Calculate the pH of the solution prepared by adding 10.0 mL of 0.40 M NaOH(aq) to 50.0 mL of 0.20 M HBrO(aq). Ka for HBrO = 1.8×10−5. Temperature 25 deg C.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
