How is the solubility of carbon dioxide gas in water increased?

by stirring the mixture

by increasing the pressure

by using more solvent

by increasing the temperature

It has to be b i hope this

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.
