Question

Hello Yahoo Answers,
I am having trouble with this Chemistry Question. Can I please have help?


N^2 + 3H^2 = 2NH^3 ALL substances are gaseous

Atomic weights N = 14, H = 1.0
a. How many moles of hydrogen gas would be required to react with 0.5 moles of nitrogen gas?

b. If 1.5 moles of nitrogen gas reacts with excess hydrogen calculate the mass of ammonia ( NH^3) produced.

c. If all gases were measured at the same temperature and pressure what would be the ratio of reacting volumes for
Nitrogen : Hydrogen : Ammonia
_______:_________:________





Any Contribution wil be apprciated.

Thankyou

Answer 1

0.5molN2 x 3molH2/1molN2 = 1.5 moles H2

1.5molN2 x 2molNH3/1molN2 = 3 moles NH3

1 : 3 : 2
