When 18.0 g H20 is mixed with 33.5 g Fe, which is the limiting reactant?

What are transitions between a liquid and gas called? identify which way they are transitioning

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.

Hey guys so i need to know what is _nh3+> nh4oh ~chemistry~
