Given the balanced equation representing a reaction: 4al(s) 3o2(g) → 2al2o3(s) as the aluminum loses 12 moles of electrons, the oxygen (1) gains 4 moles of electrons (2) gains 12 moles of electrons (3) loses 4 moles of electrons (4) loses 12 moles of electrons

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.
