Which solution is a homogeneous mixture?

Chemistry
2 answers:
Hoochie [10]3 years ago
8 0

Answer:

A homogenous mixture is a mixture that contains a single phase

Explanation:

In the physical sciences, a phase is a region of space, throughout which all physical properties of a material are essentially uniform. Hence when we refer to a phase we mean a region of entirely homogeneous composition.

A solution of ethanol in water constitutes a single phase, only the liquid can be seen. This is a typical example of a homogeneous mixture.

Within the categories of homogeneous and heterogeneous mixtures there are more specific types of mixturesincluding solutions, alloys, suspensions, and colloids. A solutionis a mixture where one of the substances dissolves in the other. The substance that dissolves is called the solute.

The vapor pressure of a liquid in a closed container depends
DerKrebs [107]

Answer:

(c) temperature

Explanation:

In a closed system, as the temperature increases, the molecules in the liquid are exited and converts into gas. The more the gas transformed, the more the gas(vapor) pressure. The less the gas transformed, the less the vapor pressure.

Therefore, temperature is a major factor in vapor pressure.

A certain substance X has a normal freezing point of 5.6 °C and a molal freezing point depression constant Kf-7.78 °C-kg·mol-1.
Harrizon [31]

Answer:

27.60 g urea

Explanation:

The <em>freezing-point depression</em> is expressed by the formula:

  • ΔT= Kf * m

In this case,

  • ΔT = 5.6 - (-0.9) = 6.5 °C
  • Kf = 7.78 °C kg·mol⁻¹

m is the molality of the urea solution in X (mol urea/kg of X)

First we<u> calculate the molality</u>:

  • 6.5 °C = 7.78 °C kg·mol⁻¹ * m
  • m = 0.84 m

Now we<u> calculate the moles of ure</u>a that were dissolved:

550 g X ⇒ 550 / 1000 = 0.550 kg X

  • 0.84 m = mol Urea / 0.550 kg X
  • mol Urea = 0.46 mol

Finally we <u>calculate the mass of urea</u>, using its molecular weight:

  • 0.46 mol * 60.06 g/mol = 27.60 g urea
