Would you agnee to buy 1 trillion (1,000,000,000,000) gold atoms for $5? explain why or why not. find the current price of the gold at http: // money. cnn. com/data/ commondities/(1 troy ounce=31.1 g)

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.

Sorry i dont understand the question can you rephase it?

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.
