"Write the balanced chemical equation for the neutralization reaction that occurs when an aqueous solution of hydrochloric acid (HCl) is mixed with an aqueous solution of potassium hydroxide"

KOH(aq) + HCl(aq) ——-> KCl(aq) + H2O(l)

Explanation:

A neutralization reaction is the chemical reaction between an acid and an alkali to yield salt and water only.

In this particular question, the acid is hydrochloric acid while the alkali is potassium solution. We now write the equation of reaction as follows:

KOH(aq) + HCl(aq) ——-> KCl(aq) + H2O(l)

The salt formed here is KCl otherwise called potassium chloride

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
