Which explains why mixtures can be separated? The components have different properties. The components have the same properties. The components are always made of small particles. The components are always made of large particles.

Chemical kinetics what was the rate of reaction in trial 3? choose the closest answer.

What are the similarities of physical and chemical change ?

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.
