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?

Sound energy is produced when an object vibrates. examples are 1- a balloon popping2-a whistle3- a waterfall

Ithink it is c ,i hope i you

Distance covered, s = 8ft - 4ft = 4 ftinitial velocity, u = 34 ft/sthe acrobat is moving upwards and therefore, a = -g = -9.81 m/s^2 = 32.19 ft/s^2applying equation of motion; s = ut -1/2gt^2then,4 = 34t -1/2*32.19t^24 = 34t - 16.095t^2rearranging; -16.095t^2 + 34t - 4 = 0solving the quadratic equation; t = {-34 +/- sqrt [34^2 - 4(-16.)]}/2(-16.095) = 1.06 +/- 0.93 = 0.13 or 1.99the acrobat will take 0.13 seconds to be at 8 ft above the ground. additionally, once at the maximum height, the acrobat will move down and be at the same spot (that is height) after 1.99 seconds moving down.
