If 2.50 moles of Cl2 gas occupy 50.0 L, how many moles are
present in 80.0 L H2? Assume temperature and pressure
stayed constant

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.
