A 0.7221-g sample of a new compound has been an- alyzed and found to contain the following masses of
elements: carbon, 0.2990 g; hydrogen, 0.05849 g;
nitrogen, 0.2318 g; oxygen, 0.1328 g. Calculate the
empirical formula of the compound.

Ithink the answer is pollution in the air steel made of iron and carbon

Olá. porque a reação na temperatura é muito rapida a do copo : )

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.
