Which is true of vapour pressure? a. it is affected by the surface area of the liquid or solid.
b. Vapour pressure is higher when the temperature of the molecule is low.
c. Molecules with high molar heat of vaporization has low vapour pressure.
d. when vapour pressure is lower than atmospheric pressure, boiling occurs. ​

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

pie chart because it is in percents ( % )

i believe the answer is true.
