Your manager now tells you that he needs half of the net product as a vapor. What ratio of streams 1 and 2 should you mix and flash at given operating pressure and temperature so as to get the desired product? (7 points) (d) Now you take the product vapor and liquid from (c), mix it and pass it through another flash drum operating at 400 K and 65 atm pressure. What is the composition (mole fractions) of your final liquid and vapor product? Approximate values are acceptable (

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
