For the reaction, calculate how many grams of the product form when 1.8 g of cao completely reacts. assume that there is more than enough of the other reactant. cao(s)+co2(g)→caco3(s)

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.

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.
