19 At 298 K and 1 atm Br2 is a liquid with a high vapor pressure and Cl is a gas Those observations provide evidence that under the given conditions the A Forces among Br2 molecules are stronger than those among Cl molecules B Forces among Cl molecules are stronger than the Cl Cl bond C Br Br bond is stronger than the Cl Cl bond D Cl Cl bond is stronger than the Br Br bond Ne HF C H6 CH4 20 Which of the substances listed above has the highest boiling point and why A Ne because its atoms have the largest radius B HF because its molecules form hydrogen bonds C C H6 because each molecule can form multiple hydrogen bonds D CH4 because its molecules have the greatest London dispersion forces 21 Write the net ionic equations for the following two aqueous reactions a Nitrous acid HNO2 reacts with potassium hydroxide b A precipitate forms when solutions of lead II nitrate and sodium iodide are mixed
