.0L
C. 9.0L
D. 10.0L

Answer 1

9L!!! You take the moles of N2 in the reaction and then divide by one mole of nitrogen. Then you multiply that by the number of hydrogen moles in the reaction which in this case is 3. This gives you an answer of 3. You then take the number of hydrogen moles and multiply it by the 3L giving you 9L of hydrogen.
