Ammonia is manufactured for fertilizer. The truck hauling the ammonia can hold 450 kiloliters of the gas, which
is 20 moles. If a buyer only needs to purchase 225 kiloliters of the gas, how many moles is the buyer receiving?

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?

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.

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
