Determine whether each substance listed is a strong acid, weak acid, strong base, weak base, acid salt, basic salt, or neutral salt. a) sodium hydroxide, NaOH b) ammonium chloride, NH4Cl c) perchloric acid, HClO4 g

a) Strong Base

b) Acid Salt

c) Strong Acid

Explanation:

As is the case with most hydroxides, NaOH is a strong base. It dissociates completely into Na⁺ and OH⁻ species when in water.

NH₄Cl is a acid salt, as it produces H⁺ species when dissolved in water:

HClO₄ is a strong acid, as it completely dissociates into H⁺ and ClO₄⁻ species when in water.

let that person have a turn to speak : )

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.
