Need question 2-9
General Chemistry II Questions (summarize the question and then answer in your 1. What are two molecular-scale factors that influencet attraction like ion-ion or ion-dipole attractions? (hint Describe and draw a picture representing both pure NaN bonds/intermolecular forces must be broken for dissolution the strength of an electrostatic 2. NaNO,(s) and H:O(l). What your to occur? Label them on 3. Describe and draw a picture representing a solution forces must have been formed for this solution to have drawing Using the concepts of saturation (unsaturated, satura of NaNO (aq). What bonds/interm been made? Label them on your 4. a. What d b. c. oes any given point on either line represent on your What is represented by the points below the line? What is represented by the points above the line? 5. Which of the two salts in vestigated is more soluble in water over the temperature ran ata? Explain how you know using actual values from your plot. 6. From YOUR chart, what is the molality of a saturated solution of From YoUR chart, what is the pom of a saturated solution of KNOs atwith either unsaturates °C? 9. Use the chart below to answer the questions For a -d, answer with either unsatur below. Solubility Curves a. 50g NH Cl in 100g water at 50°c b. 25g NH Cl in 50g water at 60°C c. A saturated solution of KCI at 90°C which has 130 120 110 oh 100 been cooled to 65°C A saturated solution of HCI at 90°C which has been cooled to 65 C How many grams of KCIOs is needed to form a saturated solution in 50g water at 60 C? Will you need to warm or cool an unsaturated solution of HCI form a saturated solution?
