Answer:
HF is the Arrhenius acid and KOH is the Arrhenius base.
Explanation:
An Arrhenius acid dissociates in water to form H+ ions in solution.
An Arrhenius base dissociates in water to form OH- ions in solution.
Write the equations by breaking the compounds into their elements
HF→ H⁺ + F⁻ HF produces H⁺ when added to water, so it is the acid.
KOH→ K⁺ + OH⁻ KOH produces OH⁻ when added to water, so it is the base.
Sodium - metallic bonding

Chlorine - covalent bonding
Potassium oxide - ionic bonding
Answer:
A, because as metal warms, it expands, and makes it easier to remove
