AP Chemistry Warm-up #2

Gaseous ammonia is synthesized from nitrogen and hydrogen.

1) Write a balanced chemical reaction:

2) If you take 355 L of hydrogen gas at 25.0 Celsius and 542 mm Hg and
    combine it with excess nitrogen gas, what is the theoretical yield of
    ammonia?

3) If the ammonia occupies a 125 L tank at 25.0 Celsius, what is its
     pressure?
            P_NH3 = nRT/V

                        = (6.900 moles x 0.08206 Latm/Kmole x 298.2 K ) / 125 L

                        = 1.35 atm
