uses a clean spatula to transfer about 0.3 g each of lithium dichromate and barium nitrate, respectively, into two separate test-tubes. Then adds about 4.0 mL of deionized water to dissolve each compound. The barium nitrate solution is colorless and transparent, but the lithium dichromate solution, although transparent, has a yellowish color. She cautiously swirls both test tubes to ensure complete dissolution and then pours the lithium dichromate solution into the test-tube containing the barium nitrate solution. Please help ASAP!...

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
