Joelle is a manager at a construction company, and she is interested in the chemistry behind the materials they use. she has begun studying the materials used to fill walls. she knows that to keep the temperature inside a room steady the material must be a thermal insulator, and she predicts that materials should not be acidic or else they would dissolve too easily in water. which is most likely a molecule in a wall-filling material?

Answer : Option A) Benzene

Explanation : Benzene is organic in nature and cannot dissolve in water. Benzene also acts as an thermal insulator because it has delocalized electrons which cannot move its electrons to conduct heat and electricity. Therefore, it is used in wall filler to maintain the temperature inside the room.

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.
