give the structure of the organic product expected when ch2i2ch2i2 reacts with each of the alkenes in the presence of a zn–cuzn–cu couple:

You have 125g of a certain seasoning and are told that it contains 76.0 g of salt what is the percentage of salt by mass in this seasoning

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

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.
