The mole faction of co2 in air is 0.00033 at present and rising. co2 is known to have its triple point (first vle point) at -56.4°c and 5.11 atm and its critical point (last vle point) at t. = 304.2 k and p 73.83 bar = ahyap > 1 always holds. briefly explain if co2 have a normal boiling (a) considering the fact that az"ap temperature? (b) use the corresponding-state "short-cut" method and a-0.224 (table b.1) to obtain a hypothetical normal boiling temperature for co2. (c) use the following antoine equation provided by national institute of standards and technology (nist) to estimate the hypothetical normal boiling point of co2. how do (b) and (c) compare to reported value of -78.5 °c? 1301.679 log10 p(bar 6.81228 - t(°c) 269.656 (d) one way to remove/reduce co2 from/in the air is to compress air to liquefy co2. is it thermodynamically possible at 25°c?

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
