Determine the number of moles of O2(g) in the cylinder. The gram-formula 1 point
mass of O2(g) is 32.0 g/mol. (show your work) *
The diagram below represents a cylinder with a moveable piston containing 16,0 gofo, g).
At 298 K and 0.500 atm, the 0,(g) has a volume of 24.5 liters.
0 (9)
P=0.500 atm
V=24.5 L
T = 298 K
Your answer

maybe the spark is gone, love is a weird emotion and there is a possibility he may have found somebody else.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
