Idont know what to do. barium sulfate, baso4, is made by the following reaction.
ba(no3)2(aq) + na2so4(aq)
baso4(s) + 2nano3(aq)
what is the theoretical yield of barium sulfate, expressed in grams, if 75.00 g of ba(no3)2 were used with an excess of na2so4?

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.
