The specific heat of zinc is 0.39 j/g*��
c. how much energy needed to change the temperature of 34g of zinc from 22��c to 57��
c. is the energy absorbed or released?

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.
