Compared to nonmetals, metals tend to have- A. higher ionization energy
B. an acidic form of oxide
C. lower electronegativity
D. higher electron shielding

There are no metaphors.

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

I’m really not sure what’s the answer. sorry
