Answer:

A radionuclide is an atom that has excess nuclear energy, making it unstable. This excess energy can be used in one of three ways: emitted from the nucleus as gamma radiation; transferred to one of its electrons to release it as a conversion electron; or used to create and emit a new particle from the nucleus. Wikipedia

Katen [24]

Answer:

Final volume = 0.103M x446ml/0.184m = 250ml

Explanation:

As time passes, the volume of solutions in the second beaker decreases and that in the first beaker increases. If we wait long enough, the final volumes and concentration in the beakers would be,

First beaker

Final concentration = 0.184M

Final volume = 0.296M x 284ml/0.184 = 457ml

Second beaker

Final concentration = 0.184M

Final volume = 0.103M x446ml/0.184m = 250ml
