Calcium fluoride (CaF2) is a slightly soluble salt, which dissociates in water according to the following reaction:

CaF2(s) ⇌ Ca2+(aq) + 2F–(aq)

What is the solubility product constant for this reaction?

Ksp = [Ca2+][F–]2
Ksp = [Ca2+][F–]
Ksp = [Ca2+]2[F–]
Ksp = 2[Ca2+][F–]

What effect does nuclear radiation have on atoms?

Iam in desperate need of with this !

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.
