Calculate the pH of a 0.346 M aqueous solution of hypochlorous acid (HClO, Ka = 3.5×10-8) and the equilibrium concentrations of the weak acid and its conjugate base.

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
