Does the equation describe a chemical change or a physical change? Explain your reasoning. C17H17ON3(s) + 2C4H6O3(l) - -> C21H21O5N(s) + 2C2H4O2(l)

Ibelieve its because the stove is a cleaner burning fuel

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.

It must be measured in k.hope my answer is to you : )

The answer will be +250
