In Experiment 1, about how many milliliters of water were added to the HCl solution to improve visibility of the end point

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.

What is the number of neutrons in an atom with atomic mass of 35

Which of the following is described by the equation h2o(s)+ heat=h2o(i) a freezing melting condensing evaporating
