what statement describes the process of solar nuclear fusion?
hydrogen molecules are fused together and become oxygen molecules, giving off large amounts of energy.
helium molecules are fused together and become hydrogen molecules, giving off large amounts of energy.
hydrogen atoms are fused into deuterium, then helium-3, then helium-4, each step giving off large amounts of energy.
hydrogen atoms are fused into deuterium, then helium-4, then back into hydrogen, each step giving off large amounts of energy

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.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
