A solution is composed of 1.90 mol cyclohexane (Py = 97.6 torr) and 2.10 mol acetone (Pac = 229.5 torr). What is the total vapor pressure Ptotal above this solution? Express your answer with the appropriate units. ► View Available Hint(s) Ptotal= 167 torr Submit Previous Answers Correct Correct answer is shown. Your answer 166.85 torr was either rounded differently or used a different number of significant figures than required for this part. If a third volatile component had been present in this solution, the total pressure would be calculated in a similar manner but would involve three terms rather than two. For example, Ptotal = PA + PB + Pc = XAPA + XBPg + XcPc Part C As you saw in Part B, the vapor above the cyclohexane-acetone solution is composed of both cyclohexane vapor and acetone vapor. What mole fraction of the vapor above the solution, Xey (vapor), is cyclohexane? Express your answer numerically. ► View Available Hint(s)

When you open a bottle of soda, bubbles rapidly form and gas fizzes out. What is the best explanation of this? Group of answer choices (a) Gas that was trapped at the top of the bottle between the cap and the surface of the liquid escapes immediately and 'draws' liquid soda as it escapes, creating the illusion of bubbling. (b) The act of opening the bottle 'dislodges' tiny, nearly invisible gas bubbles that were clinging to the side of the container. They quickly condense into larger bubbles and escape. (c) Warm air from outside the bottle heats the soda, decreasing the solubility of the CO2 in the soda and causing it to bubble out. (d) When the bottle is opened, the pressure of CO2 gas above the liquid rapidly drops, which significantly decreases the solubility of CO2 in the soda, causing it to bubble out. (e) H2CO3 in the soda reacts with water vapor in the air, forming CO2 that quickly bubbles out.
