HELP! True or false: When there are zero lone pairs on the central atom, the shape is
symmetrical (assuming all of the bonds are the same).

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.

Ithink a i think i tried i hope that : )

The answer is d for this question
