Which answer below correctly identifies the changes you observed and the explanation when a candle
burns?
physical change because the wax melted and changed shape
chemical change because light and heat were formed as the wick and the wax burned
both physical change because the wax melted and changed shape and chemical change
because light and heat were formed as the candle burned
neither a physical change nor a chemical change because the wax only melted and light was
produced from the match

Yummy, tasty, delicious

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.
