Calculate the change in ph when 8.00 ml of 0.100 m hcl (aq) is added to 100.0 ml of a buffer solution that is 0.100 m in nh3 (aq) and 0.100 m in nh4cl (aq). refer to a list of ionization constants. calculate the change in ph when 8.00 ml of 0.100 m naoh(aq) is added to the original buffer solution.

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.
