<p> 2nd Semester Review Worksheet</p><p>1. How is hydrogen bonding responsible for the high surface tension and low vapor pressure of water?</p><p>2. What is the difference between evaporation, condensation, and boiling?</p><p>3. Compare and contrast a solvent, solute and solution.</p><p>4. What is the process called when a solvent dissolves a solute?</p><p>5. What is an electrolyte? How does a strong electrolyte differ from a weak electrolyte? Give an example of an electrolyte and a non-electrolyte.</p><p>6. What is meant by “water of hydration”?</p><p>7. How does a solution form? Give details using current theories about the “motion” of molecules.</p><p>8. List the formula and unit to solve for each: a. Molarity</p><p> b. Molality</p><p> c. Percent by volume</p><p> d. Percent by mass 9. Calculate the molarity of each solution. a. 350 grams of Cu3(PO4)2 in 2.75L of solution</p><p> b. 1.25 mol of MnO2 in 750mL of solution</p><p>10. You have the following stock solutions available: 2.00M NaCl, 4.00M KNO3, and 0.50M MgSO4. Calculate the volumes you must dilute to make the following solutions. a. 500.0mL of 0.500M NaCl</p><p> b. 2.0L of 0.20M MgSO4</p><p> c. 50.0mL of 0.20M KNO3</p><p>11. What is the concentration, in percent (m/v), of a solution with 75.0g K2SO4 in 1500mL of solution?</p><p>12. How many kilograms of water must be added to 9.0g of oxalic acid (H2C2O4) to prepare a 0.025m (molality) solution?</p><p>13. Calculate the number of moles of solute present in 400mL of 0.240M MgBr2?</p><p>14. Look at the reaction below:</p><p>CaCl2(aq) + Na2SO4(aq)  CaSO4(s) + 2NaCl(aq)</p><p>If you begin 250.0mL of 1.50M CaCl2(aq) in excess Na2SO4 solution, how much solid CaSO4 will you form if all of the CaCl2(aq) reacts? Make sure you report the correct number of significant figures. Show all of your work.</p>
