Balance the redox reaction between oxalate and permanganate in acidic solution that will be used as the basis of titrations in this experiment. Fill in each blank with the appropriate stoichiometric coefficient as a numeral (avoid leading and lagging spaces). The coefficient on permanganate has been provided. C2O4^2-(aq) + Mn2O^- (aq) + H3O+(aq) → Mn^2+ CO2(g) H2O(l)

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.
