Which of the following statements are correct? More than one answer is possible. (Select all that apply.) O LiF will have a higher vapor pressure at 25 °C than H2S. NH3 is more soluble in CCI4 than in water. O NH3 will have a higher vapor pressure at 25 °C than Beo. O As the polarity of a covalent compound increases, its solubility in water increases. U NH3 will have a lower vapor pressure at -50 °C than NO.
View Policies Show Attempt History Current Attempt in Progress X Incorrect. Ethanol, with AHvap = 40.5 kJ mol1, has a higher AHvap than methanol, which is 35.2 kJ mol1, due to its larger size and greater intermolecular forces. Because the AHvap for ethanol is larger, we would expect that for the two liquids to reach the same vapor pressure, the temperature for ethanol would have to be higher. If the vapor pressure is 0.0992 atm at 27.3 °C, what would the temperature be when the vapor pressure is 8.53 atm? The temperature will be i 140 К. eTextbook and Media Hint Assistance Used Save for Later Attempts: 7 of 15 used Submit Answer !
When copper metal is added to nitric acid, the following reaction takes place Cu (s) + 4 HNO₃ (aq) → Cu(NO₃)₂ (aq) + 2 H₂O (l) + 2 NO₂ (g) Calculate the volume of NO₂ gas collected over water at 25.0 °C when 2.05 g of copper is added to excess nitric acid if the total pressure is 726 mm Hg. The vapor pressure of water at 25.0 °C is 23.8 mm Hg.
