Answer:

Paraffin > Heptadecane > Hexane > 2,2-dimethylbutane > Propane

Explanation:

It must first be establish that all the molecules listed in the question are alkanes. For alkanes, the intermolecular forces between the molecules of alkanes increases with increasing molecular weight. This is as a result of increase in the surface area of the molecule. Increase in surface area implies a greater degree of dispersion forces.

This is the reason why high boiling points are observed for high molecular weight alkanes.

Why do living things need water, food, and space
telo118 [61]
In order to survive, all living things need air, water, and food. Animals obtain their food from plants and other animals, which provides them with the energy they need to move and grow. An animal's home (habitat) must provide these basic needs (air, water and food) along with shelter from bad weather and predators.!!!!!!!

Calculate the frequency of a beam of light that is 35.6m long.
Vladimir [108]

Answer:

f = 0.084 s⁻¹

Explanation:

Given data:

Frequency of light = ?

Wavelength = 35.6 m

Solution:

Formula:

Speed of light = wavelength × frequency

Speed of light = 3× 10⁸ m/s

by putting values,

3× 10⁸ m/s = 35.6 m ×  f

f = 3× 10⁸ m/s / 35.6 m

f = 0.084 s⁻¹

Illusion [34]

Answer:

I would say a cooled

Explanation:

because yeah it's going to be cold when it travels from Antarctica but then it's going on towards Africa and yeah the water is going to get warmth but it's going to cool the land of Antarctica because it's so dry and hot and humid but the water is going to be more warmed because Antarctica the water is freezing so you're trying to ask the temperature of the water it'd be more warm if you're trying to ask kind of like the temperature of the land it would be cooled

pogonyaev

Answer:

3 salad = 3 lettuce + 6 tomatoes + 9 three carrots

Coefficients: 3, 6, 9

Explanation:

1 salad = 1 lettuce + 2 tomatoes + 3 three carrots

<em>Multiply all the coefficients of 1 salad by 3:</em>

3(1 salad) = 3(1 lettuce + 2 tomatoes + 3 three carrots)

<em>Expand the equation:</em>

3 salad = 3 lettuce + 6 tomatoes + 9 three carrots
