Afour component mixture is fed to a flash chamber. the mixture is composed of the following, all in mole fractions: a) n-butane (0.425); b) n-pentane (0.125); c) n-hexane (0.205); and n-heptane. the flash unit operates at a pressure of 2 atm. a)find the bubble point temperature (assume the feed comes in as a liquid) and the composition of the vapor phase in equilibrium with the liquid phase at this point; b)find the dew point temperature (assume the feed comes in as a vapor) and the composition of the liquid phase in equilibrium with the vapor phase at this point; c)find the temperature and composition of both liquid and vapor phases when 40% of the feed is vaporized in a flash distillation. d)use chemcad to solve these problems and compare your results to the predictions from chemcad.

Element before carbon on the periodic table

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
