Beаker X аnd Beаker Y each cоntain 1.0 L оf sоlution, as shown. A student combines the solutions by pouring them into a larger, previously empty Beaker Z and observes the formation of a white precipitate. Assuming that volumes are additive, which of the following sets of solutions could be represented by the diagram above? A diagram shows the combining of two solutions collected in two 1 liter beakers. The beaker X contains A g N O 3, (aqueous). The vessel has A g plus and N O 3 minus ions. Plus. The beaker Y contains M g C l 2 (aqueous). The vessel has M g minus and C l 2 plus ions. The resultant combination of the solutions is collected in a bigger beaker Z. The beaker is titled, A g C l (solid), and M g begin parenthesis N O 3 end parenthesis subscript 2, (aqueous). Precipitate in the beaker is labeled, Solid A g C l.
