In the titration the student used 25.0 cm3 of sodium hydroxide. This volume reacted with exactly 20.0 cm3 of 0.1 mol/dm3 sulfuric acid solution.

The equation for the reaction is:

2NaOH + H2SO4 → Na2SO4 + 2H2O
What is the concentration in mol/dm3 of the sodium hydroxide solution?

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
