Cr(NO3)2 and CuSO4 are dissolved in water where the compounds react. In the reaction, copper metal is formed and each chromium ion loses one electron. What is the number of electrons transferred in the balanced reaction with the smallest whole-number coefficients

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.
