(D) the substance can be stretched easily into wires

Its's science BTW

The correct answer is c b c a d

They are all full and don't need any more electrons in there outer shell.

Ithink that the answer is b

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.
