HELP ASAP Two balloons of the same volume are filled with helium. The kinetic energy of the helium molecules in Balloon 1 is higher than the kinetic energy of the helium molecules in Balloon 2. What can you conclude about these balloons? 
A. The temperature is lower in Balloon 2. 
B. Balloon 1 has more helium in it than balloon 2. 
C. The temperature is lower in the Balloon 1. 
D. The balloons have two different kinds of helium.

The correct answer is d

The answer is a) carbon-12

Rn in the right answer

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.
