Predict the products in the reaction between magnesium and hydrochloric acid. if you were conducting this reaction in the lab, what would be your clue that this was a chemical reaction? if silver replaced magnesium as one of the reactants, what would you expect to happen?

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.
