Answer:

Energy added: particles move faster and further apart, and matter expands (state changes from solid to liquid to gas). Energy removed: particles move slower and closer together, and matter contracts (state changes from gas to liquid to solid).

<h2>Answer:-</h2>

The female part is the pistil. The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tube like structure called the style.

Fossil originally has 254 g of carbon-14 but currently has 127 g of carbon-14 the fossil is most likely

KATRIN_1 [288]

Answer:

The answer to your question is: letter C) 5730

Explanation:

Data

Originally Carbon - 14 254 g

Currently Carbon - 14 127 g

Half-life of Carbon -14 is when half of the original amount of Carbon disintegrates.

Then, if originally there were 254 and now there are 127, only one half life passed.

Half life of carbon -14 is 5730 years old.

In a solution composed of benzene and toluene that has a vapor pressure of 32 torr at 20°C, what is the mole fraction of benzene

taurus [48]

Answer:

The mole fraction of benzene if 0.43

Explanation:

Let's apply the colligative property of vapor pressure lowering.

P° - Ps = P° . Xm

Where P° is vapor pressure of pure solvent

Ps is vapor pressure of solution

Xm is mole fraction of solute

Determine the solute and the solvent:

Solute: Toluene

Solvent: Benzene (Vapor pressure of pure bencene at 20°C, is 74.7Torr)

74.7 Torr - 32 Torr = 74.7 Torr . Xm

42.7 Torr / 74.7 Torr = 0.57 → Xm

Sum of mole fraction = 1

Mole fraction of bencene + Mole fraction of toluene = 1

Mole fraction of bencene + 0.57 = 1 ⇒ 1 - 0.57 = 0.43
