1.What mass of aluminum is needed to react with 10.0 kg of chromium (III) oxide to produce chromium metal ? The chemical equation for the reaction is Al(l) + Cr2O3(s) →Al2O3(s) + Cr(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.
