Please help!! What is the theoretical yield of hydrogen gas if 36.0 g of water undergoes electrolysis to produce molecular hydrogen and molecular oxygen and 38.0g of hydrogen is collected?

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.

Hey can you me with this i really need y’all
