A mixture of N2(g) and H2(g) reacts in a closed container to form ammonia, NH3(g). The reaction
ceases before either reactant has been totally
consumed. At this stage 1.8 mol N2, 1.8 mol H2,
and 1.8 mol NH3 are present.
How many miles of N2 and H2 were present originally.

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.
