State the number of hydrogens bonded to each labeled carbon in the following substance and give its molecular formula. (The molecular formula answer is case-sensitive. The order of atoms should be carbon, then hydrogen, then others in alphabetical order.)

Hope this will surely help you

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.
