An extensive property is a property that depends on the amount of matter in a sample. Mass and volume are examples of extensive properties. ... Color, temperature, and solubility
The correct answer is A: Vapor pressure lowering.
Certain properties in chemistry are called colligative properties. These colligative properties depends on the amount of solute present.
Examples of colligative properties include;
- Vapor pressure lowering
- Freezing point depression
- Boiling point elevation
- Osmotic pressure
When a solute is introduced into water, the vapour pressure of water is lowered.
Hence, when KI is added to a sample of water, vapor pressure lowering occurs.

Answer:
The product will be propanoic acid .
Explanation:
Under the action of strong oxidizing agent that is potassium dichromate in an acidic medium primary oxidizes the primary alcohols into carboxylic acid .
