You dissolved 3.00 g of calcium chloride and 3.50 g of sodium carbonate in tap water separately, mixed the two solutions together, and collected and dried the precipitate on a filter paper. The data for the precipitate is collected below: Mass of filter: 1.34 g Mass of filter paper & precipitate 3.87 g Determine the theoretical yield for the precipitate. ["3.30 g", "3.80 g", "2.51 g", "2.71 g"] Determine the percent yield. ["142%", "76.7%", "77.5%", "93.4%"] Tap water contains calcium ions and you used it to complete the experiment in the problem above. What would happen to the collected precipitate? ["Nothing would happen to the precipitate.", "I would collect the same amount of precipitate.", "I would collect less precipitate than I should.", "I would collect more precipitate than I should."]
