A sample of 211 g of iron (III) bromide is reacted with
186 g of sodium sulfide to produce iron (III) sulfide
and sodium bromide. Using the balanced equation
below, predict which is the limiting reactant and the
maximum amount in moles of sodium bromide that
can be produced.
2FeBr3 + 3Na2S → Fe2S3 + 6NaBr

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

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.
