Write a balanced molecular, complete ionic and, where possible, net ionic equation for each
of the following reactions:
a. potassium hydroxide reacts with sulfuric acid to produce potassium sulfate and water.
b. lithium carbonate reacts with hydrochloric acid to produce lithium chloride, water and
carbon dioxide.
c. aluminum chloride reacts with iron (iii) nitrate to produce aluminum nitrate and iron(iii)
chloride.
d. potassium iodide reacts with ammonium nitrate to produce potassium nitrate and
ammonium iodide.

Ametal with a large number of free flowing electrons most likely has good conductivity

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.

Well you can immediately rule out a and d because if a metal were to lose or gain protons, then it would become a different element all together. the answer here is b because the positive symbol with a number refers to how many electrons the metal can give away to become stable.
