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.

The answer is  a: x-rays—2 and ultraviolet rays—3.  hope i !

This kind of reaction is called a synthesis otherwise known as combination reaction
