A total feed of 200 mol/h having an overall composition of 42 mol% heptane and 58 mol% ethyl benzene is to be fractionated at 101.32 kPa abs pressure to give a distillate containing 97 mol% heptane and a bottoms containing 1.1 mol% heptane. The feed enters the tower partially vaporized so that 40 mol% is liquid and 60 mol% is vapor. Equilibrium data are given in the previous problem statement. Calculate the following: (a) Moles per hour distillate and bottoms (b) Minimum reflux ratio (c) Minimum stages at total reflux (d) Theoretical number of trays required for an

3. if the dartboard below is used to model an atom, which subatomic particles would be located at z?

Brainliesttt me asap! the below reaction can be categorized as more than one type of reaction. which reactions are these, and what are the types of reactions?

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
