Use the gizmo to find the concentration of the mystery ch3cooh. use the titrant and indicator shown below perform the titration. what is the titrant volume? titrant analyte indicator titrant volume analyte concentration naoh ch3cooh phenophthalein select one: a. 20.0 ml b. 27.0 ml c. 30.0 ml d. 24.0 ml

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.

What is the mass of naoh that would have to be added to 500 ml of a solution of 0.20 m acetic acid in order to achieve a ph of 5.0?
