As energy is released during the formation of a
bond, the stability of the chemical system
generally
1) decreases
2) increases
3) remains the same

The answer is c. 320 g

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.
