Avapor composed of 0.35 mole fraction ethanol and 0.65 mole fraction acetic acid at 120.0 mmhg (absolute), is in equilibrium with a liquid phase also composed of ethanol and acetic acid. assume that the liquid is an ideal solution and apply raoult's law to find the following. what is the temperature of the liquid? number degree c what are the mole fractions of the liquid phase? xe = number mol ethanol/mol xa = number mol acetic acid/mol

Which of the following is an easy way to remember the modified “x” tire rotation? a. nondrive wheels straight, cross the drive wheels b. drive wheels straight, cross the nondrive wheels c. drive wheels crossed, nondrive wheels straight d. drive wheels crossed, nondrive wheels crossed

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
