Sunflower oil contains 0.080 mol palmitic acid (c16h32o2)/mol, 0.060 mol stearic acid (c18h36o2)/mol, 0.27 mol oleic acid (c18h34o2)/mol, and 0.59 mol linoleic acid (c18h32o2)/mol. to create margarine from sunflower oil, the liquid oleic and linoleic acids are hydrogenated in the presence of a metal catalyst to form solid stearic acid. at a margarine production facility, a stream of 335.0 mol sunflower oil/hr is fed into a reactor. the fresh hydrogen source available is a mixture containing 0.95 mol h2/mol and 0.050 mol n2/mol. (n2 is inert in this process.) to insure complete hydrogenation, the hydrogen gas mixture is introduced into the reactor in 65.0% excess. all reaction products leave the reactor and proceed to a separator where palmitic and stearic acids are separated from the hydrogen gas mixture. the hydrogen gas mixture is recycled to the fresh feed stream, and 140.0 mol gas/hr of this recycle stream is purged to prevent the buildup of nitrogen gas. what is the composition of the purge stream?

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

When water dissolves sugar, which process is not involved? o dissociation o hydration o surface area of the solute increases sa

The activation energy for this reaction is 75 kj·mol–1. the enzyme catalase (found in blood) lowers the activation energy to 8.0 kj·mol–1. at what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25°c?
