Answer:
b
d
a
c
Explanation:
More carbons in longest chain = higher BP
D has a BP of 0.8
A has a BP -0.5
C is the lowest because the more branched it is the lower BP

Answer:
- <em><u>B) Bill's wagon is moving 4 times faster than Tom's. </u></em>
<u />
Explanation:
The motion of the wagons is determined by the net force that acts upon them, according to Newton's second law of motion:
- Force = mass × acceleration ⇒ acceleration = Force / mass
From your data, you can fill this table to compare the accelerations:
Bill's wagon Tom's wagon
mass (lb) 10 20
force 2F F
acceleration 2F/10 F/20
Find the ratio between both accelarations:
- Bill's wagon acceleration / Tom's wagon acceleration
- (2F/10) / (F/20) = (2 × 20 / 10 ) = 4
Meaning that the acceleration of Bill's wagon is 4 times the acceleration of Tom's wagon.
Assuming, that both wagons start from rest, you can obtain the speeds from the kinematic equation for uniformly accelerated motion:
- Speed = acceleration × time, V = a × t.
Call the acceleration of Tom's wagon X, then the acceleration of Bill's wagon will be 4X.
So, depending on the time, using V = a × t, the speeds will vary:
t (s) 1 2 3 4
Speed Tom's wagon X 2X 3X 4X
Speed Bill's wagon 4X 8X 12X 16X
Concluding that Bill's wagon is moving 4 times faster than Tom's (option B).
Convert moles to mass.
mass C = 0.2 mol * 12 g / mol = 2.4 g
mass H = 0.4 mol * 1 g / mol = 0.4 g
So mass left for O = 6 g – (2.4 g + 0.4 g) = 3.2 g
Calculating for moles O given mass:
moles O = 3.2 g / (16 g / mol) = 0.2 moles
