Ompound a (c6h6) undergoes catalytic hydrogenation over lindlar catalyst to give a compound b which in turn undergoes ozonolysis followed by workup with aqueous h2o2 to yield succinic acid and two equivalents of formic acid. in the absence of a catalyst poison hydrogenation of a gives hexane. propose a structure for compound a.

This question is about electrolysis. metal spoons can be coated with silver. this is called electroplating. suggest one reason why spoons are electroplated?

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.
