[EX Q]: These compounds are described using the E-Z [E dash Z] notation when they occur across alkenes, and a more generalized version of that notation is the cis-trans notation. Both of those are examples of diastereomers [di-uh-stereo-mers], and examples of these include cyclohexane and hexene. Differing bonding patterns make up structural ones of these compounds. When these compounds are mirror images of each other, they are referred to as enantiomers [en-anti-omers]. For 10 points, name these compounds that have varying chemical structures despite having the same chemical formula.
[EX A]: Science

[EX Q]: This man's namesake elasticity describes surface tension resistance when a surface is stretched, and can be applied to surface-tension-related mass transfer in an effect named for this man and Marangoni. For a mixture at constant temperature and pressure, the change in the chemical potential of the system can be obtained using an equation named for this man and Duhem. Another equation named for this man is used to calculate the degrees of freedom of a system depending in part on its number of components. For 10 points, name this man with a namesake phase rule and a thermodynamic quantity useful in predicting the spontaneity of a chemical reaction, his free energy.
[EX A]: Science

[EX Q]: A Pop Art version includes a depiction of the artist herself, Marisol, sitting opposite the scene of wood sculpture. A version by Tintoretto divided the oil on canvas painting diagonally with the table, and includes a choir of angels, while Marisol's inspiration was painted for Santa Maria delle Grazie. Give the titles for these works depicting the moment at which Jesus announces that one apostle will betray him, the best known of which, FTP, was painted by Leonardo da Vinci.
