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?

B. that is the answer

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3
