Two scientists wanted to test the solubility of different substances. Solubility is a measure of how many moles of a given substance (known as the solut e) can dissolve in a given volume of another substance (known as the solvent). The solvent can also be thought of as the substance present in greater amount, while the solute can be seen as the substance present in lesser amount. The scientists performed the following experiments to investigate this property.Experiment 1The scientists tested the number of moles of several substances that could be completely dissolved in 50mL of water at various temperatures. They made their solutions by slowly adding amounts of each substance to beakers sitting on a hot plate containing water and a stirring rod until no more of the substance dissolved in the solution. The beakers were weighed before and after the additions and the difference in mass was calculated to be the added mass of the substance. The researchers then calculated the number of moles that dissolved for each trial using the molecular mass and the recorded mass for each trial. Results are recorded in Table 1.Table 1Experiment 2In this experiment, the scientists wanted to test the solubility of NaCl in a variety of liquids at several temperatures. Their procedure was similar to that of Experiment 1, but with a range of liquids and only one solid. The results are compiled in Table 2.Table 2Q.Which of the following correctly ranks the solutes from Experiment 1 in decreasing order of solubility in water at 50C?

Directions:Read the passages and choose the best answer to each question.PassageA pluvial lake is an ancient lake with high water levels, generally associated with times of high precipitation. Lake Bonneville was a prehistoric pluvial lake that covered much of North America’s Great Basin region during the last ice age (see Figure 1). Most of the territory it covered was in present-day Utah, though parts of the lake extended into present-day Idaho and Nevada. Formed about 32,000 years ago, it existed until about 16,800 years ago, when most of the contents of the lake were released through the Red Rock Pass in Idaho.At more than 1,000 feet (305 m) deep and more than 19,691 square miles (50,999.5 km2 ) in area, Lake Bonneville was nearly as large as Lake Michigan and significantly deeper. Over time, increasing temperatures in North America caused the lake to begin drying up, leaving Great Salt Lake, Utah Lake, Sevier Lake, Rush Lake, and Little Salt Lake as remnants. While each of these lakes is considered a freshwater lake, the salinity levels are higher than normal. Figure 2 shows a cross-section of part of Utah Lake and its sediment and bedrock, with measurements taken at the cities of Genola and Provo and two test sites in between.Q.Great Salt Lake is fed mainly by 3 tributary rivers that deposit large amounts of minerals into its waters. The lake is salty because it has no outflow for water other than evaporation, which is predominately mineral-free.If local temperatures were to decrease significantly, while freshwater rain were to increase significantly, what would be the likely resulting change to the salinity of the Great Salt Lake?
