DDT is synthesized from the halogenation of the benzene ring through substitution of hydrogen atoms with
atoms.

Hey how did you manage to type such a big lab report

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.

Answerchemical energy;
