Calculate the ratio of h+ ions to ohβ ions at a ph = 7. find the concentration of h+ ions to ohβ ions listed in table b of your student guide. then divide the h+ concentration by the ohβ concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to ohβ ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of ohβ ions at a ph = 7? mol/l what is the ratio of h+ ions to ohβ ions at a ph = 7? : 1

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.
