Ascientist is trying to conduct an experiment that requires a strong electrolyte. he has four different compounds in solution, but he is not sure what they are. he runs some tests, and gathers some clues about the properties of each solution. which solution should he definitely not use to perform the experiment?

a. solution 1: conducts electricity well
b. solution 2: is not completely ionized
c. solution 3: is completely dissociated in solution
d. solution 4: is void of carbon or any molecular compounds; seems to be dissociated

Maybe you should get some from your teacher and learn more so you can get your grades up and maybe study a bit more

Ibelieve the answer 4 moles

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.

Density= mass/volume so 5.1 divided by 4.7 is  5.1 / 4.7 =1.08510638298round to the correct number of sig figs
