How many moles of Zn will be needed to completely reach with 0.4 moles of HCI?

Which is a characteristic of mixtures?

Drive down any three characteristic of modern periodic table

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.
