1) If 26.2 L of o, are measured at 40.0°C, what would the volume be at standard temperature, assuming constant pressure?
Relationship:

Solubility would be your answer.

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.

D. h2o + h2o > h3o + oh- confirmed.
