Consider the following data on some weak acids and weak bases: acid name formula Ka hypochlorous acid HClO 3.0 x 10^-8 nitrous acid HNO3 4.5 x 10 ^-4Use this data to rank the following solutions in order of increasing pH. In other words, select a '' next to the solution that will have the lowest pH, a '' next to the solution that will have the next lowest pH, and so on. solution pH 0.1 M C6H5NH30.1 M NaNO2 0.1 M KClO 0.1 M KCl

What is the volume of 2.5 moles of nitrogen gas (n2)at standard temperature and pressure (stp)?

A0.10 m aqueous solution of sodium sulfate is a better conductor of electricity than a 0.10 m aqueous solution of sodium chloride. which of the following best explains this observation? (a) sodium sulfate is more soluble in water than sodium chloride. (b) sodium sulfate has a higher molar mass than sodium chloride. (c) to prepare a given volume of 0.10 m solution, the mass of sodium sulfate needed is more than twice the mass of sodium chloride needed. (d) more moles of ions are present in a given volume of 0.10 m sodium sulfate than in the same volume of 0.10 m sodium chloride. (e) the degree of dissociation of sodium sulfate in solution is significantly greater than that of sodium chloride.
