38 g sodium nitrate is dissolved in water to make 538 g of solution. What is the percent
sodium nitrate in the solution?

What neutral atom is isoelectronic to mn+4

Why are the trends and exceptions to the trends in ionization energy observed?

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.
