Indicate the compartment (A or B) that will increase in volume for each of the following pairs of solutions separated by a semi-
avanturin [10]

Based on the concentration of the solutions, the increase in volume is as follows:

  • the volume of the 20% (m/v) starch increases
  • the volume of the 10% (m/v) albumin increases
  • the volume of the 5% (m/v) sucrose increases

<h3>What is osmosis?</h3>

Osmosis is the movement of water molecules from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane.

The movement of water molecules in the solution pairs is as follows:

  • the volume of the 20% (m/v) starch increases because water moves in from the 10% (m/v) starch solution.
  • the volume of the 10% (m/v) albumin increases because water moves in from the 2% (m/v) albumin
  • the volume of the 5% (m/v) sucrose increases because water moves in from the 0.5% (m/v) sucrose.

Therefore, the increase in volume depends on the concentration ofvthe solutions.

Which type of reactions form salts?
Marysya12 [62]

Answer:

Neutralization reactions

Explanation:

A neutralization reaction is a reaction between an acid and a base. Products of this type of reaction is water and a salt. The pH of the salt product would depend on how strong or weak the base and acid would be when they react with each other. Although the characteristics of bases and acids are practically polar opposites, when combined, they cancel each other our producing a neutralized product.

steam azentropic distillation

3.During a steam distillation, How to know if the organic compound is still coming over is when you see the solution becoming cloudy or when there is existence of two layers.

4.)The end of the steam distillation, the receiving flask should contain two layers of liquid, and the chemical identity of these two liquids most contain

A.) Layers that are mostly water H2O

B.) Layers that are mostly products
