Consider a closed vessel initially containing 1 mol of pure ethyl acetate at 70°c and 86 kpa. imagine that pure ethanol is slowly added at constant temperature and pressure until the vessel contains 1 mol ethyl acetate and 9 mol ethanol. describe the evolution of phases and phase compositions during this process. comment on the practical feasibility of carrying out such a process. what sort of device would be required? how would the total system volume change during this process? at what composition would the system volume reach its maximum value?

Iknow #2 is d. i just need to know why

Fugu, also known as puffer fish, is a sushi delicacy that can also be lethal. puffer fish contain a powerful toxin that can kill an adult a few hours after ingestion. sushi chefs who prepare fugu must be specially trained because any contamination of the toxin-free areas of the fish can be deadly. recently this toxin has been put to good use, as scientists have discovered that a purified form of it can treat severe pain in cancer patients. this recent scientific discovery would fall under which area of chemistry? applied biochemistry pure organic chemistry pure physical chemistry applied inorganic chemistry
