Asolution contains 42.0 g of heptane (c7h16) and 50.5 g of octane (c8h18) at 25 ∘c. the vapor pressures of pure heptane and pure octane at 25 ∘c are 45.8 torr and 10.9 torr, respectively. assuming ideal behavior, calculate each of the following. (note that the mole fraction of an individual gas component in an ideal gas mixture can be expressed in terms of the component's partial pressure.)a.) the vapor pressure of each of the solution components in the mixtureb.) the total pressure above the solutionc.) the composition of the vapor in mass percentd.) why is the composition of the vapor different from the composition of the solution?

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!
