A sample of SO3 is introduced into an evacuated sealed container and heated to 600 K. The following equilibrium is established:
2SO3(g)?2SO2(g)+O2(g).
The total pressure in the system is found to be 3.0 atm and the mole fraction of O2 is 0.12.
Find Kp.

3. how much energy in joules is required to evaporate .0005 kg of liquid ammonia to vapor at the same temperature? 4. how much energy ( in megajoules ) is given up by .75 kg of water at 0c when it freezes to form ice at 0c? 5. explain how heat works between and at critical temperatures?

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.
