How does maximum boiling azeotropic mixture is separated using fractional distillation?

Chemistry
1 answer:
Evgesh-ka [11]2 years ago
4 0

Answer:

By heating the mixture to maximum boiling point and then the solution is distilled at a constant temperature without having a change in composition.

Explanation:

An azeotropic mixture is also called a constant boiling mixture and it is a mixture of two or more liquids whose proportions cannot be altered by simple distillation due to the fact that when an azeotropic mixture is boiled, the vapor has the same proportions of constituents as the unboiled mixture.

Now, maximum boiling azeotropic mixture are the solutions with negative deviations that have an intermediate composition  for which the vapor pressure of the solution is minimum and as a result, the boiling point is maximum. At that point, the solution will distill at a constant temperature without having a change in composition.

Which group/family contains elements with the smallest radius within the same period?
nasty-shy [4]

Answer:

Halogens

Explanation:

From the given choices, the halogens will have the smallest radius within the same period.

The size of an atom is estimated by the atomic radius. This is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state.

  • Across a period in the periodic table, atomic radii decrease progressively from left to right.
  • Down a group from top to bottom, atomic radii increase progressively due to the addition of successive shells.

Since halogen is the right most group from the choices given, it will have the smallest radius.

Predict whether each of the following substances would be more soluble in water (polar solvent) or in a hydrocarbon such as hept
vlada-n [284]

Answer:

Vegetable oil will dissolve in heptane

Isopropyl alcohol will dissolve in water

Potassium Bromide will dissolve in water

Explanation:

In chemistry, like dissolves like. This implies that polar substances will dissolve in polar solvents and nonpolar substances will dissolve in nonpolar solvents. This is so because, dissolution of a solute in a solvent involves adequate intermolecular interaction between solute and solvent which isn't possible between a polar and a nonpolar substance.

Nadusha1986 [10]

Answer:

Sea breeze moves from the areas of higher pressure on the water in the direction of the areas of lower pressure on land.

Explanation:

Sea breeze moves from the areas of higher pressure on the water in the direction of the areas of lower pressure on land. Whereas, land breeze blows from the areas of higher pressure on land to the areas of lower pressure on water.
