7 The nebular theory is the most widely accepted theory about the formation of the solar system. Which statement about the formation of the solar system below is NOT supported by the nebular theory? 1. The force of gravity pulled the particles in the nebula towards one another, forming rotating disk. 2. As the nebular particles moved closer together, intense pressure blew them apart. 3. When the particles were in close range, intense pressure caused them to stick together 4. The sun's great mass formed from the matter that was at the center of the disk.

The answer for this question is d. none of these

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.
