You are in working on a project to separate a mixture of hydrocarbons by equilibrium flash operation. The system that you design employs 100-kmol of feed composed of 25 mol% n-butane, 35 mol% nhexane, and 40 mol% n-pentane. In this process n-hexane is flashed. If 80% of the hexane is in the liquid at 240 oF, what are the pressure and the liquid vapor composition?

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.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

50.23 i believe is correct but don't quote me on that.
