Iron (fe) reacts with copper sulfate (cuso4) to form iron (ll) sulfate. in this reaction, cu2+ gains electrons to form cu. which statement is true about this reaction ? fe(s) + cuso4 (aq) > feso4(aq) + cu(s)

The formation of a solid, also known as a is an indication of a chemical change. precipitate particulate particle powder

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.

Suppose you discovered a new element with 120 protons and 2 electrons in its outer level . i'm what group does this new element belong? what properties would you expect it to have
