After a student completed the reaction for the acid-catalyzed dehyration of 2-methyl-2-butanol, the student then injected the sample into the gas chromatography (GC) instrument. While one peak was expected, the chromatograph produced three peaks (not including any reference or air peak). Which of the following best explains this observation?
If the gravitational potential energy of a 35.0 kg rock is 500. J relative to a value of zero on the ground, how high is the rock above the ground
Using these and other relevant data, determine the rate of entropy generation in that power plant.
An electron moves in a region where the magnetic field is uniform, has a magnitude of 60 mT, and points in the positive x direction. Determine the pitch of the resulting helical path
A bumper car with mass m1 = 109.0 kg is moving to the right with a velocity of v1 = 4.9 m/s. A second bumper car with mass m2 = 84.0 kg is moving to the left with a velocity of v2 = -3.6 m/s. The two cars have an elastic collision. Assume the surf..
