Explain why it was important to dissolve the antacid tablet first and then divide the solution into aliquots? what would have been a potential point of concern if you had divided the tablet into aliquots first and then dissolved them into equivalent volumes?

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.
