The chemical reaction between the reagents luminol and bleach produces a brief flash of light. Which change would most likely make the light produced in the reaction last longer? increasing luminol concentration

adding a catalysts

decreasing the quantity of both reagents.

decreasing the temperature

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.
