Question 2 (1 point) Which of the following pairs of samples would have different half-lives? a Sample A: Radon-214 at 100 degrees Celsius Sample B: Radon-214 at 500 degrees Celsius b Sample A: Carbon-14 being held still Sample B: Caron-14 being shaken vigorously c Sample A: Uranium-235 in a nuclear reactor Sample B: Uranium-238 in a nuclear reactor d Sample A: Potassium-40 found in a banana Sample B: Potassium-40 found in a metal deposit

Yes it would be a physical change.

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.

We can't until we know what we are working with or on
