2. When solutions containing 1.0000 g of BaClz and 1.0000 g of Na2SO, were mixed, solid BaSO, formed. The Baso precipitate was filtered out of the solution, allowed to dry, and then weighed. The mass of Baso, that was isolated from solution was 1.0400 g Use this information to answer the following questions. Pay close attention to the proper use and reporting of significant figures and units. You must show all of your work (i.e., your calculations) for full credit. (a) Write a balanced chemical equation that shows the reaction that occurs when an aqueous solution of BaClz reacts with an aqueous solution of Na2S0, to form aqueous sodium chloride and solid Basos. In your equation, you should indicate the physical states of each reactant and product. If you're unsure about this, please read section 8.1 of your textbook (c) How many moles of Na2sO4 are in 1.000 g of Na2S04? 3. When using a Bunsen burner, what are the characteristics of a "cool flame" vs. a "hot (b) How many moles of BaClz are in 1.000 g of BaCl2? Show your work to receive credit. flame"? What does each type of flame look like?
