Acompound is found to contain 6.1% hydrogen and 93.9% oxygen. find it’s empirical formula.

Define dew point. i am writing this part to be able to ask the question

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.
