Agas mixture containing 85.0 mole% n2 and the balance n n-hexane flows through a pipe at a rate of 100.0 m3/h. the pressure is 2.00 atm absolute and the temperature is 100°c. what is the molar flow rate of the gas in kmol/h? is the gas saturated? if not, to what temperature (°c) would it have to be cooled at constant pressure in order to begin condensing hexane? to what temperature (°c) would the gas have to be cooled at constant pressure in order to condense 80% of the hexane?

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.

the answer to this is proletariats.

hope this : )
