Match each word to it's correct meaning. 1. chain reaction 2. critical mass 3. fission 4. fusion a spontaneous or induced reaction that continues to feed itself and keep itself going. nuclear reaction producing lighter elements and energy by splitting. mass of a nuclear substance that, if combined into one piece, would result in a spontaneous nuclear reaction. nuclear reaction producing heavier elements and energy by synthesis.

In an exothermic reaction the bonding energy of the product is: less than the reactants same as the reactants greater than the reactants dependent upon the presence of a catalyst

What is the mass of 0.46 mil of mgcl2

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.
