The properties of noble gases include:
- They are nonreactive
- They have hight ionisation energy
- They have low boiling point
- They conduct electricity at low pressure.
The noble gases are those elements that makes up the group 18 of the periodic table.
They are non as the inert gases because they are relatively nonreactive.
According to the electronic arrangement, which is according to how the electrons are arranged on their shells, they can exist alone.
The noble gases are nonreactive, have high ionisation energy and low boiling point because in its electronic arrangement, the outer shell is completely full.

It is a mixture
Explanation:
Food coloring is able to separate into different dyes because it just a simple mixture of different color pigments.
Under a chromatogram the different colors will migrate relatively over an absorbent.
A mixture is an impure substance with the following properties:
- composition is indefinite as they are made up of two or more elements or compounds in any proportion by mass.
- They are able to retain their identities i.e physical properties are maintained.
- Their constituents reacts differently to changed conditions.
- They can easily be separated into constituent by physical methods.

Answer:
The compound which will precipitate first will be AgI with 
Explanation:
In order to precipitate a salt solution the ionic product of salt must exceed the solubility product.
Given:
Ksp of AgI = 
Ksp of PbI2= 
As Ksp of AgI is very low it will precipitate faster than lead iodide.
Now, higher the concentration of AgI solution taken faster its precipitation.
In the given choice the highest concentration solution of AgI is
