what is the pressure, in atmosphere, exerted by a 0.501 mol sample of nitrogen gas in a 10.0 L container at 298.0 K?​

Which statement is true about ionic compounds?

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.

Arrange the elements in order of increasing electronegativity. use the periodic table to you arrange the elements. p o k mg
