22 at 101.3 kpa and 298 k, a 1.0-mole sample of which compound absorbs the greatest amount of heat as the entire sample dissolves in water? (1) libr (3) naoh
(2) nacl (4) nh4cl

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.
