One hundred kilogram-moles per hour of a feed containing 30 mole% n-hexane and 70% n- octane is to be distilled in a column consisting of a partial reboiler, a theoretical plate, and a partial condenser, all operating at 1 atm (101.3 kpa). the feed, a bubble-point liquid, is fed to the reboiler, from which a liquid bottoms product is continuously withdrawn. bubble-point reflux is returned to the plate. the vapor distillate contains 80 mole% hexane, and the reflux ratio (lrd) is 2 assume the partial reboiler, plate, and partial condenser each function as an equilibrium stage. (a) using the mccabe-thiele method, calculate the bottoms composition and moles of distillate produced per hour.

answer: a chemical reaction

explanation:

im not wrong

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
