Sorry i dont understand the question can you rephase it?

C. definite shape, definite volume. that is a solid.

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.

2licl + 3o2 i yook the test and it was correct.
