Answer

Explanation:

Step1: Observe Solute D's trend

By looking at the graph, as the temperature - axis moves to the right (increase in temperature), the solubility curve of Solute D goes down. So the solubility of Solute D decreases as temperature increases.

Step2: Compare slopes of curves

The slope of the solubility - temperature curve represents the rate of change of solubility with temperature. Solute A has the steepest positive - sloped curve, so the solubility of Solute A increases the most as temperature increases.

Step3: Find intersection point of C and D

Locate the intersection point of the curves of Solute C and Solute D on the graph. The x - value (temperature) at this intersection is 20°C.

Step4: Calculate solubility change for each solute

For Solute B: At 0°C, solubility is about 40 g/100g water, at 100°C, solubility is about 40 g/100g water, change is approximately 0 g. For Solute C: At 0°C, solubility is about 5 g/100g water, at 100°C, solubility is about 35 g/100g water, change is 30 g. For Solute D: At 0°C, solubility is about 20 g/100g water, at 100°C, solubility is about 15 g/100g water, change is about - 5 g. For Solute E: At 0°C, solubility is about 10 g/100g water, at 100°C, solubility is about 85 g/100g water, change is 75 g. For Solute A: At 0°C, solubility is about 10 g/100g water, at 100°C, solubility is about 85 g/100g water, change is 75 g. The solution whose solubility only changes by about 5 grams is Solute D.
