A piston-cylinder device contains 0.15 kg of air initially at 2 MPa and 350°C. The air is first expanded isothermally to 500 kPa, then compressed polytropically with a polytropic exponent of 1.2 to the initial pressure, and finally compressed at the constant pressure to the initial state. Determine the boundary work for each process and the net work of the cycle.
Draw the skeletal structure of the enantiomer(s) of (2S,4S)-(+)-rose oxide. (Draw all enantiomers if more than one exists.) Draw the skeletal structure of the diastereomer(s) of (2S,4S)-(+)-rose oxide. (Draw all diastereomers if more than one exists..
