1. If the pressure of CO2 inside a 1-liter bottle of seltzer (soda water) is 44 psi at 20°C, how much CO2 is dissolved in the seltzer?
k = 1.35 x 10-3 mol/L. atm
1psi = 0.068 atm

It conforms what ever surface its in.

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.
