For the acetone(1)/methanol(2) system, a vapor mixture for which z1 = 0.25 and z2 = 0.75 is cooled to temperature t in the two-phase region and flows into a separation chamber at a pressure of 1 bar. if the composition of the liquid product is to be x1 = 0.175, what is the required value of t and what is the value of y1? for liquid mixtures of this system, to a good approximation,

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
