A sample of gas contains 0.1000 mol of N2(g) and 0.3000 mol of H2(g) and occupies a volume of 15.2 L. The following reaction takes place: N2(g) + 3 H2(g) → 2NH3(g)

Required:
Calculate the volume of the sample after the reaction takes place, assuming that the temperature and the pressure remain constant.

Apackage contains 1.33 lb of ground round. if there’s 29% fat, how many grams of fat are in the round? i got 175 g but the textbook says the answer is 91 g of fat. how?

Which statement is usually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.

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.
