Natalia began to draw a diagram to compare bases and acids. two overlapping circles with the word bases above the left circle and acids above the right circle. there is an x in the left circle in the portion, which is not part of the overlap. which label should be written in the area marked x? conducts electric current produces oh– ions tastes sour reacts with carbonates

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.
