During a laboratory experiment, 44.18 grams of Al2O3 was formed when O2 reacted with aluminum metal at 290.0 K and 1.3 atm. What was the volume of O2 used during the experiment? 3O2 + 4Al → 2Al2O3 A. 10.10 liters
B. 11.90 liters
C. 12.51 liters
D. 15.55 liters

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.
