Rearrange the following equation to isolate partial pressure of H2 (PH2). Pbar = PHz + Ph20 + 13.6 Here PH20 is the partial pressure of water and Pbar is the barometer reading, and h is the height of the column.

Does heating a solution cause a dissolved gas to be more or less soluble? Gas + solvent ⇆ saturated solution (△Hsoln < 0) The reaction is almost always exothermic when a gas dissolves in a liquid. Increasing the temperature shifts the equilibrium to the left. (A) more (B) less
