Zinc metal reacts with hydrochloric acid HCl to produce zinc (II) chloride ZnCl2 and hydrogen gas H2. How many molecules are in 15 g H2? (4.5x10^24 molec H2) Please help will mark brainliest!!

"electrical energy" transforms to "thermal energy".hope my answer has you : )

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.
